Hey Glenn, in regard to the perch/bluegill thing...at Piney Run we have noticed huge spawns the past few years and thousands of 4 to 7 in yellow perch are observed in the shallows from late April to late May. This year, alot of 12 to 14 in perch are caught around the docks this past 2 weeks on minnows and worms fished on the bottom. Just recently, however, and I believe in conjunction with the record high temps of a week ago, anglers were getting some bruiser gills in the mix, likely fish that are in pre-spawn mode as the water has actuallly dropped from 72 to 62 F this past week. We look for perch to fade out and gills begin to dominate during this overlap period of high aquatic activity that is seeing everything in the lake move shallow and feed aggressively. Hope it lasts a few more weeks!
Sorry forgot to tell you that most of the area is surranded by Allamuchy state park. That is the best way to find it on a map. Find the park and look to the East of it and find Rt 206. If you need more help let me know. I'm in that area all the time. Some good ice fishing there also, if you are into that.
If you look at a map of New Jersey. Look for a State Park called Allamuchy ( Al A Mooch E ) Water Loo Village is on Waterloo Rd. Jefferson Lake is just off of Waterloo Road, about mile mile and a half from Rt. 206 in Byram.
The lake is public, even has a boat ramp (Saw a 27 foot boat lauch out of it) The land around the lake is a private kids camp and they will call the police if you touch their land.
People fish by boat and wade. As long as you don't touch their land they have no say in your fishing.
Had the NJ State police come down one time (just checking the parking lot) and read the riote act to the guys from the camp giving some kids a hard time for fishing from shore.
Even tried to give my son and I a hard time. But they gave up and went away after I started taking their pictures!
