TransAlta will begin lowering the reservoir elevation on April 5th, 2017 as per the agreement with the Government of Alberta.



1. In normal operation, reservoir and lake levels fluctuate during the day. The elevation indicated in this page is the lowest expected on the given date.

Reservoir and lake elevation is subject to rapid changes during high flow events. The public is advised to remain clear of all waterways immediately upstream and downstream of TransAlta’s hydro facilities as flows may change rapidly and without notice. TransAlta’s first priority is the safety and well-being of employees, the public, and the communities where we live and work. Obey all signage and barricades.

Visitors and campers to Alberta’s parks are advised to review Alberta Parks and Banff National Park for current safety advisories.
