It does look like some carp survived the winterkill. I really don't think we will ever be able to completely eliminate carp in Lizard Lake or any other Iowa lake. The species is just too prolific and well suited to our freshwater lakes here in North America. Another fish that we are going to have a problem with in the near future is the asian carp or silver carp. snr.unl.edu/invasives/images/silver%20capr%20map.jpg The only way to control carp in my opinion is through a subsidized seining program for all Iowa lakes. This is what is done at North Twin Lake. Its also done in Minnesota and Wisconsin. In my opinion, the IDNR is not doing enough to promote or encourage commercial fishing for rough fish in the state. Make it profitable to catch carp and relax fees and taxes for commercial fishermen. You will see carp populations decline dramatically.

Sean, yes the carp and Buffalo fish will reproduce in Lizard Lake and every other lake that they get in to. Its a fact of life. A good fight was put up by all people concerned for the survival of Lizard. Now it is up to the DNR to keep its word that the lake will be restocked after the (Shallow Lake Management) gets started. I personally believe that this is the main fear of the( Friends of Lizard Lake). Restocking with Northern pike ,cat fish and perch will help keep the carp populations down.
Really carp reproduce who knew. I did. You know with such a big winter kill lizard lake is much cleaner. I seen it with my own eyes. If we had a fish barrier put in we could of injected the lake over the winter and saved money picked up all the dead fish and by the fourth of July had a beautiful lake. But since no one listened to the people lizard lake is doomed to shallow lake management. Through the living lake program. Are there any more meetings coming up or can we be informed of what is going on this year. Thanks, Andrew
It's not just the fear of the DNR not restocking Lizard Lake after the program is fully running, it's the fear that by dropping the water level a foot lower than it is that the lake will be able to maintain the restocked fish. If that many fish died from one winter kill at the lakes current water level, how many can we expect to die when the restocked fish reach average size?

The shore line of lizard is much bigger than it was say 40 years ago. Last fall I found a survey marker in the lake . The water was at a lower level last fall . I was walking the shore line when I spotted a cement post out in the water. It had a survey marker on the top . I don't remember the exact words on it but it was way before the DNR was around. What I am getting at is there was some pretty good fishing back then. People came from miles around to fish there.
I believe that a lot of the fish kill was due to the deep snow last winter. With the snow that deep the sun can't get through the ice to the algae to produce enough oxygen for that many big fish.
