Northern New York Waterfalls 

Flat Rock Falls


The north end of the Tooley Pond Road is less than 1000' from the junction of CR 17 and CR 27 in the hamlet of Degrasse.  Proceed northeast on CR 27 and take a right. Five miles down this road, the Twin Falls Hunting Club will be on the right.  Flat Rock Falls is on that property.

Degrasse Quadrangle

Flat 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, which has significant lengths that are unpaved, connects CR 27 in the hamlet of Degrasse to NY 3 near Cranberry Lake.  It is also possible to reach this location from the Route 3 end but our information details access from the north.

Please note that this particular waterfall is accessible either by boat on the river or through a private hunting camp.  It is actually one of the few areas in this region that is private and not state-owned.  My thanks are extended to Wayne Little, a former co-worker who was caretaker of the club grounds for 12 years.  He allowed us access to the falls and we took several pictures on May 15, 2010.

It is a bit confusing as to why this hunting club is named Twin Falls Club.  It is not in the area of Twin Falls, also on this stretch of river.  It is about two miles upstream.  To the best of our knowledge, Flat Rock Falls is the only waterfall in this immediate area.  Earlier topographical maps indicate it as "Camp Flat Rock".

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.
