Daily Streamflow Data of Swift Reservoir Outflow and Selected Diversions from Birch Creek, Pondera County, Montana, January 2020 through December 2022

In 2019, the U.S. Geological Survey (USGS), in cooperation with the Blackfeet Water Department, initiated a multi-year hydrologic investigation of the Blackfeet Indian Reservation. The investigation was designed to increase understanding of the water resources of the Blackfeet Indian Reservation including Birch Creek which forms the southern boundary of the reservation. Streamflow is controlled in the headwaters of Birch Creek through the outflow from Swift Reservoir at Swift Dam. The data included in this data release was provided by the Pondera County Canal and Reservoir Company (PCCRC) and includes Swift Reservoir outflow daily streamflow values and daily streamflow values for three downstream diversions from Birch Creek including the B Canal Diversion, the Kingsbury Diversion, and the Ryan Lauffer Diversion for calendar years 2020-2022.
