Never mind i think i found my answer...
Between elevations 937 and 942 the dam’s ten Tainter gates will be fully raised letting loose 450 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!
