If the amount of water entering a closed lake is increased beyond a certain level - for most closed lakes far more than would normally enter the lake - it is possible that the water level in the lake would rise so much that the lake would no longer be capable of absorbing it. This is rare but known conclusively in the case of Lake Corangamite in southern Victoria, when a succession of wet years during the 1950s caused the level of the lake to rise so much that it almost overflowed. There is a great deal of evidence that Lake Corangamite was an open lake prior to the end of the Little Ice Age - some evidence says it was an open lake for much of the Holocene due to a wetter climate.
