  1. Ghost reservoir is a working hydro-electric facility that has specific water licencing requirements and TransAlta is legally required to manage the water in accordance with the licence.
  2. Reservoir levels are affected by a number of different circumstances, not simply power generation.
  3. Even in normal circumstances, reservoir levels fluctuate. Boaters need to be aware of submerged hazards and floating debris.
  4. Reservoir elevations are subject to rapid changes during high-flow events as well as drought-like conditions. The public is highly advised to remain clear of all waterways upstream and downstream of hydro facilities, as flows can change rapidly and without notice. TransAlta’s first priority is the safety of its employees, the public and communities where we live and work. Obey all signage and barricades.
  5. Visitors and campers to Alberta’s parks are advised to review Alberta Parks and Banff National Park for current safety advisories.
  6. For information on reservoir levels and flows in Alberta, please visit Alberta Environment – river basins.
  7. Ghost seasonal drawdown begins April 1st, 2018.
