Thank you Fishgurl, we would have to go back and really see if there was a fish kill in the lake for walleye in the 50's and 60's when the lake was full. I cannot remember that ever being reported but that does not mean that it did not happen. I guess my original point was that the walleye that were in the river survived very warm temps in the river for many years before we were here and the river has a history before the dam was here of being very low at times. Above Yamacraw it would almost be at pools at times not very deep and yet the fish could survive even in the summer or they would not be here to argue about.
