Upper Pecos-Long Arroyo

Watershed Hydrology

The Upper Pecos-Long Arroyo Watershed (HUC 13060007) is located in northern New Mexico and covers an area of approximately 1,049 square miles. The watershed is characterized by steep slopes, high elevations, and a semi-arid climate, with average annual precipitation ranging from 20 to 30 inches. The area is also known for its unique snowpack patterns, which are heavily influenced by the surrounding mountain ranges. The hydrology of the watershed is dominated by the Pecos River, which flows through the center of the region and provides a significant source of surface water for the surrounding communities. The watershed is also home to several small reservoirs, which are used for irrigation, recreation, and wildlife habitat. Interesting climactic facts and trends include the region's susceptibility to drought, which has led to significant water shortages in recent years. Additionally, climate change is expected to have a significant impact on the watershed, with models predicting increased temperatures and changes in precipitation patterns that could further strain water resources in the area.
