I agree with Bill Cody we have 12 ponds and lakes in your area with smalles and perch half of which are kid"s rec. camps they have approx. 60% shallow water and heavy vegetation . Any pond or lake less than 14 feet deep and good water exchange do not support smalles year after year. If poor alk. or tannin water they will not spawn. Just simple facts,that are also listed in D.E.C publications. Our perch population has dropped off 40% in the last 4 Years and the Book Worms are still trying to venture why. Same as the Brookies ,drought condition's my guess.
Good Luck
