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 2,740 cfs (median of daily medians, USGS daily statistics 1902–2026). In spring the 90th-percentile flow reaches about 5.5× 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).

Documented hazards near this gauge

Dams on this river within 5 miles of the gauge, from the U.S. Army Corps of Engineers National Inventory of Dams (updated 2026-10-23):

Tip: Portage around dams. Low-head dams can form a recirculating current at the base that is hard to see from upstream and hard to escape; rescuers should throw a line from shore rather than approach by boat (Ohio DNR; Indiana DNR).

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.

Wildlife

Verified presence within 25 km since 2000, from openly licensed (CC0 or CC BY) GBIF occurrence records (2026-10-26):

Water quality

We don't yet have harmful algal bloom (HAB) advisories for this spot. Check the Wisconsin HAB or beach advisory program before contact with the water, and keep pets out of discolored or scummy water (EPA harmful algal blooms).
