Mike still no ansewer on the carp.. I fish the lake 20-30 times a year for the last 15 years, when we started seeing the carp is about the same time the shad showed up its time to face the facts and face it the shad were not put in the lake they made it back in the same way the carp did!!!! The shad are there and there is nothing you can do, my suggestion is turn the lake into a trophy lake since you have all the main ingrediants already, there is big bass and lots of food already present put a 25" size limit on the bass and 1 fish daily limit.. Still alow the tournaments and take the money you make from this events and buy fish yearly to stock the lake.. Sounds like a gold mine to me!!!
