FORT McMURRAY, Alta. — With warmer temperatures on the horizon, officials in Wood Buffalo are urging residents to prepare for river breakup season and the potential for rapidly changing conditions along local waterways.
The Regional Municipality of Wood Buffalo says ice on the Athabasca and Clearwater rivers will begin to weaken, melt and break apart in the coming weeks, a process that can lead to ice jams and localized flooding.
Municipal officials say seasonal and permanent flood protection measures are already in place, including clay berms, water-filled barriers known as triple dams, pumps and underground infrastructure. Fewer temporary measures were required this year as work continues toward completing permanent flood mitigation in Fort McMurray by 2028.
All seasonal above-ground measures were completed by April 1, and Clearwater Drive has since reopened to two-way traffic. Some road and trail closures remain in place and residents are being asked to follow posted signage and stay clear of equipment.
Officials are also warning residents to stay off river ice and away from riverbanks as breakup approaches. Ice conditions can change quickly, with large sections shifting without warning and water levels rising rapidly.
The municipality says river conditions will continue to be monitored, with updates shared online and through social media. Residents can also access real-time information through a live river camera and provincial tools such as the Alberta Rivers app.
Officials are encouraging residents to review emergency plans, prepare household kits and consider options to protect properties, including participation in local sandbag programs.
The timing of river breakup varies each year depending on conditions such as ice thickness, temperature and water levels. Historically, breakup in the region has occurred between early April and early May.
