1. Actual operation may differ due to plant generation requirements or abnormal power system conditions.

2. The public is advised to remain clear of all waterways 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.

Also as a result of the flooding, recreational users at Ghost Lake and Bow River must be cautious as there are underwater hazards, water levels will fluctuate as we are actively managing reservoir levels and boaters are to expect heavy debris on the reservoir and the rivers.

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