CURRENT FLOWS - KANANASKIS

Warning: Kan flows are now running 24 hrs a day due to run-off season. The flows may increase substantially and without warning. New, unmarked hazards may appear. Hazards can include trees floating downstream, new rocks downstream of the wave and more. Please review the area for hazards and report any hazards you notice. Not all hazards will be posted here.

 

FLOW FORECAST - KANANASKIS


How to read the graphs: Left side numbers are in cubic meters per second (cms). Bottom numbers are the hour in the day.
Flows changes take 30 minutes to reach the Mountain. Updates every 5 minutes.  Forecasting errors are due to Transalta operational requirements.
Mid/late summer and fall flows are normally two hours per day due to Transalta refilling reservoirs.

NB: The left numbers on the graph sometimes start above zero. If the left numbers on the graph start at 30 cms and there is no column it means the forecast for that hour is 30 cms.
