The Honorable Norm Dicks: 
Ranking Minority Member: 
Subcommittee on Interior and Related Agencies: 
Committee on Appropriations: 
House of Representatives: 

Dear Mr. Dicks: 

The Bureau of Land Management, within the Department of the Interior, 
and the Forest Service, within the U.S. Department of Agriculture, 
manage over 41 million acres of federal lands in Oregon and 
Washington, including 122,000 miles of roads that use culverts—pipes 
or arches made of concrete or metal—to allow water to flow from one 
side of the road to the other. Many of the streams that pass through 
these culverts are essential habitat for fish and other aquatic 
species. When culvert openings are too high above the streams for fish 
to jump into or culverts are positioned at a grade too steep for fish 
to ascend, they pose barriers to fish attempting to access their 
natural rearing and spawning habitat. Passage through culverts is 
particularly important to anadromous fish, such as Coho and Chinook 
salmon (some of which are threatened or endangered), which are spawned 
in freshwater streams, but must travel to the ocean to mature, then 
travel back to the streams to spawn. The two agencies are concerned 
about the condition of the culverts on fish bearing streams on their 
Oregon and Washington lands because many, either because of 
deterioration or design, do not provide passage for all life stages 
(juvenile to adult) as required by current standards. 

In this context, you asked us to determine (1) the number of culverts 
that may impede fish passage on Bureau of Land Management and Forest 
Service lands in Oregon and Washington, (2) the factors affecting the 
agencies' ability to restore passage through culverts acting as 
barriers to fish (hereafter referred to as barrier culverts), and (3) 
the results of the agencies' efforts to restore fish passage. 

Results in Brief: 

Over 10,000 culverts exist on fish-bearing streams in Oregon and
Washington according to Bureau of Land Management and the Forest 
Service estimates, but neither agency knows the total number that 
impede fish passage. Ongoing agency inventory and assessment efforts 
have already identified nearly 2,600 barrier culverts, but agency 
officials estimate that more than twice that number may exist. The 
Forest Service plans to complete its assessment by the end of calendar 
year 2001. The Bureau of Land Management has not set a specific 
completion date for assessing all culverts, but intends to continue 
assessing culverts as part of its ongoing land management planning 
efforts. According to officials, both agencies intend to use the 
assessments to assist them in planning and setting priorities for 
eliminating barrier culverts. Based on current assessments, the 
agencies estimate that efforts to restore fish passage may ultimately 
cost over $375 million and take decades. 

Although the agencies recognize the importance of restoring fish 
passage, several factors are inhibiting agencies' efforts. Most 
significantly, the agencies have not made sufficient funds available 
to do all the culvert project work necessary. In allocating road 
maintenance funds, the agencies assign a relatively low priority to 
such fish passage projects because road safety is a higher priority 
than resource protection. As a result, the agencies allocate most 
maintenance funding to address their large road maintenance backlogs 
rather than to undertake culvert projects. In addition, the often 
lengthy process of obtaining federal and state environmental 
clearances and permits to perform culvert work, as well as the short 
seasonal "window of opportunity" to do the work, affects the agencies' 
ability to restore fish passages quickly. Furthermore, the shortage of 
experienced engineering staff limits the number of projects that the 
agencies can design and complete. Currently, each barrier removal 
project generally takes 1 to 2 years from start to finish. 

The Forest Service and the Bureau of Land Management completed 141 
culvert projects from fiscal year 1998 through August 1, 2001, to 
remove barriers to anadromous fish and to open an estimated 171 miles 
of fish habitat. Neither agency, however, knows the extent to which 
culvert projects ultimately result in improved fish passage because 
neither agency requires systematic post-project monitoring to measure 
the outcomes of their efforts. The agencies say they do not perform 
post-project monitoring because of limited funding and staff 
availability and, according to agency officials, because they assume 
culverts built using current standards on lands under their 
jurisdiction should allow fish passage. State and local entities using 
these same standards, however, require systematic post-project 
monitoring to ensure that they used the most effective methods for 
improving fish passage under various conditions. Oregon's monitoring 
results, for example, indicate that retrofitting culverts with devices 
that slow the flow of water can effectively restore fish passage. 
Without monitoring, neither the Forest Service nor the Bureau of Land 
Management can ensure that the federal moneys expended to improve fish 
passage are actually achieving the intended purpose. This report 
recommends that both agencies develop guidance for systematically 
assessing completed barrier removal projects to determine whether they 
are improving fish passage as intended. The agencies agreed with our 
recommendation for systematic monitoring. 

Background: 

The Bureau of Land Management (BLM) and the Forest Service manage most 
of the nation's 655 million acres of federal land. BLM is responsible 
for about 264 million acres of public lands, managed by 12 state 
offices that are responsible for supervising the operations of 175 
field offices nationwide. The Forest Service is responsible for about 
192 million acres of public lands, managed by 9 regional offices that 
are responsible for supervising the operations of 155 national forests. 

