Drawdown

It’s inevitable. Thirty feet of water pressing on the face of a dam will gradually cause damage. Ice adds to the strain. Even when a dam is constructed of concrete and steel using the best building techniques, some damage will eventually occur.

From time to time these repairs will require that the water in the reservoir behind the dam be partly or even totally emptied. That process is called a drawdown.
