The Logan watershed (HUC 10220004) occupies a total land area of approximately 1,770 square miles in the state of Utah. The watershed is characterized by a semi-arid climate, which is influenced by the Rocky Mountains to the east. The hydrology of the watershed is dominated by the Logan River, which is fed by numerous tributaries, and is the primary source of surface water for the region. The watershed receives significant snowfall during the winter months, which contributes to the snowpack that feeds the river during the spring and summer. The reservoirs in the watershed are primarily used for irrigation and recreation. Interesting climatic trends in the region include increasing temperatures and decreasing snowpack, which are attributed to climate change. The area is also prone to flash floods during heavy rainfall events, which can impact the local communities and infrastructure.
