Grass RiverDownerville State Forest / North Branch confluence access to Russell Route 24 bridge access
A planning-only 2.7-mile Grass River moving-water section from the Downerville State Forest / North Branch confluence access to the Russell Route 24 bridge access. American Whitewater describes a beginner-friendly Class I–II reach with one manageable rapid and a clear endpoint pair. NYSDEC documents public Downerville Forest parking, river frontage, designated campsites, and high-water/ford cautions; local access guidance identifies the Russell bridge, but the launch and landing remain access-area anchors requiring field verification.

CautionThis route has hazards or access considerations that require extra verification.
Safety details
Use fitted PFDs, cold-water protection, basic rescue gear, communication, and a written float plan even though the reach is mostly Class I–II. Scout the one stronger rapid and all bends for wood before committing.
- Use Chase Mills only as broad same-river trend context; no numeric threshold is asserted. Low water can expose rock and fast rain can raise the reach quickly, especially near the North Branch confluence. Turn around if the local visual does not match the group or boat.
- Downerville Forest access includes a public PFAR, river frontage, a ford that DEC warns can have dangerous high water, and seasonal road conditions. Do not drive through the ford, block the road/kiosk, or use private/leased shorelines for loading or bailout.
- Take out at the Russell Route 24 bridge access before any downstream continuation. Confirm a safe water exit away from traffic, anglers, and private banks; do not improvise a bridge, roadside, or residential landing.

Access map
Put-in
Downerville State Forest River PFAR Parking Area / North Branch confluence accessThe Downerville coordinate is the DEC River PFAR parking/kiosk anchor near the North Branch confluence, not a surveyed dock; the Russell coordinate is a Route 24 bridge/access-area anchor corroborated by route and regional access guidance, not a guaranteed boat landing.
Take-out
Russell Route 24 bridge Grass River accessNYSDEC warns that the North Branch ford is closed to motor vehicles during dangerous high water and that roads can be damaged or seasonal. Do not use the ford as a vehicle crossing or assume the access road is passable on the day of the trip.

Access notes and hazards
Access caveats
- The Downerville coordinate is the DEC River PFAR parking/kiosk anchor near the North Branch confluence, not a surveyed dock; the Russell coordinate is a Route 24 bridge/access-area anchor corroborated by route and regional access guidance, not a guaranteed boat landing.
- NYSDEC warns that the North Branch ford is closed to motor vehicles during dangerous high water and that roads can be damaged or seasonal. Do not use the ford as a vehicle crossing or assume the access road is passable on the day of the trip.
- The route ends at Russell Route 24. A visible downstream channel, roadside pull-off, or private shoreline does not establish a public landing, camping right, or emergency bailout.
Watch for
- USGS 04265432 unavailable, rapidly changing, or inconsistent with the Downerville/Russell visual; historical 0426475505 has no current discharge series
- North Branch confluence turbulence, one stronger Class II rapid, low-water rock, fast rain response, wood/strainers, cold water, anglers, and limited bailout options
- Downerville PFAR/kiosk, ford and road status, Russell Route 24 bridge traffic, safe landing, parking, private banks, and the mandatory downstream boundary
