A wide range of public and commercial recreation facilities including full service marinas, camping and motel accommodations are located along the shoreline. The City of Houston owns two-thirds of the water rights of the lake, with the other 1/3 remaining under control of the TRA.

The Lake

The earthfill dam has a concrete spillway and was designed by Brown and Root, Incorporated (the predecessor to the modern-day KBR

). The dam has a spillway crest elevation of 99 feet (30 m) above mean sea level. The average base width of the Dam's earthen embankment is 310 feet (94 m) wide. The spillway is designed and constructed to pass flows of three times the maximum-recorded flow of the river at this site.

Lake Livingston has a surface area of 83,000 acres (360 km²) and impounds 1750000 acre.ft of water at its normal pool elevation of 131 feet (40 m) above mean sea level. The average depth of the lake is 23 feet (7 m) with a maximum depth of 90 feet (27 m). Lake Livingston has more than 450 miles (724.2 km) of shoreline extending into San Jacinto, Polk, Walker

, and Trinity Counties.

Flood control

Lake Livingston was built with no flood control capabilities/flood storage capabilities, and because of this all water entering the lake whether it be from rainfall or inflow, must exit the lake as increase intake occurs. Flow through the dam is controlled by 12 tainter gates in a concrete and steel spillway that has an average depth of 55 feet. Operations of the spillway mirror river flows, so within a relative short period of time of increase of river flow discharge is increased, and vice versa.

Over the course of the repair movement of 72,215 tons of 32 inch rock in 3,183 truckloads and 15,808 tons of eight-inch (200 mm) bedding rock in 687 truckloads was required. The rock was mined from a quarry in Navarro County near Corsicana. Work was largely completed by April 28, 2006, but due to a severe drought in 2006, the lake's regular pool level was not reached until the spring of 2007.
