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. Our 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. In association with these local Municipalities and the Province, we are responsible for flood forecasting, monitoring, stewardship, education, plan review, and land management.
