Title
Accessing Clark Fork Basin ground-water information from the Ground-Water Assessment Program, Montana Bureau of Mines and Geology, Butte
Abstract
Field data from about 3,000 wells within the Clark Fork River basin are available from the Montana Bureau of Mines and Geology (MBMG) through the work of the Ground-Water Assessment Program. These data have been systematically collected during Ground-Water Characterization studies completed in the Flathead Lake Study Area (Flathead and Lake counties, 1995-1998), Lolo-Bitterroot Study Area (Mineral, Missoula, and Ravalli counties, 1997-2000), and Upper Clark Fork Study Area (Granite, Powell, Deer Lodge, and Silver Bow counties, 2000-2003). Within each study area, information was collected at approximately 1,000 wells and included: on–site measurements of pH, temperature, specific conductivity, water-level, and latitude and longitude. Additionally, about 25% of the visited wells were sampled for major cations, anions, nitrate, and trace metals (with a small portion of these analyzed for tritium concentration). Ten percent of all wells visited also had monthly water levels collected for 3 years. All information was collected using standardized repeatable methods and has been internally reviewed for consistency and accuracy.
The MBMG has published interpretative maps and a final report for the Flathead Lake Study Area that outlines and evaluates: the geologic framework of aquifers and confining units, depths to and thickness of hydrogeologic units, ground-water flow systems and water quality, and water-level changes. Maps for the Lolo-Bitterroot Study Area are nearing review. Field data, water-quality data, and completed maps are available to download through the Ground-Water Information Center’s website. The field and lab data can be easily downloaded, copied directly into an excel spreadsheet, and used with any geographical information system software. To purchase a hardcopy of maps and reports contact our office (406.496.4174) or log onto MT Bureau of Mines & Geology web site.
