Bro if I'm correct (and I may not be), the Great Swamp is upstream from the small dam on River Rd. in Chatham. I'm sure a few pike have made their way up those falls, but I wouldn't waste your time up there. I have caught a pike a hundred yards downstream from those falls on River Rd. and every other pike I have gotten has been downstream from there. Hop on GoogleMaps and start looking for shoreline in between River Rd. in Chatham although way down to the confluence with the Pompton and even further to and past the Dundee Dam. I have done EXTREMELY well in parts of the river from Chatham to the Great Piece Meadows, but you're going to have to do the rest of the homework on your own.

Good luck.
