fishing too deep ??
I'd be throwing a 1/32oz marabou under a float - to the open banks ...... and a 1/32-1/16oz weedless jighead/tube jig to the weeds and wood. And I'd be fishing the 1-6ft range of water depth, and looking for some wood/weeds in that depth....esp. if the water is clear enough that you can "see the beds". (are you sure you weren't seeing Bluegill or Bass beds?)
Considering your location ... the spawn should have been pretty much over, by now ... you sure they aren't post spawn and suspended out in open water (resting & recooperating from the spawn) ?? ....... cp
