The Popo Agie Watershed, located in Wyoming, covers an area of approximately 600 square miles. Hydrologically, the watershed is characterized by its steep slopes, rugged terrain, and high precipitation, which results in frequent flooding events. The watershed receives significant snowfall during the winter months, which contributes to its surface water supply. The snowpack in the area is closely monitored and serves as an important source of information for predicting water availability during the summer months. The watershed is home to several reservoirs, which store water for irrigation, municipal use, and recreational activities. The water in these reservoirs is monitored for various constituents, including nutrients, metals, and organic compounds. Recent climate trends in the region indicate an increase in temperature and a decrease in precipitation, which may have significant impacts on the watershed's hydrology and water resources management in the future.
