Happy you mentioned the Ramapo Lake.
I went there for my first time ever this past saturday with 3 buddies of mine. The lake is crystal clear, you can see atleast 10 feet right to the bottom. Caught 3 pickerel & a friend caught a small bass. The place is great for day fishing. Just remember to bring pleanty of water and food, the walk back to the car was horrific.. You need to walk about a mile in to the trails to get to the lake.. Overall, i will definatly be back very soon!!!
