World Largest Hole in a Lake
This hole in the Ladybower Reservoir, Upper Derwent Valley, Derbyshire, England is reportedly World's largest bellmouth Spillway. Such spillways are provided in many man made lakes to automatically maintain the level of the lakes. These are designed like an inverted bell and are commonly called morning glory hole, plughole, glory hole, or bell-mouth spillways.
The Ladybower Reservoir has been provided with two bellmouth overflows (locally named the 'plugholes') each having inlet diameter of about 24.3 metres (80 ft) which tapers to about 4.5 metres (15 ft) at its exit located at the base of the dam.
