Trolling has been slow for me all year. The single pole folks were doing pretty good until Friday. I trolled from daylight until about 3:00 for four days. Caught 16-9-6-16. Never found any concentration. Just picked up 1 here and there. Never caught 2 close together. Had two different people stop by while I was cleaning fish the last day and said they had been doing pretty good single pole fishing but they're fish were gone. One of them had caught 2, the other one hadn't caught a fish. I hope i'm wrong but the spawn may be about done at Enid. My wife caught one 15 1/4" that only weighed 1.6 lbs. Only caught one that was still bulging. Some of the eggs in the other ones are starting to get a gray color to them (white crappie).
