Subject: Missouri River Navigation: Data on Commodity Shipments for 
Four States Served by the Missouri River and Two States Served by Both 
the Missouri and Mississippi Rivers: 

The Missouri River reservoir system is a critical national resource 
that provides a variety of benefits, including navigation, flood 
control, irrigation, hydropower, municipal and industrial water supply, 
recreation, and fish and wildlife habitat. The U.S. Army Corps of 
Engineers (Corps) is responsible for operating the Missouri River 
system to serve these congressionally authorized purposes. Between 1933 
and 1964, the Corps built six dams on the Missouri River to serve the 
water resource needs within the Missouri River basin. The resulting 
reservoirs form a series of lakes from Montana to the South Dakota- 
Nebraska border. The Corps manages the system of dams and reservoirs 
according to the water control plan presented in its Missouri River 
Mainstem Reservoir System Master Water Control Manual, which was first 
published in 1960 and most recently revised in 2006. The master manual 
provides water control criteria for the reservoir system for a spectrum 
of anticipated runoff conditions. Annual operating plans based on these 
criteria provide detailed reservoir regulation for each operating year. 

Four states, Iowa, Nebraska, Kansas, and Missouri, are adjacent to the 
Missouri River and are served by barge and other vessel traffic along 
the river. Two states, Iowa and Missouri, are served by navigation on 
both the Missouri River and the Mississippi River (see figure 1). Both 
private companies and the Corps have conducted navigation activities on 
the Missouri River to and/or from these states. Companies transport 
numerous commodities, such as fertilizer, which is shipped from a port 
of origin to a port of destination, or sand and gravel, which some 
companies mine from the river and then transport to a processing 
facility on shore. In addition, the Corps conducts river maintenance 
and habitat recovery projects, which require the shipment of waterway 
improvement material, such as stone or rock.[Footnote 1] In this 
context, you asked us to determine (1) the annual and total tonnage of 
commodity shipments for each state served by the Missouri River, and 
(2) the comparable tonnage of commodity shipments transported on the 
Mississippi River for states served by both the Missouri and 
Mississippi rivers.

[End of figure] 

To determine the tonnage of commodities transported on the Missouri 
River and the comparable tonnage shipped to and/or from Missouri and 
Iowa on the Mississippi River, we obtained and analyzed data for 
January 1, 1994, through December 31, 2006, from the Corps' Waterborne 
Commerce Statistics Center.[Footnote 2] We obtained the data for 
shipments on the Missouri River with an origin and/or destination in 
Missouri, Iowa, Kansas, or Nebraska. We also obtained data for 
shipments on the Mississippi River with an origin and/or destination in 
Missouri or Iowa, but did not collect or analyze data for shipments 
that passed through the Mississippi River waterways of Missouri or Iowa 
without starting or ending their trips in these states. We defined 
annual tonnage shipped for each state as all tons shipped that 
originate or terminate in a state. For example, if a shipment 
originates in Missouri and terminates in Kansas, that shipment's 
tonnage is counted toward the total for the state of Missouri and the 
state of Kansas. However, shipments that originate and terminate within 
the same state are only counted once. 

For the purposes of our review, we generally aggregate commodities into 
three categories: (1) sand and gravel; (2) other commercial products-- 
which include all manufactured equipment, machinery, and products 
(manufactured equipment); chemicals and related products (chemicals); 
coal, lignite and coal coke, crude material, inedible except fuel 
(crude material); food and farm products; petroleum and petroleum 
products (petroleum); primary manufactured goods; and (3) waterway 
improvement material. According to Corps officials, sand and gravel and 
other commercial products primarily constitute commercial shipments. In 
contrast, we consider waterway improvement material as primarily 
noncommercial shipments, because this material is mainly stone or rock 
transported on behalf of the Corps for river maintenance or habitat 
recovery purposes. 

We assessed the reliability of the data we obtained by interviewing 
Corps officials, determining the Corps' process for collecting and 
reviewing the data, and performing various tests on the data--such as 
comparing a number of source documents submitted by vessel operators to 
data within the Corps' database. We determined that the data were 
sufficiently reliable for the purposes of this review. 

On December 11, 2008, and December 19, 2008, we briefed your offices on 
the results of our review. This report summarizes the information 
presented in those briefings and officially transmits the slides used 
during the briefings in enclosure I. 

