I I I I I I I I I I I U I) 1 t' 3 i ( .. tl, Instream Flow Needs The instream flows needed to support instream functional uses for navi- gation, recreation, hydroelectric power and water quality were not furnished for the Modified Central Case. Flows needed to maintain stream fisheries and wildlife and for recreation purposes, except for some streams in Colorado and Montana, have not been established for streams in the Missouri REgion. Colorado has established laws governing instream flows for fisheries; Montana has established protective status for 10 trout streams; and North Dakota has esta- blished protective status for one stream. Legal designation of streamflows for fish and wildlife is very contentious in the Missouri Region. The U.S. Fish and Wildlife Service furnished approximations of instream flows by month and annual mean discharges at the outflow points of each ASA. In furnishing these esti- mates, the U.S. Fish and Wildlife Service recognized that expressing instream flow estimates of aquatic life within the fluvial waters of a basin as large as the ASA's at the outflow point only is biologically unsound. The instream flow approximations furnished were not utilized in the regional assessment. Conservation and Management Needs (Non-Volumetric Requirements) Very little data or information were furnished for the MCC concerning present and future requirements for water and related land resources by functional uses which do not involve withdrawal or consumptive use of water or which do not occur instream. Flood damage data furnished is not repro- duced here since data by states are shown under the State/Regional Future. Information applicable to the Missouri Region concerning recreation problem issues, endangered SPecies, wilderness areas, and areas of critical environ- mental concern was utilized in the regional assessment to the extent it was considered useful.
