Arms Park (aka Crack Pipe)

Jim Cavo wrote: Approx. 1/4 mile of class-II rapid. The river is bordered by a high seawall and access is limited. The putin and takeout are at Arms Park, at the large steps along the seawall. There are plans to install permanent putin steps upstream.

There are numerous permanently installed slalom gates, and many well defined eddies making this a good site for practicing slalom and attainment. Unfortunately, the play wave/hole described in Appalachian Whitewater was almost entirely washed away in high water several years ago.

Flow is controlled by Amoskeag Dam, but runs most afternoons and evenings. There'’s a good brew-pub adjacent to the park.

Directions: From Rt. 293 take Exit 6. Cross river on Granite Street. After crossing river, take first left onto Commercial Street and follow Arms Park signs; the park is about a mile ahead under a large bridge.

Paddlers' each can have their own opinion on the best level for the Crack Pipe Wave. The range of opinions go from 3000 cfs to 9000 cfs. Some prefer 3500–4500; others will say 6000–9000 is best. A few like it as low as 1500 cfs. What most agree on is if the level is not to your liking then head downstream to try the 293 Wave.
