Thanks for the info. I would have never guessed bigger rocks would be better. Of course forgot my camera this weekend. Caught a few walleye and released them. Kept 3 perch one was 13 1/2" biggest yet. Noticed a bunch of 1-2" fish kind of look like walleye. Still too small to tell.Been very cold in western NY. We had snow 5/24. Actually put heat on 6/4. Sunfish opened their spawning beds up.
