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,

Guage for Ridley Brook:
From the takeout bridge, look at downstream at the tunnel under the railway. the right wall of the
right side has a flat ledge. If the water is just reaching this ledge on the front corner, the
level is just about minimum. From that minimum level, things just get better. (until it gets too
high) You want enough water to get down, but not too much