BLM and the Forest Service manage about 93 percent of the 44 million 
acres of federally owned land in Oregon and Washington. BLM's Oregon 
State Office manages about 17 million acres of land in the two states, 
including over 28,000 miles of roads. The state office directs the 
operations of 10 district offices--9 in Oregon and 1 in Washington-—
each responsible for managing BLM's public land resources within its 
geographic jurisdiction. Six of the Oregon districts contain Oregon and
California Grant Lands, distributed in a checkerboard pattern within 
each district, and interspersed within and around the federal lands is 
state and private lands. The Forest Service's Region 6 manages about 
25 million acres of land in the two states, including nearly 94,000 
miles of roads. Region 6 directs the operations of 19 national forests-
13 in Oregon and 6 in Washington. BLM's district offices and the 
Forest Service's national forest offices perform similar land 
management functions, including restoration of fish and wildlife 
habitat and designing, constructing, and maintaining roads.[Footnote 1] 

BLM and Forest Service land management activities regarding fish 
habitat in Oregon and Washington are governed by three regional 
agreements: the Northwest Forest Plan, signed in 1994 for activities 
on the west side of the Cascade mountain range, and PACFISH and 
INFISH, signed in 1995, for activities on the east side of the range. 
[Footnote 2] Both agencies are required to direct their land 
management activities toward achieving the objectives of the three 
agreements. The Northwest Forest Plan's Aquatic Conservation
Strategy includes the objective of maintaining and restoring 
"connectivity within and between watersheds," which must provide 
"unobstructed routes to areas critical for fulfilling the life history 
requirements" of aquatic species.[Footnote 3] In addition, the 
Northwest Forest Plan's road management guidelines state that the 
agencies shall "provide and maintain fish passage at all road 
crossings of existing and potential fish-bearing streams."[Footnote 4] 
PACFISH includes the objective of achieving "a high level of habitat 
diversity and complexity...to meet the life-history requirements of 
the anadromous fish community inhabiting a watershed." The PACFISH 
road management guidelines duplicate the Northwest Forest Plan 
guidance. INFISH provides similar management objectives and guidance 
for resident native fish outside of anadromous fish habitat. 

Maintaining fish passage and habitat is particularly important for 
anadromous fish, which as juveniles migrate up and down stream 
channels seasonally, then travel from their freshwater spawning 
grounds to the ocean where they mature, and finally return to their 
spawning grounds to complete their life cycle. Under the authority of 
the Endangered Species Act, the National Marine Fisheries Service 
currently lists four species of salmon—including Coho, Chinook, Chum, 
and Sockeye—as well as steelhead and sea-run trout as either 
threatened or endangered anadromous fish in the northwest region. 
According to agency officials, BLM and Forest Service lands in Oregon 
and Washington include watersheds that represent some of the best 
remaining habitat for salmon and other aquatic life, often serving as 
refuge areas for the recovery of listed species. As such, unobstructed 
passage into and within these watersheds is critical. 

Culverts—-generally pipes or arches made of concrete or metal-—are 
commonly used by BLM and the Forest Service to permit water to flow 
beneath roads where they cross streams, thereby preventing road 
erosion and allowing the water to follow its natural course. Culverts 
come in a variety of shapes and sizes, designed to fit the 
circumstances at each stream crossing, such as the width of the stream 
or the slope of the terrain. Historically, agency engineers designed 
culverts for water drainage and passage of adult fish. However, as a 
culvert ages, the pipe itself and conditions at the inlet and outlet 
can degrade such that even strong swimming adult fish cannot pass 
through the culvert. The agencies remove, repair, or replace culverts 
to restore fish passage, as shown in figure 1.

[End of figure] 

To meet the objectives of the Northwest Forest Plan and PACFISH, as 
well as Oregon and Washington state standards, current culvert repair 
or replacement efforts must result in a culvert that allows the 
passage of all life stages of fish, from juvenile to adult. 

Extent to Which Barrier Culverts Block Fish Passage Is Unknown: 

As of August 1, 2001, the agencies' fish passage assessments 
identified almost 2,600 barrier culverts—over 400 on BLM lands and 
nearly 2,200 on Forest Service lands—and agency officials estimate 
that, in total, up to 5,500 fish barrier culverts may exist. BLM's 10 
district offices are collecting culvert information as part of their 
ongoing watershed analysis activities and have not established a date 
for completing all culvert assessments. The Forest Service, using a 
regionwide fish passage assessment protocol, plans to complete data 
collection for all of its 19 forests by the end of calendar year 2001. 
The culvert information the agencies are collecting will help them 
coordinate and prioritize culvert repair, replacement, and removal 
efforts. Based on their current knowledge of culvert conditions, the 
agencies project that to restore fish passage at all barrier culverts 
could cost over $375 million and take decades to finish. 

Agencies' Assessments to Determine Maintenance Status of Culverts Are 
Ongoing: 

BLM's district offices are assessing fish passage through culverts as 
part of the ongoing land management activity of a watershed analysis. 
A watershed analysis—-a systematic procedure to characterize the 
aquatic (in-stream), riparian (near stream) and terrestrial (remaining 
land area) features within a watershed—-is a requirement of the 
Northwest Forest Plan and provides the foundation for implementing 
stream and river enhancement projects, timber sales, and road building 
and decommissioning projects. According to an agency official, the 
extent to which a watershed analysis has been completed varies by 
district. The five western Oregon districts entirely within the 
Northwest Forest Plan's jurisdiction, which contain 98 percent of 
BLM's culverts on fish-bearing streams, have completed watershed 
analyses for 87 to 100 percent of their lands. The range for the 
remaining five districts is 0 to 18 percent. Each BLM district office 
maintains its own records regarding barrier culverts on its lands. As 
of August 1, 2001, BLM's district offices had assessed 1,152 culverts 
for fish passage and identified 414 barrier culverts. BLM plans to 
continue its ongoing watershed analysis process, and estimates, based 
on assessments to date, that an additional 282 barrier culverts may be 
identified, for a total of 696 culverts blocking fish passage. 

