Middle Little Colorado

Watershed Hydrology

The Middle Little Colorado Watershed covers an area of approximately 2,393 square miles and is located in northeastern Arizona. The hydrology of the watershed is characterized by intermittent streams and small tributaries that feed into the Little Colorado River. The watershed is also home to several reservoirs, including the Lyman Reservoir, which provides water for irrigation and recreation. The area experiences a semi-arid climate with hot summers and cold winters. Snowpack in the watershed is variable, with the highest snowpack occurring in the higher elevations of the White Mountains. Surface water in the watershed is limited and often overallocated, leading to conflicts over water use. The reservoirs in the watershed are primarily used for irrigation, with some also used for recreation. The waters of the Middle Little Colorado Watershed contain high levels of dissolved solids, primarily due to natural geological processes. Climatic trends in the watershed indicate an overall increase in temperatures and a decrease in precipitation, which could have significant impacts on water availability and ecosystem health.
