The Piedra Watershed (HUC 14080102) is located in southwestern Colorado and covers an area of approximately 562 square miles. The watershed is characterized by steep mountainous terrain and is heavily influenced by snowpack accumulation, which typically peaks in March and April. The watershed provides important surface water resources for irrigation, domestic use, and recreation. The main reservoir in the watershed is the Navajo Reservoir, which is used for water storage and hydroelectric power generation. The water quality of the watershed is generally good, with some concerns about sedimentation and nutrient loading. In recent years, the area has experienced warmer temperatures and changes in precipitation patterns, which have contributed to reduced snowpack and earlier snowmelt. These trends may have significant implications for water availability and management in the future.
