As far as seasonal temps, it goes from iced over all winter to about 72 in the middle of the summer. 72 was the peak last summer and it lasted about a week. This spring it climbed to 60 but has dropped back down to 52 as of yesterday because of the cold weather we have been having.

The too many mature bluegill and not enough spawning area was suggested to me on this site. After it was all said and done last year, I believe that theory was correct.

I'll work on getting some pictures of the koi and trout together this weekend.
