NWS forecast for this spot
Numbers are provisional real-time data. We don't rate rivers as safe or unsafe. Check local conditions, posted signs and official advisories (NWS warnings, park and dam-release notices) before you launch.
Kayak types for this river
We don't have verified river-class or character data for this stretch, so this is based only on USGS flow. Typical flow is about 405 cfs (median of daily medians, USGS daily statistics 1940–2026). In spring the 90th-percentile flow reaches about 16.7× that, so boats made for calm water (recreational sit-inside, inflatable, foldable, tandem) aren't suited at typical high spring flows; sit-on-top, fishing and touring kayaks handle moving water better (REI kayak guide).
- Sit-on-top: Pelican Bandit 100NXT (max 300 lb)
- Fishing: Eddyline Sandpiper 130 (max 390 lb)
- Touring: Wilderness Systems Tsunami 140 with Rudder (max 325 lb)

Documented hazards near this gauge
When flow is high: above the 90th percentile for the date or near NWS flood stage, expect more floating debris and strainers (downed trees that let water through but trap people and boats). Steer well clear of them (PA Fish and Boat Commission). Today's check flags this.
No documented hazards found in official sources. Scout before you go.
