River Description

The Blackwater is located in Webster NH just west of Concord. The river alternates between flat water and violent drops. From the put in to Clothespin bridge the river has a few class I and II drops with play waves. Once Clothespin bridge comes into view, then its time for the novices to take out. The river then becomes more difficult with each drop. See description below. There is a class V-VI rapid just below Blackwater dam just upstream from the normal put-in. This rapid is short but very steep requiring a lot of manuevering around pinning rocks and big holes.

Clothespin Bridge (Class IV, Mile 1.0)

When a bridge is visible on the horizon line get ready for a good ride. Clothespin is a 5' verticle drop into a frothy hole. Run right of middle and turn towards the left just as you go over the drop. Brace and be ready for a roll at the bottom. The river is very narrow at this point and can accelerate a boater into a rock wall.

A rapid (Class III+, Mile 2.0)
A fairly long rapid with lots of holes to manuever around. Nice playhole on river left at the bottom of the drop.

Eggbeater (Class IV, Mile 2.3)

One of the most difficult regularly run rapid in NH. Eddy out on river right just as the river takes a hard left and scout. This is a long steep slide that leads up to a ledge drop with a stickey hole at the bottom. The approach to the ledge is very turbulant with large stickey holes. At levels below 1000 cfs there are several micro eddy's to catch along the way. Above 1000 cfs these eddies turn into violent wirlpools and holes. After the ledge drop the river calms down a little until you reach the takeout 200 yards below the bridge.
