Fish and Wildlife Service, Texas.
Hagerman National Wildlife Refuge was established in 1946 to provide habitat for migratory birds, wildlife, and plants native to the area. The 11,320-acre refuge is an overlay of the Big Mineral Arm of Lake Texoma. Shallow marshes, creeks, bottomland hardwoods, forested uplands and grasslands, and managed farm fields provide habitat for more than 300 species of birds and many varieties of wildlife. Western areas of the refuge are within the unique Cross Timbers Ecoregion which features stunted, gnarly-shaped post oak and blackjack oak trees that are much older than they appear.
Around 230,000 visitors annually come to the refuge for wildlife observation, photography, hiking, fishing, hunting, and interpretive and educational programs.
