Mill Creek MetroParks is currently experiencing water quality issues in Lakes Newport, Cohasset, and Glacier. The reasons behind these issues are very diverse and are the result of many factors and practices that have been ongoing for decades. The most notable of these issues involves the elevated levels of E. coli bacteria that were discovered within the Mill Creek watershed. A prominent source of the problem is the combined sewer overflows (CSOs) from the City of Youngstown’s sanitary sewer system. While easily identifiable and quantifiable to a degree, the CSOs are not the only contributor to poor water quality in the lakes. Other contributing factors throughout the Mill Creek watershed include (but are not limited to): effluent from the Boardman sewage treatment plant, suspended solids, agricultural runoff, residential fertilizer, pesticide & herbicide runoff, parking lot & street runoff and failing septic systems. All of these factors directly impact the quality of our lakes and recreational opportunities for MetroParks visitors.

Hopefully this situation will help to raise awareness about the various problems contributing to the watershed issues. Ideally this will lead to changes in these long-established negative practices that impact the water quality in Mill Creek. Improvement of the water quality in Mill Creek Park lakes is a monumental task that will require continual effort, widespread support and massive changes in various ongoing practices throughout the 47,000 acre watershed. Northeast Ohio is fortunate to have an abundant supply of fresh water, and it is our duty to ensure that water remains fresh and clean for generations to come.
