York, Peel, Durham, Toronto and The Conservation Authorities Moraine Coalition (YPDT-CAMC) Across a broad swath of south-central Ontario a coalition of 13 agencies are working together to better understand and manage water resources. The Oak Ridges Moraine focused program stretches from the Credit and Nottawasaga Watersheds in the west to the Trent River in the east and reaches from the shores of Lake Ontario northwards to beyond Lake Simcoe and the Kawartha Lakes. The program provides a multi-agency, collaborative approach to collecting, analyzing and disseminating water resource knowledge as a basis for effective stewardship of water resources. Agencies and consultants look to the program to provide the regional geological and hydrogeological context for their ongoing technical studies and management initiatives.
