Night time with some flow going on down in the trophy area has rewarded me with some spectacular evenings. Throwing sticks at em seems to target the bigger fish for me anyways. Also you'll be surprised what comes through the gates. We've caught Gar, Drum, Smallmouth, and largemouth, whites, and of course the walleyes. One thing that works for me is wade out as far as you can, and try to get your stick in the flow. Then go with a super slow retrieve, rod tip up and let it just work the flow towards the surface. There were times when I saw or heard fish hit from below and come out of the water and set the hook on the splash.
Daytime in a boat, trick is usually just have to find em. We've beat the banks before too almost fishing them like bass with some good results. White jigs with a red neck is always my go to after gates are opened up. The shad coming through flips the switch I guess. Man I really want to go down now LOL...