The Forest Service initiated a regionwide assessment of culverts on 
fish-bearing streams in fiscal year 1999 to determine the scope of 
fish passage problems and to create a database of culvert information 
that will allow it to prioritize projects to address barrier culverts 
on a regionwide basis. The region first developed written guidance and 
provided implementation training to staff at each forest office. In 
fiscal year 2000, 13 of the 19 forests conducted the assessments and 
reported the results to the region's fish passage assessment database. 
In fiscal year 2001, the remaining six forest offices initiated their 
assessments and follow-up and verification of the first year's results 
is ongoing. As of August 2001, the forest offices had assessed 2,986 
culverts for fish passage and identified 2,160—-or about 72 percent-—
as barrier culverts. The region plans to complete its assessment by 
December 2001, and based on its findings thus far, estimates that an 
additional 2,645 barrier culverts may be identified, for a total of 
4,805 culverts blocking fish passage. 

On the basis of information collected as of August 1, 2001, the two 
agencies estimate a total of 10,215 culverts on fish-bearing streams 
under their jurisdictions-2,822 culverts on BLM lands and 7,393 
culverts on Forest Service lands—as shown in figure 2.

efforts is provided in appendix I. 

Assessment Results Will Help Prioritize Reduction of Barrier Backlog: 

Additional ground work is necessary before both agencies have complete 
information on the extent of barrier culverts on their Oregon and 
Washington lands, and as such, neither agency has established a 
process for prioritizing passage restoration projects on a regionwide 
basis. However, the agencies are using the fish passage information 
they have collected to help them coordinate and prioritize culvert 
repair, replacement, and removal efforts on a more limited scale. 

For example, officials at BLM's Coos Bay district stated that through 
the ongoing culvert assessment process, they annually reprioritize 
culvert projects for each resource area within the district and for 
each watershed within each resource area, thus ensuring that the most 
critical barriers are addressed first. In addition, according to BLM 
state office officials, some culverts identified by district offices 
as fish passage barriers are included in their deferred maintenance 
and capital improvement project backlog and evaluated for funding 
among other road and facility projects. State office officials stated 
that while culvert passage restoration projects have not ranked high 
due to the critical nature of other backlog projects, they expect 
barrier culvert projects to move up the list for funding as the 
backlog is reduced. 

National forest offices use their culvert fish passage assessment 
information to assist them in prioritizing culvert maintenance 
activities and for broader road management planning purposes. For 
example, in fiscal year 2001, regional officials directed each forest 
office to identify its top five culvert passage restoration projects 
when submitting its final assessment report. The region considered 
these projects for funding; however, according to a regional office 
official, it is not known how many of these projects were actually 
completed. In addition, Olympic National Forest officials stated that 
they have developed a draft road management strategy that uses the 
fish passage assessment results as input to assist them in further 
prioritizing of road projects identified by the strategy. 

Although BLM and the Forest Service are currently addressing barrier 
culverts based on the assessment information they have collected, 
agency officials estimate, based on their results to date, that it may 
cost over $375 million and take decades to restore fish passage at all 
barrier culverts. BLM officials estimate a total cost of approximately 
$46 million to eliminate their backlog of about 700 barrier culverts, 
while Forest Service officials estimate a total cost of about $331 
million to eliminate their backlog of approximately 4,800 barrier 
culverts. At the current rate of replacement, BLM officials estimate 
that it will take 25 years to restore fish passage through all barrier 
culverts, and Forest Service officials estimate that they will need 
more than 100 years to eliminate all barrier culverts. Furthermore, 
these estimates do not reflect any growth in the backlog due to future 
deterioration of culverts that currently function properly. 

Several Factors Affect Agencies' Ability to Eliminate Barrier Culverts 
Quickly: 

According to BLM and Forest Service officials, several factors 
restrict their ability to quickly address the long list of problem 
culverts. Of most significance, the agencies assign a relatively low 
priority to such culvert projects when allocating road maintenance 
funds because ensuring road safety is the top priority for road 
maintenance, repair, and construction funds. Both agencies emphasize 
reducing the backlog of road maintenance rather than specifically 
correcting barrier culverts. Because neither agency requests funds 
specifically for barrier culvert projects, district and forest offices 
must fund these restoration projects within their existing budgets, 
and these projects must compete with other road maintenance projects 
for the limited funds. Therefore, to restore fish passage, the 
agencies largely rely on other internal or external funding sources 
not dedicated to barrier removal nor guaranteed to be available from 
year-to-year. Other factors affecting the agencies' efforts to restore 
fish passage include the complex and lengthy federal and state project 
approval process to obtain environmental clearances and the limited 
number of agency engineers experienced in designing culverts that meet 
current fish passage requirements. Furthermore, to minimize 
disturbance to fish and wildlife habitat, states impose a short 
seasonal "window of opportunity" within which restoration work on 
barrier culverts can occur. As a result, each barrier removal project 
generally takes 1 to 2 years from start to finish. 

