Abstract:

The Omaha District District of the U.S. Army Corps of Engineers Corps is implementing a Water Quality Management Program WQMP as part of the operation and maintenance activities associated with managing the Corps civil works projects in the District. The WQMP addresses surface water quality management issues and adheres to the guidance and requirements specified in the Corps Engineering Regulation ER 1110-2-8154, Water Quality and Environmental Management for Corps Civil Works Projects USACE, 1995. A periodic report of water quality conditions in the Missouri River Mainstem System Mainstem System is currently being prepared annually to document and assess water quality conditions occurring at the Corps Mainstem System projects in the District. The report describes existing water quality conditions and identifies any evident surface water quality management concerns. The annual reporting of Mainstem System project water quality conditions is done to facilitate water quality management decisions regarding the operation and regulation of the Mainstem System projects. The following general water quality concerns have been identified for civil works projects in the District 1 reservoir eutrophication and hypolimnetic dissolved oxygen depletion, 2 sedimentation, 3 shoreline erosion, 4 bioaccumulation of contaminants in aquatic organisms, 5 occurrence of pesticides, and 6 urbanization. The District has identified eight priority issues for water quality management these priority issues and their relative ranking are listed in Table 1-2. Table 1-3 summarizes TMDL considerations, fish consumption advisories, and other water quality management issues applicable to the Mainstem System projects.
