The Upper Pecos Black Watershed (HUC 13060011) is located in north-central New Mexico, covering approximately 679 square miles. The hydrology of the watershed is dominated by the Pecos River, which originates in the Sangre de Cristo Mountains and flows through the watershed. The watershed receives an average annual precipitation of 20-25 inches, with much of it falling as snow in the winter months. The watershed also contains several reservoirs, including the 1,200-acre Cowles Reservoir, which is used for recreation and water supply. The watershed is known for its diverse wildlife, including elk, mule deer, and black bear. In recent years, the area has experienced increasing temperatures and decreased snowpack, which has led to concerns about water availability in the future.
