Lake Taneycomo is a man-made lake on the White River in the Ozark Mountains of Taney County, Missouri. The completion of Table Rock Dam in 1958 changed the source of water to Taneycomo from that of the White River's flowing waters to the bottom tailwater of Table Rock Lake from the dam spillway and made it into a cold water lake. The clear cold waters from the deep tailwaters of Table Rock Lake pour out of the dam into Lake Taneycomo.