Barrier Culvert Projects Compete With Other Road Maintenance 
Priorities for Limited Funding: 

Both BLM and the Forest Service regard culverts as a component of 
their road system-—similar to bridges, railings, signs, and gates—-
each requiring maintenance, including repair, replacement, and removal 
to ensure safe operation. As such, each agency requests funding for 
road maintenance as a total program of work rather than requesting 
funding specifically for culvert maintenance, or more specifically, to 
restore fish passage at barrier culverts. Furthermore, according to 
agency guidance, ensuring road safety is the top priority for road 
maintenance activities rather than removing barrier culverts. 

Individual forest and district offices must fund culvert projects 
within their road maintenance allocations, compete with other units 
for deferred maintenance funds, or use other funding sources. BLM's 
state office and the Forest Service's regional office each allocate 
annual road maintenance funds to districts and forests primarily based 
on the miles of roads each contains and distribute additional funds to 
those units for maintenance projects on a competitive basis. BLM's 
fiscal year 2001 annual road maintenance funding totaled about $6 
million, while according to officials, about $32 million is required 
to meet annual maintenance needs, including culverts. The Forest 
Service's fiscal year 2001 annual road maintenance funding totaled 
about $32 million, while according to officials, about $129 million is 
required to meet their annual maintenance needs, including culverts. 
Due to their large backlogs of deferred maintenance, officials of both 
agencies stated that deferred maintenance funds have not been 
distributed to district or forest offices for fish passage restoration 
projects. 

In the absence of sufficient road maintenance funding, the district 
and forest offices largely rely on other internal or external funding 
sources not specifically dedicated to barrier removal nor guaranteed 
to be available from year-to-year to restore anadromous fish passage 
at barrier culverts. As shown in figure 3, BLM's district offices 
reported that since fiscal year 1998, they relied almost entirely on 
Jobs-In-The-Woods program funding, which seeks to support displaced 
timber industry workers within BLM's Oregon and California Grant 
Lands. BLM distributes this funding to the western districts in Oregon 
containing the Oregon and California Grant Lands to fund contracts 
with local workers to do stream restoration projects, including 
barrier culvert repair and replacement. While BLM officials view the 
Jobs-In-The-Woods program as an ongoing source of funding for culvert 
projects, this funding source is not dedicated to barrier removal and 
BLM may use these funds for a variety of other resource programs or 
projects. Other BLM barrier culvert project funding sources include 
timber sales and the Federal Highway Administration's Emergency
Relief for Federally-owned Roads to replace storm-damaged culverts.

[End of figure] 

As shown in figure 4, national forest offices reported that since 
fiscal year 1998 they have primarily relied on the Federal Highway 
Administration's funding and the National Forest Roads and Trails 
funds for projects to restore anadromous fish passage at barrier 
culverts. Due to severe flooding in recent years and widespread damage 
to culverts, forest offices obtained Federal Highway Administration 
funds to replace damaged culverts and concurrently ensure these 
culverts meet current fish passage standards. While such funds enabled 
the forest offices to address barrier culverts, the forest offices 
cannot rely on future flood events to ensure a steady stream of 
funding for such projects. National Forest Roads and Trails funds 
consist of 10 percent of the receipts of the national forests made 
available to supplement annual appropriations for road and trail 
construction and projects that improve forest health conditions. 
Forest offices used these funds to restore fish passage at barrier 
culverts and to fund their ongoing culvert fish passage assessment 
effort. These funds, however, are not dedicated to fish passage 
projects, but rather culvert projects compete with other road projects 
for these funds on a regionwide basis. Other funding sources for 
Forest Service fish passage projects include Jobs-In-The-Woods and 
timber sales.[Footnote 5]

Factors Affecting Project Design, Approval, and Construction Restrict 
Agencies' Efforts to Eliminate Barriers: 

In addition to limitations on the amount of funding available for 
barrier culvert projects and uncertainty regarding the continuity of 
such funding, three other factors affect the agencies' efforts to 
restore fish passage. These factors are (1) the complex and lengthy 
federal and state project approval process, (2) the limited number of 
agency engineers with experience designing culverts that meet current 
fish passage standards, and (3) the short seasonal "window of 
opportunity" during which work on barrier culverts can occur. Each of 
these factors affects the time frame needed to complete each of the 
major phases of a barrier culvert project—-specifically, obtaining 
necessary permits and clearances, designing the culvert, and 
constructing the culvert-—and consequently impacts the number of 
projects that can be completed annually. Due to these factors, culvert 
projects to restore culvert fish passage take 1 to 2 years to 
complete, according to BLM and Forest Service officials. 

