River Description

From Kenny Unser:
The Rattlesnake is west of Rt. 7 in Falls Village, CT. It is south of Canaan and north of Cornwall. Follow signs to Falls Village. When you see a small cluster of stores, continue under the railroad bridge and around the hydro plant. The Rattlesnake section ends at the Steel Bridge that crosses the river above the hydro plant. The run can be accessed on the river right shore just north of the steel bridge and just below Great Falls.

There is an annual Class-A slalom event on the Rattlesnake that draws boaters from around the country.

Updated water level information: The Falls Village power plant takes approximately 1500 cfs away
from the Rattlesnake section. If the river is running at 2000 cfs then the "Snake" will most likely
be running at 500 cfs unless the plant is shut down. It can be run as low as 200 cfs which opens up
the option of running the final drop of the great falls. (See video link below). At 500 cfs the run
is fun with lots of surfing, and above 1000 it starts getting juicy. At levels over 2000 the hole
at the big drop starts getting mean. You can call the local outfitters/ kayak shop in West Cornwall
for info on the level and the power plant status. Clarke Outdoors 860-672-6365
