The lake is impounded by Table Rock Dam (located {{coord|36.595374|-93.311137}}) constructed from 1954 to 1958 on the White River by the U.S. Army Corps of Engineers.[1] It is a popular attraction for the nearby town of Branson, Missouri. There are several commercial marinas along the lake, and Table Rock State Park is located on the east side, both north and south of Table Rock Dam. Downstream from the dam, the Missouri Department of Conservation operates a fish hatchery, which is used to stock trout in Lake Taneycomo. The cold water discharged from the dam creates a trout fishing environment in the lake. 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.[2] Lake temperatureThe lake area temperature varies according to season:[3]
Lake dataDam and Outlet Measurements[4]
Flood controlThe original purpose of the reservoir was for flood control on the White River. The dam had been authorized a month earlier under the Flood Control Act of September 3, 1943. The reservoir has a fluctuation of {{convert|16|ft|m}}. When the reservoir is above the maximum flood pool, excess water goes over the auxiliary overflow spillway at the north end of the dam. The worst-case scenario of a catastrophic floodwater discharge from Table Rock Lake using the auxiliary floodgates would roughly resemble this: At elevation 931 Table Rock Lake is at full flood capacity. The ten Tainter gates are opened to accommodate additional lake inflow from the White River Basin including the James River and Beaver Lake discharge. At elevation 937 Table Rock Lake is 6 feet above flood capacity. The 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 letting loose 550 thousand CFS into Lake Taneycomo. This scenario would effectively submerge and destroy the powerhouse, power transmission grid, hatchery, and wreak serious destruction down stream. An illustration of how Table Rock’s ten spillways might appear under these circumstances mimics this: the floodgates will extend up and out from the structure, like eyebrows, shadowing the concrete spillways! 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 lake waters 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. Table Rock Lake has a record crest of 935.47 feet, which occurred on April 27, 2011. In December 2015, the dam released 72,000 CFS at its peak. This is the highest amount ever released.[5] Facilities and State ParkTable 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.[6]Area71 is a recreational vehicle (RV) resort, restaurant, and general store on Table Rock Lake in Shell Knob, Missouri. The store and restaurant were completely rebuilt in 2016 with an expanded menu and bait shop. The RV park features views of Table Rock Lake with long term site rental agreements. 2018 Boating Accident{{Main|Table Rock Lake duck boat accident}}Seventeen people were killed on July 19, 2018 when a duck boat filled with tourists capsized and sank in high winds on Table Rock Lake.[7] References1. ^{{cite web |url=http://www.swl.usace.army.mil/Missions/Recreation/Lakes/TableRockLake/DamandLakeInformation.aspx |title=Little Rock District > Missions > Recreation > Lakes > Table Rock Lake > Dam and Lake Information|publisher=U.S. Army Corps of Engineers |access-date=July 20, 2018}} 2. ^https://www.houseboating.org/The-Unparalleled-Appeal-of-Table-Rock-Lake-Missouri-Blog 3. ^{{cite web|url=http://www.bransoninfo.org/#!table-rock/c1uam|title=Branson|website=Branson|accessdate=July 20, 2018}} 4. ^1 2 3 4 5 6 7 {{cite web |url=http://www.swl.usace.army.mil/parks/tablerock/index.htm |title=Archived copy |accessdate=June 26, 2004 |deadurl=yes |archiveurl=http://webarchive.loc.gov/all/20040626075013/http%3A//www.swl.usace.army.mil/parks/tablerock/index.htm |archivedate=June 26, 2004 |df= }} Army Corps of Engineers 5. ^Little Rock District Corps of Engineers 6. ^{{cite web|url=http://mostateparks.com/park/table-rock-state-park |title=Table Rock State Park |work=Missouri State Parks |publisher=Missouri Department of Natural Resources |accessdate=December 27, 2016}} 7. ^{{cite web|url=https://www.cnn.com/2018/07/20/us/missouri-boat-incident/index.html|title=17 killed in Missouri duck boat sinking ranged in age from 1 to 70|last1=Hanna|first1=Jason|last2=Stapleton|first2=Anne-Claire|last3=Karimi|first3=Faith|last4=Baldacci|first4=Marlena|work=CNN|date=July 20, 2018|accessdate=July 20, 2018}} Further reading{{Commons category|Table Rock Lake}} 26 : Lakes of the U.S. Interior Highlands|Ozarks|Reservoirs in Arkansas|Reservoirs in Missouri|Protected areas of White County, Arkansas|Protected areas of Boone County, Arkansas|Protected areas of Carroll County, Arkansas|Protected areas of Stone County, Missouri|Protected areas of Taney County, Missouri|Protected areas of Barry County, Missouri|Buildings and structures in Stone County, Missouri|Buildings and structures in Taney County, Missouri|Buildings and structures in Barry County, Missouri|Buildings and structures in White County, Arkansas|Buildings and structures in Boone County, Arkansas|Buildings and structures in Carroll County, Arkansas|White River (Arkansas–Missouri)|Bodies of water of the Ozarks|Bodies of water of White County, Arkansas|Bodies of water of Boone County, Arkansas|Bodies of water of Carroll County, Arkansas|Bodies of water of Stone County, Missouri|Bodies of water of Taney County, Missouri|Bodies of water of Barry County, Missouri|1958 establishments in Missouri|1958 establishments in Arkansas |
