"We anticipate the river to collect debris from along the shorelines, creating hazards for boaters, river users and emergency responders, the river is unpredictable, and flow rates are likely to change rapidly and without notice – posing a danger to even the strongest swimmers”
Edmontonians are being asked to stay off the North Saskatchewan River over the next few days, as a scheduled dam release is set to raise water levels.
Starting Thursday, TransAlta said it will be releasing water from the Abraham Lake reservoir via the Bighorn Dam spillway that flows into the North Saskatchewan River west of Nordegg. The release of water from the Bighorn Dam is expected to increase the water flow rate and levels along the North Saskatchewan River.
River flows will increase over several days and reach approximately 175 m³/s.
Bighorn Dam is in Clearwater County, approximately 340 kilometres southwest of Edmonton.
TransAlta advises communities and outdoor enthusiasts downstream of Bighorn Dam that a release event from its spillway is to occur in 48 hours.
