Oak Ridges Moraine and conservation authority subwatershed boundaries
The watershed boundaries of the nine independent conservation authorities - CENTRAL LAKE ONTARIO, CREDIT VALLEY, GANARASKA, KAWARTHA, LAKE SIMCOE REGION, LOWER TRENT, NOTTAWASAGA VALLEY, OTONABEE, TORONTO AND REGION - collectively cover the entire moraine. Together, as of 2012, the conservation authorities own more than 14,000 hectares of public lands on the Moraine. This makes them responsible for the management of the largest and most strategically located tracts of land protecting the headwaters of the 65 river systems originating on the Moraine. These lands include both environmentally significant and publicly accessible recreational lands such as the Ganaraska Forest Centre, Fleetwood Creek Natural Area and Purple Woods, Thornton Bales and Albion Hills conservation areas.
