Union

Lovely little Class II in-town run, with a walkable shuttle. A couple nice surf spots at most levels.
Put-in at the SE corner of the Rt. 1A Bridge, and paddle upstream a couple hundred yards for the first small rapid to warm up a bit. (At levels above ~4000cfs this is almost completely non-existent.)

As the river goes under the bridge, it enters a longer rapid, with a few wave trains, good eddies on both sides, and at some levels, a hole worth keeping an eye on right in the center, near the top of the rapid.

At the end of the rapid you'll find a surfing wave just to the right of a low rock with two bushes on it.

Next the river divides around an island with a half-dozen trees on it and rejoins for a short section of Class II.

A couple other minor features after that. Take out along the Shore Rd, or a little further down at Pump House Point, where there is a hand-carry ramp and parking for 3 cars. (Watch for poison ivy along the shore rd. In summer the Pump House is a safer bet.)
