This 58-page PDF document from the US Bureau of Land Management assesses the potential impacts of coalbed methane development on water resources in Montana's Powder River Basin. The study explores the regional hydrogeologic setting, as well as using computer modeling to forecast anticipated impacts to the local groundwater and surface water resources. Groundwater issues addressed include reduction in hydrostatic head in coal aquifers, quantities of produced water and disposal options, impacts to alluvial aquifers and ground-water recovery potential. Maps, tables, hydrograms and 10-year and 20-year projections are also included.
