Flow Forecast: Ghost & Bearspaw Reservoirs

Please note that flow forecasts although low are relatively stable at this time of year. Flow forecasts will be discontinued on October 2017 until the spring of 2018.

The flow forecasts are a predicted daily average flow and are governed by upstream supply. During the course of the day flows can fluctuate to meet the daily predictions.


TransAlta the operator of the Ghost Reservoir on the Bow River upstream of Calgary entered into an agreement with Alberta Environment & Parks (AEP) in 2014 with a pilot project to assess a flood mitigation model that would aid in the control of the Bow River’s seasonal high flows.
