Lake Edgar was a natural fault scarp pond on the upper reaches of the Huon River in South West Tasmania.
Lake Edgar was actually two small lakes that were created when the Edgar fault caused the plains below Mount Anne, on the upper reaches of the Huon River, to move upwards by little more than 6 metres, causing the river to dam and divert northwards around Scotts Peak. The lake was eventually inundated when the Lake Pedder was flooded as part of a hydroelectric power scheme in 1972. Lake Edgar should not be confused with the Edgar pond which was created when the Edgar Dam intersected one of the smaller tributaries of Lake Edgar.
