Ward 11 News: Notice of Controlled River High-Flow Event on May 10, 2016

  • Share

Ward 11 official website

A controlled river high-flow event is scheduled for Tuesday, May 10th, 2016 on the Elbow River. This controlled river high-flow event is to occur in preparation for the upcoming flood readiness time period in Calgary - May 15th to July 15th.

On a routine basis, The City conducts river surveys and inspections to review river bed conditions and flow rates. Early this year, surveys and inspections of the Elbow River were completed for the area along 22 Avenue to 25 Avenue S.W. Based on our preliminary findings, the Elbow River bed and flow depth along this area have changed.

To confirm the findings and to calibrate the flow capacity in the Mission area, The City will be conducting a controlled river high-flow event, on or around May 10, depending on rain conditions. The City will carefully increase the Elbow River flow rate over a period of time to the range of 80 to 100 m3/s by controlling the release of water from the Glenmore Reservoir. This flow rate will not generate overland flooding.

For your safety and that of others, all people and pets are asked to stay away from the river edge and banks, and closed pathways on the Elbow River and the Bow riverbanks downstream of Inglewood during this controlled event. River conditions will remain high throughout the day and into the evening on the Bow River. This will pose an elevated risk to river users. City staff and emergency personnel will be onsite monitoring, from 7 a.m. to 5 p.m., the river levels and looking at potential impacts to river adjacent properties and communities.
