The Santa Fe Watershed (HUC 03110206) covers an area of approximately 4,080 square kilometers in northern New Mexico. The area is characterized by a high-elevation, arid climate with an average annual precipitation of 520 millimeters, with much of it falling as snow in the winter months. The watershed is home to several important rivers and streams, including the Santa Fe River and the Rio Nambe. These waterways provide critical habitat for a range of aquatic species, including the Rio Grande cutthroat trout. Despite its arid climate, the watershed is heavily influenced by snowpack, which plays a critical role in determining the timing and quantity of surface water flows. In fact, the area is known for its "monsoon season," which typically begins in July and brings heavy rainfall and thunderstorms. In recent years, the watershed has faced several challenges related to water quality and availability, including concerns about contaminants such as arsenic and fluoride in surface water supplies. Additionally, climate change is expected to have significant impacts on the hydrology of the region, including changes in snowpack, streamflow timing and quantity, and overall water availability.
