Central Lake Ontario Conservation (CLOCA) is a local, community based, environmental organization and one of 36 Conservation Authorities responsible for managing watershed resources across Ontario. Established in 1958, CLOCA's jurisdiction is based on the watershed boundaries of 4 major watercourses and 18 minor watercourses draining an area of over 639 square km. Our watershed stretches from the municipal boundaries of Ajax/Pickering to Clarington, and north, from Lake Ontario to the crest of the Oak Ridges Moraine (see map).
We provide a wide variety of science-based watershed management programs and services, delivered in partnership with our municipal partners, local landowners, environmental agencies and all levels of government. Our municipal partners include the Region of Durham, Cities of Oshawa and Pickering, Towns of Ajax and Whitby, Municipality of Clarington and Townships of Scugog and Uxbridge.
