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

Trail Closures
The Ganaraska Forest timber harvest season is in full swing. Keep your eyes out for active cut blocks and closed trails. Remember to stay clear of areas where harvesting is occurring - be cautious, be safe!

All trails leading up Lookout Hill are closed to motorized users until further notice. The location had already been closed for many years, and despite signage, the use continued, resulting in further erosion. New signage has been erected and the area will be enforced.

Please be aware that trail maintenance is scheduled in the West Forest for the month of September to address whoops, erosion and banked corners. Signage will be put into place, but the GRCA urges users to be cautious on all trails, especially on hills and corners. Heavy equipment will restrict access to some trails. Please yield to all machinery and be aware that the operator may not be able to see you.

If you have any questions or concerns, please do not hesitate to contact GRCA's Forest Recreation Technician, Ed Van Osch - 905.885.8173 ext 325

Stay on the Trails!
Poison Ivy is very prevalent on the Ganaraska Forest recreation trails. A good rule of thumb is: Leaves of Three? Let them be. If you think you have been exposed to the toxic oils, there are showers in the washroom facilities located across from the gymnasium at the Ganaraska Forest Centre.