Summary: 

Of the total commodity tonnage shipped on the Missouri River between 
1994 and 2006, 83 percent (100,183,464 tons) originated and/or 
terminated in the state of Missouri. For the other states served by 
navigation on the Missouri River, Kansas accounted for 12 percent 
(14,171,543 tons), Nebraska accounted for 3 percent (3,279,355), and 
Iowa accounted for 2 percent (2,578,890) of the tonnage transported. 
Tonnage shipped per year over the 13-year period has ranged between 6.9 
million and 9.7 million tons. 

The majority of the shipments on the Missouri River during this period 
were of sand and gravel, which accounted for 84 percent (about 91.3 
million tons) of the total tonnage shipped. Of this amount, 
approximately 54 percent of the sand and gravel was transported 1 mile 
or less, 31 percent between 2 and 9 miles, and 14 percent was 
transported 10 miles or more. According to Corps officials, the short 
distance traveled is because private companies often mine sand and 
gravel directly from the Missouri River and then ship the material 
short distances to a processing facility on shore. Other commercial 
products accounted for 14 percent of the total tonnage shipped between 
1994 and 2006, including 5.2 million tons in food and farm products, 4 
million tons of chemicals, 3 million tons of petroleum, 2.5 million 
tons of primary manufactured goods, 346,460 tons of crude material, and 
14,663 tons of manufactured equipment. Waterway improvement material, 
with 2.2 million tons, accounted for 2 percent of the total tonnage 
during this period. 

For the two states that are served by both the Missouri and Mississippi 
Rivers, tonnage shipped on the Mississippi River was greater than the 
tonnage shipped on the Missouri River for comparable products. For 
example, 2.8 million tons of food and farm material were shipped to 
and/or from Missouri or Iowa on the Missouri River between 1994 and 
2006. In contrast, 189 million tons of food and farm material were 
shipped to and/or from Missouri or Iowa on the Mississippi River during 
the same period. Sand and gravel was the exception, with about 89 
million tons shipped to and/or from Missouri on the Missouri River, 
compared to about 70 million tons of sand and gravel that were shipped 
to and/or from Missouri on the Mississippi River.

Data on Commodity Shipments for Four States Served by the Missouri 
River and Two States Served by Both the Missouri and Mississippi 
Rivers: 

The Missouri River reservoir system is a critical national resource 
that provides a variety of benefits, including navigation, flood 
control, irrigation, hydropower, municipal and industrial water supply, 
recreation, and fish and wildlife habitat. Iowa, Nebraska, Kansas, and 
Missouri are the four states adjacent to the Missouri River that are 
served by barge and other vessel traffic along the river. Two states, 
Missouri and Iowa, are served by navigation on both the Missouri River 
and the Mississippi River. In this context, you asked us to determine 
(1) the annual and total tonnage of commodity shipments for each state 
served by the Missouri River and (2) the comparable tonnage of 
commodity shipments transported on the Mississippi River for states 
served by both the Missouri and Mississippi rivers. 

Background: 

Between 1933 and 1964, the U.S. Army Corps of Engineers (Corps) built 
six dams on the Missouri River to serve the water resource needs within 
the Missouri River basin. The resulting reservoirs form a series of 
lakes from Montana to the South Dakota-Nebraska border. The Corps 
manages the system of dams and reservoirs according to the water 
control plan presented in its Missouri River Mainstem Reservoir System 
Master Water Control Manual, which was first published in 1960 and most 
recently revised in 2006. The master manual provides water control 
criteria for the reservoir system for a spectrum of anticipated runoff 
conditions. Annual operating plans based on these criteria provide 
detailed reservoir regulation for each operating year. 

Both private companies and the Corps transport commodities on the 
Missouri River. Private companies transport numerous commodities, such 
as fertilizer, which is shipped from a port of origin to a port of 
destination, and sand and gravel, which they often mine from the river 
and then transport to a processing facility on shore. In contrast, the 
Corps conducts river maintenance and habitat recovery projects, which 
require the shipment of waterway improvement material, such as stone or 
rock. The Corps also conducts maintenance activities that result in the 
transport of dredged material. According to Corps officials, the agency 
conducted two dredging projects on the Missouri River between 1994 and 
2006, which resulted in 111,333 cubic yards of dredged material being 
transported on the river. Because the Corps does not track dredged 
material in the same manner as it does other commodity shipments, we 
did not include dredged material shipments in our review. 

