Possum Kingdom Lake is a reservoir located in Palo Pinto County, Texas. It was created in 1941 by the Brazos River Authority to provide hydroelectric power to the area. The lake covers an area of 17,000 acres and has a shoreline of around 310 miles. The hydrology of the lake is maintained by inflows from the Brazos River and several small creeks.

The lake is a popular recreational spot, with activities such as fishing, boating, and camping. It is home to several species of fish, including catfish, bass, and crappie. The lake also provides water for agricultural purposes, such as irrigation and livestock watering. The area around the lake is also known for its hunting and wildlife viewing opportunities.

The flow of the lake is regulated by the Brazos River Authority, with water levels fluctuating depending on rainfall and snowpack conditions. Snowpack providers such as the National Oceanic and Atmospheric Administration (NOAA) and the Natural Resources Conservation Service (NRCS) monitor the snowpack levels in the area to determine the potential impact on water supply. Overall, Possum Kingdom Lake plays a significant role in the hydrology, agriculture, and recreation of the region.
