Our Lake. Our Legacy.


The Big Rideau Lake Association is dedicated to building a strong community in a safe and healthy environment on and around Big Rideau Lake.

Located on the Big and Lower Rideau Lakes in Eastern Ontario, the BRLA is a non-profit organization with roots back to 1911. The Association is committed to long-term environmental protection and service to all who use our lake and share its resources. The BRLA supports programs in the areas of environment, recreation, government affairs and lake safety, and is managed by a volunteer Board of Directors, assisted by seasonal staff. 



BRLA Members are all those who enjoy the Rideau Lakes: cottagers, boaters and local residents. We each have a stake in protecting our lake community.




We count on your Support!

Membership fees alone do not cover the costs of the programs and services run by the Big Rideau Lake Association. We encourage you to consider making a financial donation to support the programs and activities you cherish as part of your lake community - either directly or, if you would like to receive a tax donation, through the Rideau Lakes Environment Foundation (RLEF).

Give the gift of the BRLA!


We are offering a unique gift program this holiday season, providing our members with the opportunity to share their love of the lake with their family and friends. We have three gift options: Shoal Marker Sponsorship, Cow Island Day Camp Participation or a Gift Membership.
