Beltzville lake is in Lehighton PA. It's a public lake, Blue Marsh lake is Armycorp in Leeport PA. $3.00 fee to use boat ramp at Blue Marsh, parking lot reenforced(when it full,it's full, you have to wait for "one out, one in" ) go fast as you can, very nice, very helpful and very professional water cops/rangers. No fee at Beltzville, overcrowded with jetski, parking is a messed, water cops sneaking up on you, stop you anytime they please doesn't matter if you are cruising within limit speed or anchored, and ask for all kind of document, speed is very strictly reenforced and zero professionalism.
