Hydrologic Assessment of the Blackfeet Reservation, Montana

The Blackfeet Nation seeks an increased scientific understanding of the water resources within the Blackfeet Reservation of northwestern Montana. Hydrologic information is needed in order to make informed water management decisions as the Blackfeet Nation moves forward with implementation of the Blackfeet Water Rights Compact as new water-use projects are initiated and as the Blackfeet Irrigation...

Hydrologic Characterization of Potential Sites for Restored and Constructed Wetlands, Montana

Projects conducted by the Montana Department of Transportation (MDT) sometimes result in unavoidable impacts to wetlands and other aquatic habitats. To compensate for these impacts, MDT mitigates the loss of wetlands by providing replacement wetlands within the watershed.

Determination of channel-morphology characteristics, bankfull discharge, and various design-peak discharges in western Montana

Stream-restoration projects using natural stream designs typically are based on channel configurations that can accommodate a wide range of streamflow and sediment-transport conditions without excessive erosion or deposition. Bankfull discharge is an index of streamflow considered to be closely related to channel shape, size, and slope (channel morphology). Because of the need for more information

Hydrogeologic, geophysical, water-quality, transient-tracer, and flow-model analysis of the ground-water flow system near Dillon, Montana

Hydrogeologic data for the northern Rocky Mountains intermontane basins, Montana

The U.S. Geological Survey began a Regional Aquifer- System Analysis of the Northern Rocky Mountains Intermontane Basins of western Montana and central and central and northern Idaho in 1990 to establish a regional framework of information for aquifers in 54 intermontane basins in an area of about 77,500 square miles. Selected hydrogeologic data have been used as part of this analysis to define th
