Welcome to the Ganaraska Region Conservation Authority

The Ganaraska Region Conservation Authority's overall goal is the conservation, restoration, development and management of natural resources on a watershed basis while providing for the public enjoyment of the lands it oversees.

The Ganaraska Region Conservation Authority (GRCA) was formed in October 1946 under the Conservation Authorities Act and is one of the oldest conservation authorities in Ontario.

The watersheds of the GRCA covers an area of 361 square miles from Wilmot Creek in Clarington to east of Cobourg from the south shore of Rice Lake down to Lake Ontario. This area includes seven municipalities in whole or in part: Township of Cavan-Monaghan, Town of Cobourg, Township of Alnwick-Haldimand, Township of Hamilton, Municipality of Port Hope, City of Kawartha Lakes, Municipality of Clarington.

Notice to Ganaraska Forest Users

Please note that all trails are closed in blocks 114 & 137 for logging. Be cautious and safe when using the forest, and stay clear of all harvesting machinery.

A reminder that no open fires are permitted in the forest at any time and off-road vehicles must be equipped with spark arrestors. Should a fire be seen in the forest call 911 immediately and attempt to give an accurate location of the fire.
