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.

Cuyahoga Valley National Park is presently developing strategies to protect and enhance river values, including adequate and safe approaches for recreational river use.

While use of the river is not prohibited, there are several concerns that should be taken into consideration:

  • Canoeing and kayaking the river can be dangerous and the park does not maintain the river for paddling.
  • There are no developed access points or launch facilities for paddlers in CVNP.
  • Paddle at your own risk –you are responsible for your own safety. Always be aware of your surroundings, weather and water level. Know your equipment, limits and skills. Don't paddle alone, and let someone know your plans and when you expect to return.

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 radar-indicated rainfall as observed near the Akron-Fulton International Airport for the day prior to sampling will be used for the nowcast in 2015. 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”.
