Source Water Protection

While the protection of our drinking water happens on multiple levels, Central Lake Ontario Conservation (CLOCA) is committed to collecting data on the quality and quantity of our water, at its source.    Source water is our untreated water from streams, lakes or underground in aquifers. 


Our upstream approach of preventing initial contamination of source water eases the burden on our water treatment and distribution systems downstream. 




CLOCA is part of a broader Source Water Protection Area that includes neighbouring Conservation Authorities Toronto and Region and Credit Valley, which is referred to as the  CTC

Recognizing the shared water resources, we are working together to monitor, identify threats, and regulate water protection across these three jurisdictions.

Healthy watersheds for today and tomorrow.

Our watershed is located on the traditional territory of the Williams Treaties First Nations, the Chippewas of Beausoleil, Georgina Island and Rama and the Mississaugas of Alderville, Curve lake, Hiawatha, Scugog Island.
