Missouri River Basin Master Manual The Missouri River Basin Master Manual is a comprehensive operational plan guiding reservoir operations and river management for the Missouri River system across the United States. It coordinates actions among federal agencies such as the United States Army Corps of Engineers, the Bureau of Reclamation, and the United States Fish and Wildlife Service while interfacing with federal laws like the Water Resources Development Act of 1974 and the National Environmental Policy Act. The Manual shapes flood control, navigation, water supply, hydropower, and ecosystem restoration activities across multiple states and tribal nations.
Overview and Purpose
The Master Manual establishes operational objectives and rule curves for 11 mainstem reservoirs administered by the United States Army Corps of Engineers at the direction of the Missouri River Basin Project. It balances authorized purposes under statutes such as the Flood Control Act of 1944, the Rivers and Harbors Act of 1899, and the Endangered Species Act of 1973 to meet authorized project purposes including navigation to the Port of Kansas City, flood risk reduction for communities like Omaha, Nebraska and Bismarck, North Dakota, hydropower generation at facilities like Gavins Point Dam, and municipal water supplies for jurisdictions exemplified by Sioux Falls, South Dakota. The Manual provides procedures for seasonal operations, drought response, and coordination with interstate compacts such as the Missouri River Basin Compact.
History and Development
Development of the Master Manual traces to major 20th-century initiatives including the Pick-Sloan Missouri Basin Program and postwar construction of mainstem dams such as Fort Peck Dam and Garrison Dam. Key legal and policy milestones shaping the Manual include litigation and settlements involving the Cheyenne River Sioux Tribe, the Crow Tribe, and other federally recognized tribal nations, as well as federal reviews prompted by decisions from the United States District Court for the District of Nebraska and guidance from the United States Department of the Interior. The 1990s and 2000s saw environmental and stakeholder-driven processes invoking the National Environmental Policy Act of 1969 and environmental impact statements prepared by the U.S. Army Corps of Engineers, Northwestern Division culminating in the promulgation of the current Manual by the Assistant Secretary of the Army (Civil Works).
Governance and Stakeholders
Governance of the Manual involves coordination among executive agencies including the United States Army Corps of Engineers, the Bureau of Reclamation, the Environmental Protection Agency, and the United States Fish and Wildlife Service. Congressional oversight from committees such as the United States House Committee on Transportation and Infrastructure and the United States Senate Committee on Environment and Public Works has influenced amendments. Stakeholders include state governments of Montana, North Dakota, South Dakota, Nebraska, Iowa, Kansas, and Missouri; tribal governments including the Standing Rock Sioux Tribe and the Mandan, Hidatsa and Arikara Nation; river users such as the Port of Omaha and commercial carriers; conservation groups like The Nature Conservancy and National Audubon Society; and municipal water providers and agricultural associations including the National Cattlemen's Beef Association and state departments of natural resources.
Operational Policies and Procedures
Operational policies codified in the Manual set reservoir rule curves, flood control diagrams, and seasonal release schedules implemented at projects such as Fort Randall Dam and Big Bend Dam. Procedures specify coordination with forecasting agencies like the National Oceanic and Atmospheric Administration and the National Weather Service for hydrologic modeling, and use models developed by the Hydrologic Engineering Center and the U.S. Geological Survey. Protocols address water allocation during droughts under interstate agreements such as the Missouri River Basin Compact and procedures for emergency operations referencing the Federal Emergency Management Agency coordination. The Manual prescribes procedures for minimum flows to support navigation to the Harrison County, Missouri reach and for hydropower dispatch at Lewis and Clark Lake facilities.
Flood Control, Navigation, and Water Supply Management
Flood control operations under the Manual implement authorized storage reservation tiers to attenuate flood peaks impacting metropolitan areas including Kansas City, Missouri and St. Louis, Missouri. Navigation management involves maintaining channel depth for barge traffic along the McClellan-Kerr Arkansas River Navigation System connection points and coordinating with the U.S. Coast Guard for aids to navigation. Water supply policies address municipal and industrial withdrawals for cities such as Lincoln, Nebraska and agricultural irrigation interests represented by organizations like the Irrigation Association. The Manual integrates hydropower objectives serving regional transmission operators including Midcontinent Independent System Operator and coordinates with stakeholders such as the South Dakota Game, Fish and Parks.
Environmental and Ecological Considerations
The Manual incorporates measures to protect species listed under the Endangered Species Act of 1973 including the Pallid Sturgeon and federally designated critical habitat in reaches near Fort Peck Lake. It directs flow regimes and habitat restoration projects to support migratory birds at the Big Muddy National Fish and Wildlife Refuge and to improve conditions for native fish monitored by the U.S. Fish and Wildlife Service and U.S. Geological Survey research programs. Conservation partners such as Ducks Unlimited and academic institutions like University of Missouri and South Dakota State University participate in monitoring. Environmental reviews engage the Council on Environmental Quality processes and consider climate projections from the Intergovernmental Panel on Climate Change in scenario planning.
Implementation, Monitoring, and Revisions
Implementation is overseen by Corps district offices including the Omaha District and the Kansas City District, with monitoring by agencies such as the U.S. Geological Survey and reporting to Congress through entities like the Congressional Research Service. Adaptive management frameworks in the Manual call for periodic review, stakeholder collaboration forums including the Missouri River Recovery Implementation Committee, and formal revisions informed by litigation outcomes from courts such as the Eighth Circuit Court of Appeals and by policies from the Department of the Interior. Revision processes require environmental compliance under the National Environmental Policy Act and often produce supplemental environmental impact statements shaped by inputs from state natural resource agencies and tribal governments.
