River Information

Welcome to the River Information Page
The Ohio and Muskingum Rivers are part of our history, essential to our community and an asset that we celebrate with the Ohio River Sternwheel Festival and others throughout the year. From time to time, floods or “high water” remind us that Mother Nature is always to be acknowledged, respected and accommodated.
Recent developments in technology and the arrival of the Internet now give us river level information in real time. Together with sophisticated forecasting and warning systems introduced in July, 2015, we are better positioned to prepare for high water events.
For real time information and other services visit the following links (which open in a new window). Click here for our local weather forecast.
