Tooley Pond Quadrangle

Copper Rock FallsCopper Rock Falls is one of eight well-known waterfalls on the South Branch of the Grass River which are fairly easy to access from the Tooley Pond Road.  This road connects CR 27 in the hamlet of Degrasse to NY 3 near Cranberry Lake.  Like many of the falls on this road, it is on DEC maintained state land, accessible to the public.  It is also possible to reach this location from the Route 3 end but our information details access from the north.

This particular falls is 8.9 miles from the Degrasse end.  As you proceed from the Degrasse end toward Cranberry Lake, you will cross a bridge.  Don't be fooled. This is the Grass River and the access to Copper Rock Falls is on your left.  Of the falls on this road, it is the only one on that side of the road.

Copper Rock Falls is on NYS DEC land.  The hike is 0.15 mile on a trail that is not terribly well maintained but certainly passable.  As the trail reaches the river's edge, head upstream.  You are almost there.  

One look at these falls and it is obvious how it got its name.  The rocks in its path have large spots of copper coloring.  There are three channels here.  River right goes around the far side of an island.  If you look closely, you can see a plunge near the top of the island.  River left is the prominent channel and part of it diverts through the island near the top of its descent. 

If you visit early in the spring, parts of the trail might actually be under water and the river here is close to twice as wide as other times of the year.  When the Grass River is helping Mother Nature rid the Adirondacks of the winter snow, the river at this point is high enough that you won't even see the rocks that are present during the rest of the year.  During spring run-off, if it weren't for the trees, you may not even realize that these is an island there.

The Grass River flows into the St. Lawrence River in Massena, in St. Lawrence County.

Note:  Depending upon which map or sign you are using, this river is referred to as either Grasse or Grass.  Officially, it is Grass.
