Denison Landmark

Completed 1944, the Denison Dam impounds the Red River Basin forming Lake Texoma - the second largest lake in Texas and the eleventh largest reservoir in capacity in the United States. The Denison Dam is located on the Red River between Texas and Oklahoma about 726 miles from the mouth of the Red River, or sometimes known as the Red River of the South and is managed by the US Corps of Engineers. When Lake Texoma began filling up, it changed the landscape considerably, forcing the relocation of railroads, highways, utilities, and cemeteries. The town of Preston, Texas, also known as Preston Bend was completely covered. You can drive across the Denison Dam on Hwy 91 and take in beautiful views of both Lake Texoma and the Red River and surrounding areas.
