The management policies seemed to work up to the point that they lowered the lake. The fishery has definately declined since then. I'm not sure that much can be done about it though. The water temp and oxygen level have more to with the problem then anything else and they will always put the safety of the dam before the needs of the fish.

Once the dam is finished and the lake raised back up to the regular level I do expect a fish explosion due to all the new cover and space. A couple years after they raise it back up the lake should be amazing. Until then not so much.
