Watershed Hydrology

The Yellow Watershed (HUC 03140103) covers an area of approximately 3,600 square miles in northwestern Wyoming and southeastern Montana. The watershed is characterized by a semi-arid climate with a significant amount of snowfall during the winter months. The snowpack in the watershed is particularly important for surface water supply during the dry summer months. The watershed includes several small creeks and streams that flow into the Yellowstone River, which is the primary source of surface water for the area. The reservoirs in the watershed are used for irrigation, power generation, and recreation. Interesting climatic facts about the watershed include its location at the edge of the Rocky Mountains, which creates a diverse landscape of high peaks, deep valleys, and rolling plains. The area is also prone to occasional severe weather events, including thunderstorms, hailstorms, and tornadoes. Recent trends in the watershed indicate a decline in snowpack and earlier snowmelt, which could have significant impacts on water availability in the region. Additionally, increasing temperatures and changes in precipitation patterns may also affect hydrological processes in the watershed.
