The Middle Washita Watershed (HUC 11130303) covers an area of approximately 1,897 square miles in Oklahoma. The area is primarily rural, with agriculture being the dominant land use. The watershed is characterized by a mix of grasslands, croplands, and forests. The hydrology of the watershed is strongly influenced by the Washita River, which is the primary surface water source. Snowfall in the area is typically light, with the average snowpack lasting less than a week. The reservoirs in the watershed are primarily used for water supply and recreation. Interesting climatic facts and trends include an overall increase in precipitation over the past few decades, with more extreme weather events such as flooding and drought becoming more common. There has also been a slight increase in average temperatures, which may be contributing to changes in vegetation and wildlife populations in the area.
