The Buffalo Watershed (HUC 08060206) covers an area of approximately 3,870 square miles in Wyoming and Montana. The watershed is largely dominated by high elevation, mountainous terrain and is home to a diverse range of hydrological features, including alpine lakes, wetlands, and mountain streams. The watershed experiences a range of climatic conditions, with average annual precipitation ranging from 10 to 40 inches. The snowpack in the Buffalo Watershed is an essential source of water, with the majority of the water supply coming from snowmelt during the spring and early summer months. The snowpack is highly variable, with significant year-to-year differences in snowfall amounts and timing. Surface water in the watershed is primarily sourced from mountain streams, which flow into the Tongue River and eventually into the Yellowstone River. The Tongue River Reservoir is the largest reservoir in the watershed, and is primarily used for irrigation and recreation. Climatic trends in the Buffalo Watershed include an overall increase in temperature and a decrease in snowpack over the last several decades. These changes are expected to have significant impacts on the hydrology of the watershed, including reduced water availability and increased risk of wildfire.