Commodities are classified according to the Waterborne Commerce 
Statistics Center Commodity Classification List and reflect the 
hierarchical structure of the Standard International Trade 
Classification Codes. For our review, we generally aggregated 
commodities into 3 categories: (1) sand and gravel; (2) other 
commercial products—including all manufactured equipment, machinery, 
and products (manufactured equipment); chemicals and related products 
(chemicals); coal, lignite and coal coke, crude material, inedible 
except fuel (crude material); food and farm products, petroleum and 
petroleum products (petroleum); and primary manufactured goods; and (3) 
waterway improvement material, such as stone or rock. Sand and gravel 
and other commercial products shipments are considered commercial 
shipments, while waterway improvement material shipments are considered 
noncommercial. 

Scope and Methodology: 

To determine the tonnage of commodities transported on the Missouri 
River and portions of the Mississippi River, we obtained and analyzed 
data from the Corps’ Waterborne Commerce Statistics Center. This data 
is self-reported to the Corps by vessel operating companies engaged in 
transporting goods upon the navigable waters of the United States. We 
obtained the data for January 1, 1994, through December 31, 2006. We 
assessed the reliability of the data and determined that the data were 
sufficiently reliable for the purposes of this review.

Between 1994 and 2006, tonnage shipped to and/or from Missouri was 
relatively consistent over time, peaking in 2001 at about 8.9 million 
tons, and approximately 8 million tons were shipped in 2006, the most 
recent year for which data are available. 

Kansas experienced an increase in tonnage shipped from 2000 to 2001, 
peaking at 2.3 million tons in 2001, and slightly declining to 2 
million tons in 2006. 

Iowa experienced a decrease in tonnage shipped during this time, 
experiencing its highest level of tonnage shipped in 2000 with 343,258 
tons. However, shipments declined from 2001 to 2003, and no shipments 
were reported for the state between 2004 and 2006. 

Similarly, Nebraska had its highest level of tonnage shipped in 1994 at 
617,813 tons, but subsequently tonnage declined to zero in 2005, and 
21,356 tons were shipped in 2006. (See figure 2.)

Note: Annual tonnage shipped for each state is defined as all tons 
shipped that originate or terminate in a state. For example, if a 
shipment originates in Missouri and terminates in Kansas, that 
shipment’s tonnage is counted toward the total for the state of 
Missouri and the state of Kansas. Shipments that originate and 
terminate within the same state are only counted once.

Of the total sand and gravel tonnage shipped between 1994 and 2006, 
about 54 percent were transported 1 mile or less, 26 percent between 2 
and 5 miles, 5 percent between 6 and 9 miles, and about 14 percent 10 
miles or more. According to Corps officials, the short distance 
traveled is because private companies often mine sand and gravel 
directly from the Missouri River and then ship the material short 
distances to a processing facility on shore. (See figure 4.)

Of the total shipments, chemicals accounted for about 46 percent of the 
total, while other commercial products, such as food and farm products, 
accounted for 52 percent. Waterway improvement material accounted for 
about 1 percent of the total tonnage shipped for the state.

Kansas: 

Between 1994 and 2006, barges and other vessels transported 14,171,543 
tons of commodities on the Missouri River to and/or from Kansas. Sand 
and gravel accounted for about 90 percent of the total tonnage shipped, 
while other commercial products, such as petroleum and food and farm 
products, accounted for 10 percent. Waterway improvement material 
accounted for less than 1 percent of total tonnage shipped for the 
state. 

Kansas experienced a significant increase in total tonnage shipped 
between 2000 and 2001. The increase can be attributed to an 88 percent 
increase in sand and gravel tonnage shipped on the river. However, 
while sand and gravel tonnage increased, food and farm products tonnage 
decreased by 96 percent between 1999 and 2004, from 200,166 tons to 
7,444 tons. (See figure 7.)

Nebraska: 

Between 1994 and 2006, barges and other vessels transported 
approximately 3.3 million tons of commodities on the Missouri River to 
and/or from Nebraska. Nearly 47 percent of the total tonnage was food 
and farm products, while other commercial products, such as chemicals, 
accounted for 44 percent. Waterway improvement material accounted for 
approximately 9 percent of the total tonnage shipped. 

