The Rock Watershed, also known as HUC 16040106, covers an area of approximately 4,500 square miles and is located in northern Utah. The watershed is fed by snowmelt and precipitation, which flow into the Weber River and ultimately into the Great Salt Lake. The watershed is known for its abundant snowpack, which serves as a crucial source of water for the region. The snowpack is monitored closely by water managers, as changes in snow accumulation and melt patterns can have significant impacts on water availability. Surface water in the Rock Watershed is primarily used for irrigation and municipal purposes, with several reservoirs located throughout the region. These reservoirs store water for use during times of low flow and drought. Climatically, the Rock Watershed experiences hot, dry summers and cold winters with heavy snowfall. In recent years, the region has seen an increase in temperatures and a decrease in snowpack, which has raised concerns about water availability in the future.
