Region 2 Lower Red-Sulphur-Cypress Flood Planning Region

Twenty-one (21) major lakes and reservoirs are found in this region in the northeast corner of the state, which borders Oklahoma to the north and Louisiana to the east. After leaving Lake Texoma, the lower Red River is fed by numerous creeks and tributaries on its way to the Louisiana border. The Sulphur River and its tributaries run from west to east where it serves as the border between Bowie and Cass counties before entering Louisiana. Cypress Creek (sometimes called Cypress Bayou) flows across this region to its confluence with the Red River in Louisiana. Along the way, it flows through Caddo Lake, one of the state's only natural lakes.
