The Ohio Nowcast is the result of multi-year partnerships on several projects between the U.S. Geological Survey (USGS) Ohio Water Science Center, and other federal, state, and local agencies and universities.

Monitoring and beach water-quality information are updated daily on the 2011 Ohio Nowcast by Cuyahoga County Board of Health (Huntington), Northeast Ohio Regional Sewer District (Edgewater), the University of Toledo, and the U.S. National Park Service (Cuyahoga River). Other partners on the 2010 Nowcast include Cleveland Metroparks, Ohio Department of Natural Resources (ODNR), and Ohio Department of Health (ODH). Current activities are supported by the U.S. EPA Great Lakes Restoration Initiative, the U.S. EPA BEACHES grant program (administered by Ohio Department of Health), and funding and in-kind services from partnering agencies.

Past funding for research and development supporting the Ohio Nowcast was provided by Ohio Water Development Authority, U.S. Environmental Protection Agency Advanced Monitoring Initiative, the Ohio Lake Erie Office, the USGS Cooperative Water Program, and the USGS Oceans Research Priority Plan.

Erie County Health Department, Lake County General Health District, and the City of Lorain are future partners on the Ohio Nowcast. These agencies are collecting data for development of predictive models at other beaches for possible inclusion in the Ohio Nowcast in 2012 or 2013.
