Where is the nowcast used?
Nowcasts are provided for Huntington Reservation (Bay Village), Edgewater Park (Cleveland), and the
Cuyahoga River at Jaite (Brecksville).
Is it safe to swim in the lake or canoe in the river?
To find out, local agencies monitor the water daily to determine levels of a bacterium,
E. coli, found in sewage and other animal wastes. But because results of
E. coli levels take 18-24 hours by conventional methods, we are using other quickly-obtained measurements to estimate when
E. coli levels will be high. This is called a “nowcast.”

How does the nowcast work?
A nowcast estimates current conditions similar to how a weather “forecast” looks to the future.

How does the nowcast perform?
We are continuously monitoring performance of the nowcast and working to improve the predictive abilities of the nowcast.

Welcome to the Ohio Nowcast
A system that uses near real-time information to "nowcast" water-quality conditions at two Lake Erie beaches and one recreational river.
GOOD: E. coli bacterial levels are
estimated to be within the water quality standard and acceptable for
swimming.
ADVISORY: E. coli bacterial levels are estimated to exceed the water quality standard and be unacceptable for swimming.
