The average size spotted bass measures a respectable 12 to 14 inches. The cool, well-oxygenated water of Possum Kingdom supports a quality striped bass population. Although there is evidence of sporadic natural reproduction, it has little influence on abundance and the fishery is sustained almost entirely by annual fingerling stocking. An ample supply of gizzard and threadfin shad allows stripers to reach trophy proportions. The lake record striper weighed 31.6 pounds.
Sand bass are fairly abundant and provide exciting action, especially during their spring migration.
Some of the best tailrace striper fishing in Texas is found in the Brazos River below the Morris Sheppard Dam. During winter, the Texas Parks and Wildlife Department stocks catchable-size rainbow trout below the dam. The maximum depth is 140 feet, the average is 37 feet. Tributaries include Bee, Brawner, Cedar, Deer, Maloney, Fox Hollow, Ainsworth, Elm and Ramsey creeks. Possum Kingdom Lake was designed to provide flood control, hydroelectric power generation and recreation.
