Testing Of A Model For Predicting Recreational Water Quality Of The Cuyahoga River in the Cuyahoga Valley National Park Based On Real-time Turbidity And Streamflow Data
Water-quality concerns have long limited recreational use of the Cuyahoga River within the Cuyahoga Valley National Park. Park managers would like to promote the use of the river when conditions are appropriate, but the time required to obtain bacteria concentrations is too long to adequately assess the water quality and inform the public of a potential health risk—traditional bacteria-culture methods for determining concentrations take at least 18 hours from sample collection until results are available. A collaborative effort between the USGS and National Park Service has resulted in the development and testing of a nowcast system for the Cuyahoga River at one location within the Park. The nowcast is a mathematical system that uses easily measured environmental and water-quality “variables,” such as turbidity and rainfall, to rapidly estimate bacterial levels. Predicted bacterial levels are posted to the Ohio Nowcast website (http://ny.water.usgs.gov/maps/ohnowcast/) to provide the public with information to make informed recreational-use decisions about water quality and encourage the use of the river.

Development and implementation of a regression model for predicting recreational water quality in the Cuyahoga River, Cuyahoga Valley National Park, Ohio 2009-11
The Cuyahoga River within Cuyahoga Valley National Park (CVNP) is at times impaired for recreational use due to elevated concentrations of Escherichia coli (E. coli), a fecal-indicator bacterium. During the recreational seasons of mid-May through September during 2009–11, samples were collected 4 days per week and analyzed for E. coli concentrations at two sites within CVNP.
