Lake Ainslie is the largest natural freshwater lake in Nova Scotia and is the headwaters for the Southwest Margaree River. The lake spans over 20 km and has geological, cultural and recreational importance. The area was designated as a Canadian Heritage River in 1998. Lake Ainslie offers excellent Brook Trout fishing in the spring, boasts a significant population of White Perch throughout summer and is the primary breeding area for Gaspereau.  Boat launches can be accessed near Ainslie Village Campground and MacKinnons Campground.  The scenery is magnificent and anglers will surely encounter a bald eagle while on the water.
