River Description

STRAINER ALERT-

Posted 3/29/07
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 event.
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.
