YOUNGSTOWN, Ohio - We should know more next week about what caused Mill Creek MetroParks to close three lakes to recreational activities this past summer.

The Mahoning County District Board of Health on Monday will present the analysis of data collected during a twelve week water quality study conducted from July through October.

The tests began shortly after 21 News first reported a large number of fish had died at Lake Newport in late June.

Recreational activities at Lake Newport, Lake Cohasset and Lake Glacier have been suspended since early July as a result of the discovery of high E. coli levels.

The weekly testing included not only Lake Newport, but the streams that flow into the lake in an attempt to pinpoint the source of the higher than acceptable bacteria.

Ryan Tekac, Director of Environmental Health for the Mahoning County District Board of Health told 21 News on Friday hinted that his presentation is likely to focus on area wide watershed issues, as opposed to a single cause.

Tekac believes that a solution to the bacteria problem lies in further education about the watershed surrounding the park.

He hopes to receive feedback about the analysis from the stakeholders invited to the meeting.

Representatives from Mill Creek MetroParks, Mahoning County Soil and Water Conservation District, the City of Youngstown Waste Water Treatment Plant, Eastgate Regional Council of Government, Youngstown City Health Department, Mahoning County Sanitary Engineers, and the Ohio EPA have been invited to Monday's forum.
