The Upper Prairie Dog Town Fork Red Watershed (HUC 11120103) covers an area of approximately 2,750 square miles in the Texas Panhandle. The watershed is characterized by rolling plains and significant topographic relief. The hydrology of the watershed is dominated by the Prairie Dog Town Fork Red River and its tributaries. The watershed experiences a semi-arid climate, with hot summers and cold winters, and receives an average of 20 inches of precipitation per year, with most of it falling in the form of snow or rain. Snowpack in the watershed is variable but typically does not accumulate to significant depths. Surface water resources in the watershed are limited, with most of the water used for irrigation purposes. Reservoirs in the watershed are primarily used for flood control and recreation. The most notable reservoir in the watershed is the Lake Meredith National Recreation Area. The climate in the watershed has been trending towards increased temperatures and decreased precipitation, leading to concerns about drought conditions and water availability in the future.
