Not likely to be anything running but dam release. Good plan to make it to Maine where there is a lot of dam release through the summer. Seboomic section of the West Branch of the Penobscot is a worthy, but distant, class 3 ledge pool drop, a fantastic run. The lower section of the Kennebec, putin below the gorge, runs every day and would work. The Dead River is right there next to the Kennebec and at low flows, 1,000ish, is 16 miles of deep woods class 2/3. Might be worth getting a little coastal paddling in. Acadia Nat. Park is *very* beautiful and there are multiple lakes, estuaries and coastal paddling trips that you could do. There are multiple tidal features up and down the coast as well.
