Brazeau reservoir update: August 24

Due to the heavy rainfall in central Alberta, TransAlta will increase the water flowing through the Brazeau Reservoir up to 200 cubic metres per second (m3/s), starting at 5 p.m. on Wednesday, August 24.

There should be no significant increase in the North Saskatchewan River level due to our changed operations.

There is no need for us to begin using the spillway.

We have been holding back extra water in the reservoir/lake, which will be released over the next 4-5 days. We will use our plant and our generators to release the water.

While we have changed our operations to respond to this significant rainfall, we remain within the permitted operations of our water license and regulators are aware.

The rain event has affected only rivers and creeks, not lake elevations, with the exception of the Brazeau reservoir/lake, which has increased because we are holding more water there.

We will continue to monitor the situation of this weather event. At this time, there is no additional release required from the Bighorn plant and it will continue normal operations.



1. 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.

2. 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.
