I havent tried gisberg ponds yet but I had a friend who swore he was catching bluegills out of there so I have to give it a try.My dad used to take me to green lake and we used to fish off the dock by the island at night,we used to get 10 or 15 sometimes(catfish),they were bullheads,but they were great eating.I havent been back for at least 14 years so alot could have changed,I know I would love to catch a muskee,I have never tried it...back to gisberg,I also heard there are alot of crawdads in there.
