Excerpts from the report: This is a report of a study of problems, needs, potentials, and opportunities for the development and use of water and related land resources in the Wind-Bighorn-Clarks Fork River Basin. The basin includes the hydrologic drainages of the Wind River, Bighorn River, Shoshone River, Clarks Fork River, Stillwater River, Little Bighorn River, all of their tributaries, and some south-side tributaries of the Yellowstone River between Columbus and Bighorn, Montana. The total area of the basin is 18,167,990 acres or about 28,390 square miles. About 72 percent of the area is in Wyoming and 28 percent in Montana. The Yellowstone River Compact of 1950 allocates the interstate waters between Wyoming and Montana except those in the Little Bighorn River. This is a report of a survey of the water and related land resources of the basin. The objective of this study is to promote a coordinated, orderly program for the conservation, management, use, and development of these resources. Opportunities are identified for programs and projects which can be administered or assisted by agencies of the U, S. Department of Agriculture. Information available in this report will be helpful in the development of Montana and Wyoming State Water Plans. State, local government, and private agencies involved in developing water and related land resources of the basin should find useful information in this report.
