The Cheat Watershed (HUC 05020004) covers approximately 1,339 square miles in West Virginia and Pennsylvania. It is a tributary of the Monongahela River and is primarily forested with some agricultural land. The watershed is characterized by a humid continental climate with warm summers and cold winters. The hydrology of the watershed is influenced by the Appalachian Mountains, which provide a significant source of surface water. The watershed also receives significant amounts of precipitation, which contributes to the high levels of surface water. The watershed is known for its specific snowpack, which is influenced by elevation and temperature. In the winter, the higher elevations receive significant amounts of snow, while the lower elevations receive more rain. There are several reservoirs in the watershed, including the Cheat Lake Reservoir, which was created by impounding the Cheat River. These reservoirs provide important sources of drinking water and recreational opportunities. In recent years, there has been a trend of increasing precipitation and flooding in the watershed. This has led to increased erosion and sedimentation in the rivers and streams, which can have negative impacts on aquatic life. The Cheat Watershed is also affected by acid mine drainage, which can damage water quality and aquatic habitats.
