The Colorado Headwaters Watershed (HUC 14010001) covers an area of approximately 6,000 square miles in Colorado. It is the primary source of water for the Colorado River, which supplies water to millions of people in the Western US. The watershed is characterized by high altitude, steep terrain, and a semi-arid climate. It receives significant amounts of snowfall in the winter, which contributes to its snowpack, a critical source of water for the region. The watershed also has several reservoirs that store water for use during dry periods. The water in the reservoirs contains dissolved minerals, which can affect water quality. In recent years, the watershed has experienced a decline in snowpack due to climate change. This trend has significant implications for water availability and management in the region.
