Excellent news to see thriving walleye.
Even if they are cleaning up on some of the BC, it might take a while for any "dent" in the population to be readily observable by you.
Have you considered stocking a few walleye every year or every other year (ladder stocking)? That way you have some walleye eating every size class of your BC, except for the largest crappie.
P.S. Maybe post the length and relative weight of the walleye you catch this spring. Some of the actual management experts on Pond Boss might then be able to give you some very specific good advice.
