oak tree, entirely across river, exact location is 2.0 miles downstream of dam, visable from the
Branch Rd., 0.2 miles upstream of Route 101.
Lower Otter Brook is traditionally one of the first spring rivers run in NH. It is mostly a class
II run appropriate for novice and intermediate paddlers.
There is a nice hole/wave play spot formed by the dam outflow at the put in. Use caution here since
the concrete walls on either side could trap a paddler should the hole be the more prominent
feature. It is also very shallow so watch out not to roll here.
The river starts out with class II, winding its way through an alder thicket. This section is very
narrow and occasionally contains strainers and overhanging alders. Recent beaver activity has added
to the hazard. As of March 2002 a rather large beaver dam has been built about 1/4 mile below the
Middletown road bridge. Currently this dam is breaching in the middle and creating a very nice drop
and surfing wave, but the dam is being washed away slowly with each release or high water
The lower section of the river is wider with the additional flow from the Miniwawa river. Just
above the intersection with the Miniwawa there is a nice two foot ledge (Otter Ledge) drop with a
steep channel on river right. At levels above 600 cfs this river should be rated class II/III.
