The water level of Inks Lake is usually unaffected by drought and is maintained at a normal level most of the time. During flooding situations, the lake level can rise as the flood waters are passed through Inks Lake to other lakes downstream. The park area has been used for cattle ranching since the mid-1800s. It remained a part of various ranches until the state acquired the land in 1940. Culverts and roads in the park were constructed by the Civilian Conservation Corps from the camp at Longhorn Caverns in the 1930s.
Visitors enjoy camping, backpacking, hiking, and golf.
