Yep, definitely white perch, 4-8". It's an 8 acre pond that I live on with 4 other houses around it. So draining is out of the question. The pond does not have any drainage above to bring in unwanteds. (3 feet low now due to no rain) No shad of any type that I have seen, only some small shore minnows. There is very little cover in the pond. I plan on sinking some brush that may give the bass a better chance at cracking down on the perch.
