Water Resources: Corps of Engineers Management of 1986 Flooding in Northeastern Oklahoma

In response to a congressional request, GAO reviewed the Corps of Engineers' efforts to deal with the flooding that occurred in September and October of 1986 in northeastern Oklahoma to determine: (1) whether the Corps released water from its reservoirs in accordance with its operating procedures; (2) whether a modification to the Arkansas River Basin Operating Plan adversely affected the flooding; (3) the Corps' weather and flooding forecasting responsibilities; (4) problems with river gauges; (5) how the Corps communicated water release information to state and local entities; and (6) how the Corps conducted post-flood evaluations.
