Table Rock Lake is an artificial lake or reservoir in The Ozarks of southwestern Missouri and northwestern Arkansas. The lake is impounded by Table Rock Dam, constructed in 1954-1958 on the White River by the U.S. Army Corps of Engineers.[1]

It is one of the popular draws 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 Lake Taneycomo.

Lake air temperature[edit]

The lake area temperature varies according to season:

  • Spring: 56 to 77 °F (25 °C)
  • Summer: 85 to 90 °F (32 °C)
  • Fall: 71 to 82 °F (28 °C)

Flood control[edit]

The 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 16 feet (4.9 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.
