Blacks Fork

Watershed Hydrology

The Blacks Fork Watershed covers an area of approximately 782 square miles in northeastern Utah and southwestern Wyoming. It is a part of the larger Green River Basin and is characterized by high-elevation snowpack, which provides critical water supplies for downstream agricultural and urban use. The watershed is home to several large reservoirs, including Flaming Gorge and Fontenelle, which are important sources of hydropower and recreation. Climate trends in the Blacks Fork Watershed indicate increasing temperatures and more frequent drought conditions, which have significant implications for water availability and ecosystem health. Additionally, the watershed is subject to periodic flash floods and debris flows, which can have significant impacts on infrastructure and human safety. Overall, the Blacks Fork Watershed is an important region for water resources management, ecological conservation, and outdoor recreation. Ongoing research and monitoring efforts will be critical to understanding and addressing the complex challenges facing this unique and dynamic ecosystem.
