Water-Quality and Fish Tissue Data from Boneau and Williamson Reservoirs, Chippewa Cree Tribe Rocky Boy's Reservation, Box Elder, Montana, May - September 2022
Water and fish tissue were sampled in Boneau and Williamson reservoirs, Rocky Boy's Reservation, near Box Elder, Montana. The sampling was part of a program funded by the U.S. Environmental Protection Agency. Sampling was completed by the U.S. Geological Survey in cooperation with the Chippewa Cree Tribe, to characterize background water quality and mercury in fish tissue within the tribal lands.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. - Data

U.S. Geological Survey and Blackfeet Water Department Hydrologic Assessment of the Blackfeet Indian Reservation, Montana
The Blackfeet Nation seeks an increased scientific understanding of the water resources within the Blackfeet Indian Reservation of northwestern Montana. Hydrologic information is needed to better inform water-management decisions as the Blackfeet Nation implements the Blackfeet Water Rights Compact, initiates new water-use projects, and improves the Blackfeet Irrigation Project.The U.S. GeologicalAuthorsSean M. Lawlor, Rodney R. Caldwell, Timothy T. Bartos, Brett PriceDetermination 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 informationAuthorsSean M.

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.
