Yellowstone Headwaters

Watershed Hydrology

The Yellowstone Headwaters Watershed (HUC 10070001) spans over 5,500 square miles and is located in the Rocky Mountains of Wyoming, Montana, and Idaho. The area is known for its unique hydrology, with abundant snowpack and high-elevation lakes and streams that feed into the Yellowstone River. The snowpack in the watershed is critical for providing water to the region, as it melts and replenishes surface water sources during dry months. The watershed also contains several reservoirs that provide irrigation and hydroelectric power. Interesting climatic facts include that the area experiences significant temperature fluctuations throughout the year, with summer highs reaching the 80s and winter lows dipping well below freezing. Additionally, the region is prone to wildfire, which can have a significant impact on the watershed's hydrology and water quality.
