Ice Surge May 2013
This is definitely the time of year to be thinking a lot about water. The Saskatchewan Water Security Agency provides information on flooding, water testing and safety, conservation and more. Get the contact information for your nearest watershed and find out what communities are doing to protect our water sources and quality.
Recently The SWSA recorded and shared this surprising and rarely captured video of an ice surge. The following is quoted from the first part of the video:
"On May 1, 2013 a large surge in flow into the Codette Reservoir on the Saskatchewan River produced something rarely seen. A large mass of ice (rubble breaking front), driven by a sudden increase in flow ploughed its way for miles across the ice on the reservoir.
The surge in flow was caused by ice melting for long stretches upstream. As the ice melts the river flow increases and accelerates where it is free of ice cover.
This video was taken by the Saskatchewan Water Security Agency during an aerial inspection of the river. To provide perspective, the ice breaking at the edge is piling up roughly three metres in the air.
The Saskatchewan Water Security Agency and SaskPower worked together to mitigate the impacts of this sudden increase in flow and reduce flood peaks downstream from Tobin Lake. SaskPower lowered their reservoirs in anticipation of prairie runoff and the potential surge flows."
You can find out much more about water in Saskatchewan at http://www.wsask.ca including information about the free water testing program (Provincial Flood Testing Program). The Water Security Agency provides a site assessment and no-cost water quality testing (bacteria and nitrate) for individuals that use private wells or cisterns that have been flooded.
