Atmospheric warming is driving a shift in precipitation from snow to rain, changing precipitation intensity and seasonality, and increasing atmospheric demand for moisture in mountain river watersheds across the western United States. These changes will likely alter the timing and quantity of streamflow in rivers draining from the mountains. The Tongue River flows from the Bighorn mountains in north-central Wyoming into Montana through alpine meadows to sagebrush steppe, prior to its confluence with the Yellowstone River at Miles City, MT. The Tongue River is a little-studied river with hydrologic conditions (e.g. water flow, temperature, quantity) relevant to Tribal water rights and management, fisheries, interstate water rights, [...]
