In accordance with the National Environmental Policy Act and implementing regulations, an Environmental Assessment EA has been prepared and integrated into the 2007 Master Plan Update for the Garrison DamLake Sakakawea Project in North Dakota. The updated Master Plan will provide guidance for stewardship of natural resources and management for long-term public access to, and use of, the natural resources of Lake Sakakawea. The Master Plan provides a comprehensive description of the project, a discussion of factors influencing resource management and development, an identification and discussion of special problems, a synopsis of public involvement and input to the planning process, descriptions of past and present development and resource objectives and needs. The Master Plan update concerns only areas under the present ownership of the Corps of Engineers Corps. It does not address or relate to Corps management policies that govern Lake Sakakawea water levels and management. Two alternatives and their corresponding impacts associated with this Federal action have been analyzed for this project. The two alternatives are the No Action and the proposed Master Plan update. Resource categories that were evaluated included, but were not necessarily limited to, land allocations and land use classifications, visual aesthetics, mineral resources, terrestrial wildlife, associated aquatic habitats and species, threatened and endangered species, invasive plants and aquatic nuisance specs, cultural resources, recreation, water quality, and socioeconomics. Under the No Action alternative, the 1978 Master Plan would not be updated. The alternative of no action is assumed to result in diminished success in pursuing resource objectives of the Garrison DamLake Sakakawea project and, as a result, was eliminated from further consideration.
