Water-resources activities of the U.S. Geological Survey in Montana, October 1985 through September 1986

Water resources programs and activities of the U.S. Geological Survey in Montana consist principally of hydrologic data collection (6 projects); local areal, or statewide hydrologic investigation (12 projects); and research (1 project). The work is supported by direct Federal funding, by transfer of funds from other federal agencies, and by joint funding agreements with state or local agencies. The projects funded for fiscal yr 1986, the operations of the Montana District, water conditions during the preceding year, activities in addition to regular programs, sources of publications and information are described, and reports published or released during the preceding 5 yr are listed.

Hydrogeologic data for selected coal areas, east-central Montana

Hydrogeologic data were collected in selected coal areas of east-central Montana to provide a basis for evaluating the effects of future coal development on the groundwater resources. Inventory records for 916 domestic, stock, public supply, commercial, and test wells are tabulated in the report; the data were collected principally from 1975 through 1976. The locations of the wells are shown on a map at a scale of 1:250,000. Lithologic logs are also included for 149 wells. Chemical analyses of water samples from selected wells consist of 167 samples analyzed for major cations and anions and 24 samples analyzed for miscellaneous constituents.

Geology and water-yielding characteristics of rocks of the northern Powder River basin, southeastern Montana

Numerous and widespread subbituminous and lignite coal deposits occur in the Powder River Basin in southeastern Montana, principally within the Fort Union Formation. Many of the coal beds are less than 250 feet (76.2 m) below land surface and are, therefore, mineable by surface methods. Individual cola beds are commonly 20-30 feet (6.1-9.1 m) thick, but may be as much as 80 feet (24 m). These factors, coupled with the low-sulfur content of the coal, make it attractive as a major energy resource.
