I was inspired by dschinski's report to put up a small lake perch post too though this is a bit late.
Killarney was treated with chemicals on June 10 for aquatic vegetation apparently. The post said eating fish was fine, although I limited the perch to eating once a week just cuz.
Managed two surprise holdover trout on ultralight gear so they were fun. Only about 12 inches but healthy looking. One of them swallowed a plastic worm that had blocked off its digestive tract so it was likely doomed eventually but was healthy when I caught it.
The perch were almost right below my feet, as I was in a float tube and the water was around 9 feet deep fishing just away from surface weedline in the main southern portion of the lake. Biggest perch was just over 10 inches so not huge. I put in a photo with a couple dink perch too next to the trout for people to reference what a dink is LOL. Actually, I caught a few that were so small I even released them (I usually keep every perch I catch because of overpopulation problems on these small lakes and encourage others to do likewise).
Caught a few bluegill too but the most effective method for perch was dropping a worm right underneath my feet, reeling in half a crank and waiting. Sometimes spinning in the float tube to put some motion to the worm worked well. When that didn't work, I'd throw on a bobber and cast/retrieve w/ worm about 4-5 feet under bobber. Probably caught 25 perch in total over about 4-5 hours so not relentless action but it was fairly consistent and did hit one school that kept me busy for probably 45 minutes.
