The City of Regina is working to protect areas from flooding, expected once spring runoff begins.

Sand bags and other protective barriers have been installed in several areas where officials expect water to overflow from Wascana Creek and Wascana Lake.

One area of particular concern is the western edge of the city and areas near to the creek, like the Cathy Lauritsen dog park.

Officials said Wednesday the topography around the park is a natural flood plain and it is very likely to be inundated.

Workers have also been out, in other parts of the city, surveying areas that could be vulnerable.

"We've done a lot of sort of detailed surveys around the city," the city's Jay O'Connor said. "[We've] had a look at elevations to make sure that we're aware of any buildings or infrastructure that could be impacted."

Crews have been laying sand bags for several weeks, in anticipation.

"Our system is built to deal with a great quantity of water," O'Connor noted. "What we're really paying attention to is the nighttime temperatures. When they really start to rise, that's when we're expecting to see the bulk of the melting occurring."

City officials said they are ready to close roads if the water gets too high.

O'Connor said in 2012, when there were no flooding issues, the water moving through the city crested — or reached its highest point — on Apr. 26.

He said they are expecting the water to crest, this year, on a date sometime after May 1.
