It's been a couple years since I went over there, but I fished the big lake a couple times. Caught lots of little walleyes with only a couple keepers. The fishing was pretty good. I never tried the little lake. Also, I only ever saw one or two other boats out there.
If you're looking for a place to transition from pond fishing to lake fishing, I think JEC would be a good choice. I had good experiences there. This time of year you should call the guard house though. I think one of the lakes is open to waterfowl hunting now, but maybe one is still open to fishing.
I can't say for sure. Better call.
I am just pullin' your leg.:D
