About Us


The RLEF was formed by the Big Rideau Lake Association (BRLA) as a registered charity in 1991, to fund activities for the environmental protection of Rideau Lake and its watersheds. In 2001, its scope was formally broadened to encompass Upper Rideau Lake.

Since 1991, the RLEF has raised over $200,000 which has been devoted to such projects as water testing, bass tracking, loon and frog monitoring, and shoal markers. We have also assisted in challenging developments which could adversely impact the environmental quality of the Lakes. 

RLEF maintains an action fund intentionally held back to fund a project or opposition which requires more substantial financial resources.

A registered Canadian charity, we support projects that safeguard and enhance our lake environment.
Your donations are tax deductible.

Please give generously to support our work.
