Well I wouldn't know anything about O.C.!!!
I grew up fishing both Walton and Round, I remember when they rented boats on Walton, almost across the road from the Country Convienience Store. Both lakes are Ok, Round being a bit better, Walton was better back when it had quite a bit more weeds. You should be fishing Round now for the big crappies, to the left of the island my young friend. Orange And Rockland lake was good at one time for numbers, but not size, until the guy with the ski boat took over the east bound Rt. 17 section.
Harriman SP is one of my old favorites, Benj is right on with Island Pond a favorite of all my favorites, a tough launch but the gem of all the lakes in the park, Power Worms in Camo and white double willow spinnerbaits around the pads, caught me my 7lber there, along with many 3, 4, 5 and 6lbers!!! My next choice would be Welch, for the smallmouths and a few decent largemouths as long as Hugefish has not molested them all
. In the early spring and late summer into the late fall Stahahe can be a fun lake decent size largemouths when you can hook up with them and when you can't seem to catch them the pickerel fishing can make up for the lack of bass.
Other places you may want to try is Winding Hills, Washington Lake, Glenmere Lake(not to far from you in Florida) and the unforgiving Bashakill Marsh.
You are about the same age as my nephew who goes to Monroe- Woodbury HS and lives right in your area of Monroe.
