I was pointed in the direction of this website by a friend. I am in the conservation field in the state of MN and have been involved in some shallow lake restorations. The purpose of joining this website is to try to show what can be accomplished by shallow lake management (getting rid of the carp).
My first example lake is very similar to Lizard Lake. It is roughly 600 acres and max. depth is 5.5 ft. It is connected to another lake via a 3-4 mile long stream channel. In 2009 an electric fish barrier was installed and in the fall of 2009 a cemical rotenone application was done. All carp were eliminated and the water quality improved instantly.
Pre-reclamation, very poor water clarity and water quality
Post-reclamation, immediate water clarity improvement
Fish were stocked the spring following the reclamation Nothern pike at stocking (May 2010)
Yes, you do get increased amounts of vegetation after a reclamation
Aerial view post-reclamation, as you can see some vegetative growth around the edges, the whole lake DID NOT sprout vegatation. Boaters are still able to use the lake and you still can fish from the shore lines.
Is this Pickerel Lake in Minnesota? From what I have read, the lake was not drained. Only a fish barrier installed and the rough fish eliminated with rotenone. This is what many of us want for Lizard Lake. The part of the plan for Lizard that worries me is lowering of the water level. I hope they bring the lake back to its current level after they are done.
