I was in the same area today at the same time, and I can confirm BB's report to a tee. Put in at Eagle Rock around 11:00 or so, and stayed out till about 4:00 or maybe 5:00 when we pulled out. Went north first, up to around Big M and that area up there, then back south, eventually all the way down to the Holliday Island area. We caught little bass on craw pattern cranks and a jerkbait, but nothing on plastics (I accidentally left my 'good' jigheads in the back seat of the truck though; typical). The water temp always measured 49.something, saw some variance, but never five-oh. The catches we did have seemed to be coming out of shaded areas into light on the wind blown shore side.
Talked to some guys at the ramp when we were leaving and they had come out for Crappie and Whites and had had a terrible day.
