Thanks for all your comments and suggestions. Greg Grimes did the electroshock analysis and I have great respect for what he's recommending with the restocking of the lake. I think our developer is still unsure that starting over is the best to go and I wanted to get some reinforcements to Greg's recommendations.
We have some fish that have migrated up the creek and we can't get rid of those, so some of them will probably come back in the lake once it's refilled.
I also enjoyed reading your comments on fish habitat. Since the lake is still down (pending the water draining again from this storm today), we've put in some Christmas trees. I never would have thought of using pallet flats but have six of them sitting in my back yard right now. They'll work great in some of the areas right behind the house. Thanks again for your suggestions!!!
