The discharge affect's the crappie in the area alot now this is just my oppoin, least week my friend's ended up with 25/few bass you will almost allway's catch a few them!!
I lived on the lake and fished it many year.
In the winter we uased to follow the steam from the warm water discharge.as the wind blew it around from cove to cove. that was key reason being the other side of the lake froze up but were the warm water did not the fish were! The dam side was the key most of the time as if you can find the weed line in these area's they can be productive! Did you try the ILL. board as i dont want to give up no honey hole's as my friend's will be staying at my residence,and fishing some lakes in my area,good luck!RFY
