thanks for the reply's. I have a healthy population of CNBG up to about 1.5 lbs. They are fed every day and I monitor their health monthly.
I've got the ok to add Tilapia to the lake and larger golden shiners. Tilapia last year did well.....until the storm of the century. But the tilapia that were in the lake before the freeze were up to about 2 pounds before they bit the dust. Also have a very good population of Red Ear which had a very good hatch this year. Those 5 YO RE were over 1 pound.

Another question........at what depth does a 16 pound bass spend it's summers? Max lake depth is 20 feet. I'm considering adding structure to the deepest section (away from the reach of land-based fisher-kids) to give the big lady (Gertrude) some loafing cover.
