The information on this page is updated by the Cuyahoga Valley National Park 4 days/week during the recreational season. This is a test of the nowcast for the Cuyahoga River. The nowcast issues advisories and predicts the concentrations of E. coli once a day at the posted time only. The predicted concentrations are for a specific site along the river and are for information only. Storms are likely to result in a quick change in water quality. Please be aware that there are no formal boat/canoe put-in locations at this river site.

Please use caution when contacting Cuyahoga River water. The river receives discharges of storm water, combined-sewer overflows, and incompletely disinfected wastewater from urban areas upstream of the park. These discharges result in a threat to the health of visitors who come into contact with river water during recreational use (e.g., wading or canoeing). Because park managers are concerned about the threat posed to human health by sewage and pathogen contamination, the park discourages any canoeing, swimming, or wading in the river.
