I was out for 5 hours yesterday (Thursday) and had no luck for walleye. I tried every wingdam, running back water and riprap that I could find. I tried the top of the wingdams, top, back side, close to shore and at the ends. I used crawlers, plastic and cranks. Basically everyhting short of using the last resort of a little dynamite. Nothing, nada, zero, zippo. 
Water was 58 – 59 degrees, with good flow and very little grass.
Maybe the water temps will fall and they will turn on.
Have a great day.
