The Upper Little Colorado Watershed (HUC 15020002) covers an area of approximately 2,598 square miles in northeastern Arizona. The region is characterized by high elevations, ranging from 5,000 to 12,000 feet above sea level, and is primarily composed of coniferous forests and grasslands. The watershed contains several major streams, including the Little Colorado River, which flows into the Colorado River, and is heavily influenced by snowmelt and spring precipitation. The area typically experiences a significant snowpack during the winter months, which can lead to spring flooding. Surface water in the watershed is primarily used for agricultural purposes, and the area contains several reservoirs used for irrigation and water storage. Climate trends in the region include increasing temperatures and decreasing precipitation, which could have significant implications for water resources in the future.
