South Branch Grasse River.

The South Branch Grasse River drains northwest out of the Cranberry Lake Wild Forest, threading through low country between Tupper Lake and the St. Lawrence plains — working water more than destination water, crossing under back roads and logging routes without much fanfare. It's a put-in option for paddlers willing to scout access and deal with beaver work, but it doesn't show up on the short list of named Adirondack river trips the way the Raquette or the St. Regis branches do. The fishing and species data are thin, which usually means brook trout in the headwater tributaries and whatever moves up from the mainstem Grasse downstream. Check DEC atlases for road crossings if you're scouting a solo trip.
