I grew up in Oakland, fishing everywhere in every lake, pond, stream,river, and there are a few places people refer to as "Ramapo Lake".....The one I associate is as off Skyline Drive...As you head up there is a parking lot on the left and you have to hike/walk/trek ubout 20 minutes up a mountain to get there...It was easier when I was a kid but I most likely would have a difficult time lugging 2 tackleboxes and some rods up there....When you get to the top you hit the dam area(which I remember being very deep and holding tons of bass and pickerel and perch....You have to walk to the other side(another 15-20 minute straight walk to the "ranger station" area....that side which was not heavily pressured held the big ones....Growing up I have caught many 5+ pounders there(largemouth and GIGANTIC Pickerel as well).....There are also Monster Crappies in there....my biggest was prob. over 18 inches long and tons of perch....I stopped going there after I graduated H.S. and moved out of that area which was almost 30 years ago so I can't tell you how it is now....I remember though there were TONS of Black Snakes all over the shoreline and that prob. kept me from going back there many times.........There are no boats allowed(unless that's been changed) but I did once launch an inflatable raft there and explored and saw so much that couldn't be seen from shore....It's prob. worth a try.....Spinnerbaits.Poppers, and Live bait was my baits of choice back then.......Also texas rigged purple Creme 6" rubber worm of Mister Twister also......Good luck and hope that helps......