First, BLM and Forest Service officials stated that the number of fish 
passage projects the agencies can undertake and the speed with which 
they can be completed depend largely on how long it takes to obtain 
the various federal and state clearances necessary to implement a 
culvert project. Under the National Environmental Policy Act, an 
assessment of each project's impact on the environment must be 
completed before construction can commence. If the assessment 
indicates that an endangered species may be adversely affected by the 
project, Section 7 of the Endangered Species Act of 1973 requires the 
agency to consult with the appropriate authority—generally the 
National Marine Fisheries Service for anadromous fish and the Fish and 
Wildlife Service for other species—to reach agreement on how to 
mitigate the disturbance. BLM and the Forest Service have entered into 
an agreement with the consulting agencies to expedite the process 
through streamlined procedures. However, according to agency 
representatives, factors such as staffing shortages and turnover, as 
well as differing interpretations of the streamlining guidance, have 
prevented the revised consultation process from producing the 
efficiencies desired by the agencies, and it is currently under 
review. In addition to consultation: 

* the U.S. Army Corps of Engineers requires a permit for fill or 
excavation in waterways and wetlands; 

* Oregon requires a "removal and fill" permit for in-stream 
construction; and; 

* Washington requires a hydraulic project permit to engage in 
construction activities within streams. 

According to information provided by district and forest offices for 
56 completed culvert projects, the clearance and permit process is the 
most time-consuming phase of a culvert project, ranging from a low of 
4 weeks to a high of 113 weeks, for an average of about 31 weeks. 

Second, BLM's and the Forest Service's efforts to eliminate barrier 
culverts are restricted, according to agency officials, by the limited 
number of engineers available to design them, and more specifically, 
the few with experience in designing culverts that meet current fish 
passage requirements. As a result, district and forest officials 
speculate that additional hiring or contracting with engineering firms 
for culvert design work may be necessary if greater emphasis is placed 
on reducing the barrier culvert backlog. Agency officials also 
emphasized the need for more fish biologists, hydrologists, and other 
professionals with fish passage design skills. According to time frame 
information provided by district and forest offices for 56 completed 
culvert projects, the design process is the second most time-consuming 
phase of a project, ranging from a low of 4 weeks to a high of 78 
weeks to complete, for an average of about 19 weeks. 

Finally, BLM and Forest Service officials stated that their efforts to 
eliminate barrier culverts are limited by a short seasonal "window of 
opportunity" of about 3 months during which fish passage restoration 
work—-that is, construction work within streams—-can occur. Oregon and
Washington have established these time frames to minimize the impacts 
to important fish, wildlife, and habitat resources. The summer to fall 
in-stream work time frames, when construction is most feasible due to 
low water flow, most commonly run from July to September, but could be 
as narrow as July 15 to August 15, or just 1 month. According to time 
frame information provided by district and forest offices for 56 
completed culvert projects, construction is the least time-consuming 
phase of a project, ranging from a low of 4 weeks to a high of 61 
weeks to complete, for an average of about 10 weeks. 

According to BLM and Forest Service officials, the minimum time 
necessary to complete a barrier culvert project, if all phases of the 
project are completed in the shortest possible time frame, is about 1 
year. However, due to the factors discussed above, projects are more 
likely to take over a year to complete. The consequences of a delay 
caused by any one of the factors have a cascading effect on the 
project completion date. For example, according to agency officials, 
they generally begin a project by initiating the clearance and permit 
process and collecting some preliminary engineering information. 
However, if project clearances are not obtained or imminent by March 
when project funding decisions are made, construction may be put off 
to the next year, rather than committing funds to a project that may 
not be ready for implementation within the seasonal time frames. 
Similarly, project clearances may be completed timely, but the project 
may be delayed if an engineer with fish passage design experience is 
not available. And, if all phases of a project, including construction 
contracts, are not in place in time to complete construction within 
the state-mandated stream construction time frames, the project must 
be put off until the next season. According to the information 
provided by district and forest offices for 56 projects, the total 
time to complete a project ranged from a low of 16 weeks to a high of 
186 weeks, for an average of 60 weeks. 

Ultimate Effectiveness of Agency Efforts to Restore Fish Passage Is 
Largely Unknown Because Completed Projects Are Not Systematically 
Monitored: 

BLM and the Forest Service completed 141 projects to restore fish 
passage for anadromous fish at barrier culverts from fiscal year 1998 
through July 2001 and opened access to an estimated 171 miles of fish 
habitat. However, because neither agency requires systematic 
monitoring of these completed projects, the actual extent of improved 
fish passage is largely unverified. According to agency officials, 
current culvert fish passage design standards are based on scientific 
research that considers such factors as the swimming ability of fish 
at various life stages and the velocity of water. Therefore, the 
officials assume that fish can migrate into the newly accessible 
habitat through culverts built to these standards. Furthermore, agency 
officials cite a lack of funds and available staff as reasons for not 
requiring systematic post-project monitoring. 

While district and forest offices may monitor projects on a limited or 
ad hoc basis, whether both juvenile and adult fish can actually pass 
through the restored culvert or actually inhabit the upstream areas is 
not systematically determined. However, the Oregon and Washington 
state fish passage restoration programs, as well as other local 
efforts, require systematic post-project monitoring to determine the 
most effective methods for improving fish passage under various 
conditions. Without such monitoring, neither the Forest Service nor 
BLM can ensure that the federal moneys expended for improving fish 
passage are actually achieving the intended purpose. 

Forest Service and BLM Do Not Require Post-Project Monitoring: 

As shown in figure 5, BLM reported 68 projects completed to restore 
fish passage for anadromous fish at barrier culverts from fiscal year 
1998 through August 1, 2001, opening access to an estimated 95 miles 
of fish habitat. During the same time frame, the Forest Service 
reported 73 projects completed to restore fish passage for anadromous 
fish at barrier culverts and opened access to an estimated 76 miles of 
fish habitat.

