Ohio Nowcast.
Welcome to the Ohio Nowcast for the Cuyahoga River

Cuyahoga River

The Cuyahoga River at Jaite (Brecksville, Oh) is in the Cuyahoga Valley National Park.

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.

For futher information, contact Meg Plona, National Park Service (meg_plona@nps.gov).

See you next year...

Variables used in the Cuyahoga River nowcast models

For the Cuyahoga River at Jaite, a model based on turbidity as measured by the in situ turbidity sensor and rainfall as observed at Akron-Fulton International Airport for the day prior to sampling will be used for the nowcast in 2014. On days when the predicted E. coli concentrations in the river are below 298 colony-forming units per 100 milliliters, the water quality will be considered “good”. More, coming soon...
