Just so you all know, Clark sold the land to Union County about 5 years or so ago for $1. Once that occurred the reservoir became public land. Google it. It's open access. Never once have I been stopped by a cop, park ranger/game wardens, or even a resident who has lakeside property. Union County police frequent the area between Milton Lake and the reservoir and have echoed the same exact sentiments I mentioned above--it's open. Just catch and release and carry-in, carry-out. The amount of garbage I see has disgustingly grown in recent years and that'll wind up ruining this great fishery for all of us. I also call the NJ wildlife when I see bucket brigades back there. And I have seen them come down and bust people fishing illegally or keeping things that were short or out of season.
