Physical Habitat Analysis of Missouri River Main Stem Reservoir Tailwaters Using the Riverine Community Habitat Assessment and Restoration Concept (RCHARC)
2006
Nestler, John M. | Schneider, L. T.
Increased demand for water resources in the main stem Missouri River that is regulated by Corps of Engineers' dams has intensified the conflict between the economic benefits of stream regulation and the need to protect lotic ecosystems. Impact assessment methodologies that are quantifiable, repeatable, acceptable, and defensible are required by the U.S. Army Engineer Division, Missouri River, to mediate conflicts between water resources development and natural resource preservation. The Riverine Community Habitat Assessment and Restoration Concept (RCHARC) provides fish habitat information that can be used in trade-off analyses of competing water uses. This report presents an application of the RCHARC to the tailwaters of Gavins Point Dam, Fort Randall Dam, Garrison Dam, and Fort Peck Dam to assess the effects of different release alternatives on habitat for native riverine warmwater fishes. Application of the RCHARC to the regulated Missouri River requires four steps.
