Gould Lake Conservation Area is a rural conservation area located in the Canadian Shield northwest of the community of Sydenham in the Township of South Frontenac, Frontenac County, in eastern Ontario, Canada.

Species of fish within Gould Lake include smallmouth and largemouth bass, pumpkinseed, and yellow perch.

Industrial expansion in the 19th century led to the opening of several mica mines in the Gould Lake area.

Picnicking, fishing, canoeing, wildlife viewing, cross country skiing, hiking, and swimming are the main activities visitors participate in.

The Limestone District School Board uses the original barn located near the beach as the focus of its outdoor education programs at the property.
