Table Rock Lake is an artificial lake or

reservoir A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including contro ...

The lake derives its name from a rock formation resembling a table at the small community of Table Rock, Missouri, on Highway 165 about a mile and a half downstream from where the dam was built.

2005 Dam Safety Project

Table Rock Dam’s spillway capacity was evaluated as a result of a dam safety program in the 1990s. Using improved weather data and more modern technology and safety requirements, engineers determined that the lake would rise ten feet higher during the worst-case flood than previously calculated. An event of this magnitude would overtop the earthen embankment and destroy Table Rock Dam with catastrophic losses in downstream areas, including Branson. After considering several options and gathering considerable public input, an auxiliary spillway was determined to be the best solution. The auxiliary spillway was completed in 2005 at a cost of approximately $65,000,000. Summary of projections: * At elevation 931 Table Rock Lake is at full flood capacity or flood pool. Water may begin to splash over the top of the closed Tainter gates and some of them usually begin to be slightly opened to accommodate additional lake inflow from the White River Basin including the James River and Beaver Lake discharge. If the Tainter Gates are not opened to release water via the dam spillway, water from the lake will begin to spill over those closed gates by approximately 933 feet. * At elevation 937 Table Rock Lake is 6 feet above flood capacity. All ten Tainter gates are opened wider in an effort to stabilize reservoir rise. Outflow from the Lake under these circumstances will be nearing 200-300 thousand cubic feet per second (CFS). * At elevation 942 Table Rock Lake is 11 feet above flood capacity and at its "design pool", or the maximum elevation that the reservoir is engineered to reach, under "probable maximum flood" scenarios. The dam’s ten Tainter gates will be fully raised to their maximum height of approximately 30 feet, releasing 550 thousand CFS into Lake Taneycomo. This scenario would effectively submerge and destroy the powerhouse, power transmission grid, hatchery, and wreak serious destruction downstream. * At elevation 947 Table Rock Dam would be at its maximum capacity and water would be at the very top of the dam. The auxiliary spillway would be brought online, in concert with Table Rock’s fully opened floodgates. This catastrophic or "last resort" protocol releases 1 million CFS of into Taneycomo and deals dreadful destruction to Branson, Hollister, Point Lookout and possibly the Powersite Dam. At this point there is a danger of water overtopping the concrete dam and breaching the earthen structure, which imminently leads to cataclysmic structural failure and the uncontrolled release of the Table Rock Lake impoundment—nearly 3 million CFS of water.

Historic Levels

Table Rock Lake has a record crest of 935.47 feet, which occurred on April 27, 2011. In December 2015, the dam released 72,001 CFS at its peak. This is the highest amount ever released.Little Rock District Corps of Engineers

Facilities and State Park

Sixteen public campgrounds are located around Table Rock Lake. Campgrounds are managed by several different agencies and campsites range from full-hookup to non-electric tent sites For details about each of the US Army Corps of Engineers parks, check out Recreation.gov. The US Army Corps of Engineers Dewey Short Visitor Center is located 6 miles west of US Hwy 65 on Missouri State Hwy 165 at the south end of Table Rock Dam. The visitor center has exhibits about the White River Watershed, local habitats, Table Rock Dam, and the US Army Corps of Engineers as well as several interactive exhibits including maps, power generation and water safety. It also features an overlook which allows visitors to view Table Rock Lake, the dam, and Lake Taneycomo from one viewing deck. The center shows a 20 minute film entitled, "Taming of the Riviera Blanche". This film is an introduction to the Table Rock Lake/White River area and details the construction and purpose of Table Rock Dam. The visitor center features a public-use dock, picnic areas, fishing, a lakeshore trail. Table Rock State Park provides public access to the lake. Six miles from Branson and located just south of the dam and outlet, facilities include a boat launch and full service marina (including cafe, boat rental and scuba dive shop), campground (including full RV hookups and a yurt), fishing access, swimming access (no beach), picnic area, amphitheater, hiking and mountain bike trails, and dump station.
