Denison Dam was finished in 1943. At that time, it was the largest "rolled-earth fill dam" (a kind of dirt) in the world. The dam is named for Denison, Texas which is not far away. The dam's spillway is 640 feet (200 m) above sea level. Water has gotten high enough go into the spillway five times.

Denison Dam is made from 18,800,000 cubic yards (14,400,000 m3) of rolled-earth fill. It also produces 250,000 megawatt hours of electricity per year. The dam holds the Red River back to make Lake Texoma which has 2,616,259 acre-feet (3.227108×109 m3) of water. The lake is used to give water to local towns and cities. The dam has 47 areas for people to have fun. The area around the lake has 80,000 acres (32,000 ha) of land people can hunt on.[2]

Oklahoma State Highway 91 and Texas State Highway 91 cross over the dam.
