Operation will follow requirements from Alberta Environment and Parks as per the multi-year agreement with TransAlta. More info here.


  1. Random flows (~10 cms) are being released overnight from the Barrier reservoir due to frazile ice downstream.
  2. Actual flows and levels are often more or less than projected and at times can vary considerably. Actual flows are also subject to change without public notice.
  3. 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.
