Lake Bob Sandlin is a 9,400-acre reservoir located in northeastern Texas near Mount Pleasant. The lake was created in 1979 by the construction of a dam on the Cypress Creek, a tributary of the Sabine River. The lake is primarily used for recreational purposes, such as fishing, boating, and camping. The hydrology of the lake is maintained by the Sabine River Authority, which manages the lake’s water level and quality. The lake receives its water from the Cypress Creek watershed, as well as from surface runoff and precipitation. There are several surface flow and snowpack providers that contribute to the lake’s water supply, including the Cypress Creek, Big Creek, and Little Cypress Creek watersheds. The lake also supports local agriculture, including livestock grazing and crop production. Overall, Lake Bob Sandlin is an important natural resource for the surrounding communities and provides a variety of benefits for both residents and visitors.
