Sturgeon Lake Watershed Characterization Report 2014 ii STURGEON LAKE WATERSHED CHARACTERIZATION REPORT KAWARTHA CONSERVATION About Kawartha Conservation A plentiful supply of clean water is a key component of our natural infrastructure. Our surface and groundwater resources supply our drinking water, maintain property values, sustain an agricultural industry and support tourism. Kawartha Conservation is the local environmental agency through which we can protect our water and other natural resources. Our mandate is to ensure the conservation, restoration and responsible management of water, land and natural habitats through programs and services that balance human, environmental and economic needs. We are a non-profit environmental organization, established in 1979 under the Ontario Conservation Authorities Act (1946). We are governed by the six municipalities that overlap the natural boundaries of our watershed and voted to form the Kawartha Region Conservation Authority. These municipalities include the City of Kawartha Lakes, Township of Scugog (Region of Durham), Township of Brock (Region of Durham), the Municipality of Clarington (Region of Durham), Township of Cavan Monaghan, and the Municipality of Trent Lakes. iv STURGEON LAKE WATERSHED CHARACTERIZATION REPORT KAWARTHA CONSERVATION Acknowledgements This Watershed Characterization Report was prepared by the Technical Services Department team of Kawartha Conservation with considerable support from other staff.
