I'm not clear on the electrofishing data. of those numbers that you described, did they sample those fish or are they trying to make an educated guess on numbers of fish left in that 1 1/2 acre pool? It really makes no difference, it wont change my opinion of what you should do. I just queston how accurate those numbers are if that is a guess at numbers of fish left.

the solution to your problem is simple. drain the remaining porton of the lake. 1.5 acres is too large to try and treat with rotenone. I like to drain lakes down to puddles (if possible) before treating.

Even if you have to rent a few large pumps, get the water out. then your rotenone cost wont be outragous, and the labor to pick up dead fish will go down.

Since you are here in Georgia - Did you know you can get fish for new/renovated ponds for free? Call the Dept of Natral Resources in Social Circle for the application. you will get your bream this fall and bass next spring. and yup- it is absolutley free. you cant get more cost effective than that.

with the lake this far down you might as well take it all the way home. if you dont I would expect problems with those brown and yellow bullheads and crappie. they seem to be more resistant to rotenone. if they get out of control you will be looking at stocking adult bass to help correct the situation. Adult bass are expensive. Bullheads are known as nest raiders and if extrememly crowded you will have problems with them.

If you cant get the 1.5 acres drained out, I would not even try and rotenone. You will probably only kill the most desirable fish (bass and bream). just let it fill back up and assess the damage then. If you go this route, I would work very hard at getting the crappie, and bullheads out while the pond is 1.5 acres. Pull out all the stops, use traps and trot lines and hook and line. I hope your electrofishing contractor did not throw back these fish after the survey. shocking up the fish may work as well, not sure how cost effective that is (depends on who you are using to shock)

thats my take, hope it helps
