If you get to Walden Pond in Lincoln on the weekend early you can get in. Large trout, smallmouth and largemouth bass. Bring one rod and a pocket full of plastics. The place gets busy, weekday would be better, walk around the entire pond in the water. The only cover is along the shore, the bass will be right in front of you, cast along the cover. I'd use Tubes, Senko's Topwater should be perfect also. (It may be up to your eye balls with all the rain)
Buckmaster, in Westwood small pond has some big bass, trout also.
Jamacia Pond. most guys are fishing for the trout, plenty of big bass, big trout also.
