That happens to alot of people.. Your lake is still huge.. If moneys not an issue get a full lake analysis done by a biologist or reputable lake management firm.. Try will shock and survey every aspect of the lake and tell you how to move forward the most efficiently.. Maybe Greg Grimes or Bob lusk can give you some names to contact also the pondboss magazine might have some leads for you.. With a lake that big it's just hard to do on your own..

I believe in catch and release. I catch then release to the grease..
