The first place to try is the spillway. I've caught a lot of fish there. Gull point has some good fishing at times. Any bridge. The trestle. This fall they cleared off the trees south of the trestle so that opened a lot of shore fishing. If you find the right dock, you can catch tons of big bluegill. Good luck. I'm not an Okoboji summer expert. Nor winter, but I go pretty often some years
