River Description

Access through Dartmouth College land to the river is somewhat restricted. It is necessary to carry upstream from the take out unless special permission can be obtained. Carry up past the Dead Diamond tributary bridge and put in on the Swift Diamond as far up as you wish to hike. The Swift Diamond is mostly class III until the confluence with the Dead Diamond branch. At this point the river tumbles steeply through a narrow gorge with continous class IV water. Above 1000 cfs the gorge can be continous class IV-V with no let up till close to the takeout.

On August 28th, 2011 Hurricane Irene struck New England. The resulting floods caused extensive
damage throughout the region, the worst in over 100 years. More than half the rivers in Vermont and
northern New Hampshire recorded their highest flow levels ever. Many roads, guardrails, power
lines, bridges, trees and other debris now litter several rivers throughout the region. River beds
have been scoured and changed course, many new strainers make navigation problematic at best and
downright dangerous at worse. Please realize that the river description you see here may not match
current situation after the floods. Use common sense and when in doubt scout especially on blind
drops. Also, if you run this river in the next year or so please comment on its navigability, even
if there are no problems this will be very helpful. Please report any new strainers or changes to
the rapids that will impact future boating. Thank you,

The dead diamond at lower flows appears easy, and for experienced boaters who naturally read the
lines and go the right way, it boats easy too. But there are sieves and pinning rocks that have
almost killed people in the past. The gorge is no joke, and it should probably be listed as class
V, even if it seems really easy the 9 times out of 10 when nobody is in serious danger. It is best
to go with people that know it well, and especially those that know where the hidden dangers lie.
Above 2000 CFS its big water fun. Huge holes and wave trains. Edit
