Grayson County

Sherman is the county seat of Grayson County. It is part of the Texoma region, with proximity to both Lake Texoma and the Red River. The northern part, which drains into Lake Texoma and the Red River, is characterized by acidic soils of the Post Oak Belt, with loamy or sandy surfaces. The southern areas, which drain to tributaries of the Trinity River, have blackland soils conducive to the growth of trees such as post oak, bois d’arc, elm, and walnut, as well as various types of grasses. Natural resources include limestone, oil and gas, bituminous coal, and sand and gravel. Grayson County is drained principally by Choctaw Creek and its two main tributaries, Post Oak and Iron Ore creeks. The county has an average annual precipitation of thirty-seven inches.

The Eisenhower Birthplace State Historic Site, which is the birthplace of Dwight D. Eisenhower in Denison, was acquired and restored in 1952.
