Founded in 1872, the City of Denison was named after Missouri-Kansas-Texas Railroad (MKT) Vice-President George Denison. Today, the MKT, better known as Katy Railroad, has merged with the Union Pacific. From its beginning, the railroad has been an important part of the city. During the 1940's, the Denison economy was strongly impacted by the establishment of Perrin Air Force Base, which began as an Army Air Field. Today, the former air base is under the control of Grayson County and the North Texas Regional Airport, which has both a 9,000 foot and 8,000 foot runway that makes it accessible to aircraft of every size. It serves Denison as a viable private airport and industrial park. While Texoma has little aquatic vegetation, it does offer cover in structures such as rocks/boulders, standing timber, submerged stump beds, channels, rocky bluffs, sandy flats, and rip-rap along Denison Dam and elsewhere. Of the 580 miles of shoreline, there are approximately 9 miles of rip-rap, 50 miles of standing timber, and 50 miles of submersed aquatic vegetation. The remainder is cut banks, sandy beaches, rocky shoreline, and bluffs. A shoreline development ratio of 13.88 indicates an irregular and branched shoreline, which also increases habitat for fish. Free-flowing current in the Red River makes Texoma one of the few lakes in Texas with a self-sustaining population of striped bass, and one of only eight inland freshwater reservoirs worldwide where this species has spawned. A cousin of the white bass, striped bass were first stocked in Lake Texoma by the Oklahoma Department of Wildlife Conservation in 1965. They began spawning in 1974.