The actual extent of improved fish passage is largely unknown, 
however, because neither agency requires systematic post-project 
monitoring of completed projects. Forest and district offices 
undertake a wide range of activities in and around streams to restore 
aquatic habitat. These activities include eliminating fish passage 
barrier culverts, as well as other activities such as stabilizing 
eroding stream banks, planting vegetation, and placing desirable woody 
debris and boulders into the streams. While each forest and district 
office is required to conduct monitoring of selected restoration 
activities, neither agency specifically requires barrier culvert 
projects be monitored. Therefore, restoration projects selected by 
district and forest offices for monitoring may or may not include 
barrier culvert passage projects. Consequently, the agencies do not 
systematically determine whether fish can actually pass through 
repaired or replaced culverts. Furthermore, while the miles of habitat 
theoretically made accessible to fish is estimated, the extent to 
which fish actually inhabit that stream area is not routinely 
determined. 

BLM and Forest Service officials stated that monitoring all culvert 
fish passage projects would be a costly and time-consuming effort for 
their already limited staff. Therefore, district and forest staff 
stated that culvert project follow-up is generally ad hoc in nature. 
For example, subsequent to project completion, the designing engineer 
will likely look to see if water appears to be flowing through the 
culvert as designed, or the fish biologist that helped plan a project 
may walk up the stream side looking for egg beds to ascertain the 
presence of fish. However, according to agency officials, a 
formalized, comprehensive measurement of results, for example, 
requiring engineers to measure water flows through all completed 
culverts or biologists to count egg beds in every area of a newly 
opened habitat is not feasible at current funding and staffing levels. 
One forest official stated that ideally, every project should have 
monitoring funds included with the project funds to verify 
effectiveness, but funding realities have not made this possible. 

According to BLM and Forest Service officials, in the absence of 
systematic monitoring, they assume that culverts built to current 
standards will allow fish migration into the newly accessible habitat.
Current culvert design standards are based on scientific research that 
considers important factors such as the swimming capabilities of fish 
at various life stages and the velocity of water to guide engineers in 
building culverts that will allow passage of juvenile to adult fish. 
BLM primarily follows the standards published by the Oregon State 
Department of Fish and Wildlife, and the Forest Service follows those 
same Oregon standards or the Washington Department of Fish and 
Wildlife's standards, depending on the project's location. Where 
appropriate, the current standards endorse the use of open bottom 
culverts that simulate natural stream bottoms and slopes and culvert 
widths that adhere to the stream's natural width, mimicking the 
stream's natural features to the greatest extent possible. 

However, even culvert projects built to current standards may not 
necessarily result in improved fish passage. District and forest 
officials characterized culvert fish passage design as an evolving 
area of study. For example, according to federal and state officials, 
retrofitting culverts by adding staggered or perforated panels inside 
to slow down water velocities is a complex design process only 
applicable in limited circumstances. Another area of concern, 
according to Forest Service officials, is the length of culverts 
because questions remain as to how far fish will swim inside a dark 
culvert. Furthermore, during our field visits to completed culvert 
project sites, we observed culverts that, according to agency 
officials, continued to be barriers to fish passage, including a 
retrofitted culvert that did not sufficiently slow water flow, a 
replaced pipe that did not allow juvenile fish passage, and a culvert 
that allowed water to flow under it rather than through it. 

Post-Project Monitoring Could Help Identify the Most Effective Fish 
Passage Restoration Methods: 

Systematic post-project monitoring is a requirement of the Oregon and 
Washington state fish passage restoration efforts on state lands, as 
well as cooperative local programs on other lands within the states 
and has helped these programs to identify ways to enhance the 
effectiveness of fish passage projects. According to an Oregon 
Department of Fish and Wildlife official, in fiscal year 1999 the 
state implemented a protocol for systematically monitoring and 
documenting the results of culvert retrofit projects to improve fish 
passage. The protocol, jointly developed by Oregon's Department of 
Fish and Wildlife and Department of Transportation, requires 
monitoring the movement of water in and around retrofitted culverts to 
determine if fish passage is improved. In the first year of 
implementation, the agencies systematically monitored selected 
culverts retrofitted in 1998 within certain state regions, including 
visual inspections and water velocity measurements taken at different 
times to assess how well the retrofit designs slowed water velocity. 
The monitoring results indicated the retrofit designs, while needing 
some adjustments, improved fish passage by slowing water and reducing 
culvert entry jump heights for fish. According to the state official, 
the agencies are currently developing fish passage monitoring 
protocols for culverts that have been replaced rather than retrofitted. 

The Washington Department of Fish and Wildlife, in partnership with 
the state Department of Transportation, developed and implemented a 
three-level culvert and fish use evaluation procedure for all culvert 
retrofit or replacement projects funded by the state's Fish Passage 
Barrier Removal Program. Agreeing that the best management practice is 
to avoid "walking away" from a fish passage project once construction 
is complete, the agencies are systematically assessing culvert 
projects for design, durability and efficiency; determining if fish 
use the newly available habitat; and troubleshooting problems 
identified. The three-level evaluation involves the following steps: 

* First, fish use before and after project completion is determined, 
and each completed project is evaluated for durability, efficiency, 
and design flaws, which are corrected during the year following 
project completion. The culvert is removed from the monitoring list if 
fish passage is verified and no additional monitoring is required. 