The decline in tonnage shipped to and/or from Nebraska can be primarily 
attributed to decreases in other commercial products, such as food and 
farm products and chemicals. The tonnage of food and farm products 
shipped decreased 90 percent during 1994 to 2006, from 220,076 tons to 
21,356 tons. The tonnage of chemicals decreased 85 percent during 1994

Appendix I: Scope and Methodology: 

To determine the tonnage of commodities transported on the Missouri 
River, we obtained and analyzed data from the U.S. Army Corps of 
Engineers’ (Corps) Waterborne Commerce Statistics Center. This data is 
self-reported to the Corps by vessel operating companies engaged in 
transporting goods upon the navigable waters of the United States. We 
obtained data for January 1, 1994, through December 31, 2006, for 
shipments on the Missouri River with an origin and/or destination in 
Missouri, Iowa, Kansas, and Nebraska. 

To determine the comparable tonnage of commodity shipments transported 
on the Mississippi River for states served by both the Missouri River 
and the Mississippi River, we obtained and analyzed commodity shipment 
data from the Corps’ Waterborne Commerce Statistics Center. We obtained 
data for January 1, 1994, through December 31, 2006, for shipments on 
the Mississippi River with an origin and/or destination in Missouri or 
Iowa. In order for the data for the Missouri River and Mississippi 
River to be comparable in methodology, we did not collect or analyze 
data for shipments that passed through the Mississippi River waterways 
of Missouri or Iowa without starting or ending their trips in these 
states. 

Some shipments on the Mississippi River can be grouped into categories 
comparable to the categories of shipments on the Missouri River, and we 
only compared data for those commodity categories that were shipped on 
both rivers. For example, there were shipments of coal, lignite, and 
coal coke on the Mississippi River to and/or from the states of 
Missouri and Iowa between 1994 and 2006, but we do not show these data 
in our comparison analysis because there were no such shipments on the 
Missouri River. Instead, we present these data, along with the rest of 
the data for this report, in Appendices II and III. Furthermore, the 
broad commodity categories may include shipments of varying types of 
products within the same category. For example, the commodity category 
all manufactured equipment, machinery, and products includes products 
such as motor vehicle parts, boats, and machinery specialized for 
particular industries. 

For the purposes of our review, we generally aggregate commodities into 
three categories: (1) sand and gravel; (2) other commercial 
products—which include all manufactured equipment, machinery, and 
products; chemicals and related products; coal, lignite and coal coke; 
crude material, inedible except fuel; food and farm products; petroleum 
and petroleum products; and primary manufactured goods; and (3) 
waterway improvement material. We consider sand and gravel and other 
commercial products as shipments that may serve commercial purposes. We 
consider waterway improvement material as primarily noncommercial, as 
this material is primarily stone or rock transported on behalf of the 
Corps for river maintenance or habitat recovery purposes. In addition, 
the Corps conducts maintenance operations that result in dredged 
material. However, the Corps does not track dredged material in the 
Waterborne Commerce Statistics database. While the Corps does collect 
information on dredging projects in the Dredging Statistics database, 
the information is not comparable with data in the Waterborne Commerce 
Statistics database. As such, we did not include this material in our 
review. 

We assessed the reliability of the data by interviewing Corps officials 
about the data, determining the Corps’ process for collecting and 
reviewing the data, and performing various tests on the data—such as 
comparing a number of source documents submitted by vessel operators to 
data within the Corps’ database. We determined that the data were 
sufficiently reliable for the purposes of this review.

Note: Annual tonnage shipped for each state is defined as all tons 
shipped that originate or terminate in a state. For example, if a 
shipment originates in Missouri and terminates in Kansas, that 
shipment’s tonnage is counted toward the total for the state of 
Missouri and the state of Kansas. Shipments that originate and 
terminate within the same state are only counted once.

Footnotes: 

[1] The Corps also conducts maintenance activities that result in the 
transport of dredged material. According to Corps officials, the agency 
conducted two dredging projects on the Missouri River between 1994 and 
2006, which resulted in 111,333 cubic yards of dredged material being 
transported on the river. Because the Corps does not track dredged 
material in the same manner as it does other commodity shipments, we 
did not include dredged material shipments in our review. 

[2] The primary function of the Waterborne Commerce Statistics Center, 
under the authority of the Rivers & Harbors Act of 1922, is to collect, 
process, distribute, and archive vessel trip and cargo data. This data 
is self-reported to the Corps by vessel operating companies engaged in 
transporting goods upon navigable waters of the United States.
