Welcome to the Trethewey Beach Society.

Trethewey Beach is a charming lakefront community located in Windermere, just minutes south of Invermere on Lake Windermere in the Regional District of East Kootenay. This community is home to a number of permanent residents in addition to recreation property owners that have fallen in love with what is commonly regarded as the gem of the Columbia Valley.

Bordering the lake is a large section of private property and a private marina which is owned by residents of the subdivision itself. A Society is in place to ensure the maintenance and protection of the beach, marina and undeveloped lands according to its bylaws. An Annual General Meeting is held, typically on the long weekend in May and all owners are strongly encouraged to attend.

This website is intended to provide residents and visitors with community and Society updates, as well as acting as a source of information and links to many of the things a typical owner would like to have access to. 

Feel free to contact us at tbs@tretheweybeach.com with thoughts and suggestions.