* Second, for culverts where fish passage is not occurring, additional 
monitoring for fish presence is implemented, and if necessary, other 
methods to support fish recovery, including supplementation such as 
planting of hatchery fish, fishing restrictions, or stream habitat 
improvement projects, are implemented. 

* Third, selected culverts are studied to determine the overall impact 
on fish populations. 

Evaluation results as of April 2001 indicated most habitats reclaimed 
through culvert projects were immediately populated by fish; however, 
varied responses on some streams require additional monitoring and 
possibly further enhancement efforts to promote fish recovery. 

In addition to the state monitoring efforts, local fish passage 
restoration plans may also require systematic monitoring of project 
results to ensure they are successful. For example, Oregon's Rogue 
River Basin Fish Access Team, composed of local stakeholders, 
watershed councils, and state and federal agencies (including BLM and 
the Forest Service), has established a basinwide strategic plan to 
cooperatively prioritize fish passage barriers, secure funding for 
projects, implement passage enhancement projects, and monitor the 
success of projects. Specifically, to participate in the program, a 
monitoring plan must be completed for each project before the project 
begins. The monitoring plan must determine whether the project was 
implemented as planned, was effective in solving fish passage 
problems, and contributed to the expanding fish distribution across 
the Rogue River basin. Potential techniques suggested to determine 
effectiveness include spawning and snorkeling (underwater observation) 
surveys. 

As their actions demonstrate, Oregon, Washington, and other entities 
consider systematic monitoring to be an important tool to determine 
the most effective methods for improving fish passage under various 
conditions. The systematic monitoring allows the entities to 
incorporate this knowledge into future restoration planning and 
implementation. Their varied approaches reflect the range of methods 
available for monitoring—that is, monitoring improvements to water 
flow at selected culverts of a specific design type, verifying the 
actual presence of fish in a newly opened habitat, or developing 
monitoring plans for specific projects. While each monitoring approach 
requires a commitment of agency staff and funding to implement, they 
all provide valuable information for targeting future expenditures on 
culvert passage restoration methods that most benefit fish. Oregon and 
Washington's monitoring efforts have helped them to assess the success 
of various culvert passage restoration methods and identified methods 
that require adjustments or further study to determine their 
effectiveness. Without such systematic monitoring programs, neither 
the Forest Service nor BLM can ensure that the federal moneys expended 
for improving fish passage are actually achieving the intended purpose. 

Conclusions: 

BLM and the Forest Service are faced with the daunting task of 
addressing a large backlog of fish passage barrier culverts. Given the 
limited funding available for fish passage projects and the various 
factors that affect the agencies' ability to complete projects 
quickly, eliminating barrier culverts will be a long, costly effort. 
While both agencies are already using culvert assessment information 
to help them prioritize projects, that is just the beginning of the 
barrier elimination process. Ultimately, the culvert projects selected 
for implementation-—whether retrofitting existing culverts, replacing 
culverts, or removing culverts-—must achieve the objective of 
restoring fish passage. Systematic monitoring of completed projects 
would provide the agencies with information to help them identify 
which methods actually work best under various circumstances and 
evidence that their expenditures have actually improved fish passage. 
Although monitoring would divert funding and staff from the 
implementation of culvert passage improvement projects, state 
monitoring programs have demonstrated the value of monitoring to 
assess the effectiveness of barrier culvert projects and to allow 
these entities to incorporate this knowledge into future planning and 
implementation efforts. 

Recommendation for Executive Action: 

To determine whether fish passage restoration projects are achieving 
their intended purpose, we recommend that the Director of BLM and the 
Chief of the Forest Service each develop guidance for systematically 
monitoring completed barrier removal projects. This guidance should 
establish procedures that will allow the agencies to cost-effectively 
measure and document improvements to fish passage. 

Agency Comments: 

We provided the Department of the Interior and the Forest Service with 
a draft of this report for comment prior to issuance. The agencies 
generally agreed with the content of the report and concurred with our 
recommendation for systematic monitoring so long as agency officials 
have the discretion to determine the monitoring approaches and 
methodologies that will most benefit them in planning and implementing 
future fish passage projects. We recognize that the agencies will have 
to exercise discretion in developing this guidance, but they need to 
ensure that they implement a monitoring program that cost-effectively 
measures and documents improvements to fish passage. The agencies also 
provided certain technical clarifications, which we incorporated, as 
appropriate, in the report. Copies of the agencies' comments are 
included as appendixes II and III. 

We conducted our review from March 2001 through October 2001 in
accordance with generally accepted government auditing standards.
Details of our scope and methodology are discussed in appendix IV. 

We are sending copies of this report to the Director of the Bureau of 
Land Management and the Chief of the Forest Service. We will also 
provide copies to others on request. 

If you or your staff have any question about this report, please call 
me at (202) 512-3841. Key contributors to this report are listed in 
appendix V.

[A] According to the Forest Service, the Umpqua, Wallow-Whitman, and 
Colville national forests did not provide estimates because their fish 
passage assessments were not complete.

441 G Street, NW: 
Washington, D.C. 20548: 

Dear Mr. Hill: 

Thank you for the opportunity to respond to the General Accounting 
Office's (GAO) draft report entitled, "Land Management Agencies: 
Restoring Fish Passage Through Culverts on Forest Service and BLM 
Lands in Oregon and Washington Could Take Decades" (GAO-02-136). 

The Department of the Interior concurs with GAO's recommendation that 
the Director of the Bureau of Land Management (BLM) and the Chief of 
the Forest Service each develop guidance for systematically monitoring 
completed barrier removal projects. This guidance should establish 
procedures that will allow the agencies to cost-effectively measure 
and document improvements to fish passage. 

If you have any further questions, please contact Joe Moreau, 
Fisheries Program Lead, BLM Oregon State Office, at 503/952-6418, or 
Rebecca Mack, Management and Program Analyst, BLM Management Systems 
Group, at 202/452-5047.

Dear Mr. Hill: 

Thank you for the opportunity to provide a response to GAO's Draft 
Report, Restoring Fish Passage Culverts on Forest Service and BLM 
Lands in Oregon and Washington Could Take Decades, GA0-02-136. 
Enclosed are the comments to the draft report. These comments include 
those of a general nature pertinent to the draft report as a whole, 
such as setting the context within which the review team was directed 
to operate, as well as specific comments addressing factual errors 
and/or misinterpretations. 

The Forest Service generally agrees with the report's content and 
concurs with its recommendations. We appreciate the time and effort on 
the part of GAO staff to examine this complex program, as well as the 
changes made to the first draft based on our exit conference interview. 

The effectiveness monitoring listed as the primary recommendation in 
the report is necessary to ensure that new fish passage structures, 
and those recently repaired, are in fact operating as intended and 
passing fish at all life stages. We want to point out that monitoring 
to ensure that replacement structures operate as intended is a highly 
technical and complex task and requires substantial investment in time 
and trained personnel in order to arrive at accurate results. We also 
want to point out that there are other aquatic organisms that need to 
be considered when replacing road stream crossings. Designs for 
replacement structures or repair of existing structures should 
accommodate other species as well otherwise the replacement structures 
may become obsolete in a short period. Also, barriers to fish passage 
is a national issue that affects all regions of the nation. It is 
important to keep this in mind when discussing funding alternatives to 
rectify this problem. 

If you have additional questions, please contact the Agency's External 
Audit Liaison, Linda Washington at (202) 205-1560. 

Sincerely,

Appendix IV: Scope and Methodology: 

To determine the number of culverts that may impede fish passage on
BLM and Forest Service lands in Oregon and Washington, we interviewed 
officials and gathered documentation from BLM's Oregon State Office 
and the Forest Service's Region 6 office, both located in Portland, 
Oregon. Specifically, we gathered and analyzed information on the 
number and maintenance status of culverts located in the 10 BLM 
districts under Oregon State Office jurisdiction and the 19 national 
forests under Region 6 jurisdiction and the costs and time frames 
associated with the repair of barrier culverts. We conducted site 
visits at four BLM district offices in Oregon-—Coos Bay, Eugene, 
Medford, and Prineville—-and at nine national forest offices—-
Deschutes, Ochoco, Rogue River, Siskiyou, Siuslaw, Umatilla, and 
Williamette in Oregon; and Gifford Pinchot and Olympic in Washington. 
We met with district and forest office staff and collected information 
on their culvert inventories and assessment and prioritization efforts 
and observed completed and potential culvert restoration projects. 

To identify the factors affecting the agencies' ability to restore 
passage through culverts acting as barriers to fish, we interviewed 
BLM and Forest Service headquarters officials, Oregon State Office and 
Region 6 officials, and district and forest office staff and reviewed 
policies, procedures, and practices for repairing, replacing, or 
removing barrier culverts. We gathered and analyzed funding 
information for 141 anadromous fish passage culvert projects completed 
in Oregon and Washington from fiscal year 1998 through July 2001, 
including the amount and source of funds expended for each project. We 
analyzed detailed time line information for 56 of the 141 projects 
that included complete start and finish dates for the three main 
phases of each project-—federal and state clearances, design and 
engineering, and construction. We interviewed agency officials and 
gathered documentation to identify the factors that affect project 
time frames and to determine how these factors limit the number of 
culvert projects that can be completed annually. 

To determine the results of the agencies' efforts to restore fish 
passage, we gathered and analyzed information on the number of (1) 
culverts repaired, replaced, or removed to improve anadromous fish 
passage and (2) miles of habitat restored from fiscal year 1998 
through August 1, 2001, by district and forest offices under Oregon 
State Office and Region 6 jurisdiction. We interviewed BLM and Forest 
Service headquarters, state and regional office, and district and 
forest office officials and reviewed documentation to determine 
whether regulations, policies, and procedures required systematic 
monitoring of the effectiveness of the culvert restoration projects. 
To identify state efforts to monitor the outcome of fish passage 
projects, we interviewed Oregon and Washington state officials and 
reviewed regulations, policies, and procedures and monitoring reports 
provided by the state agencies with fish passage restoration 
responsibilities. 

We conducted our work from March 2001 through October 2001 in 
accordance with generally accepted government auditing standards.
