For people in Saskatoon, the South Saskatchewan River can look like a welcome oasis of cool when steamy summer heat settles into the city.

The fire department, however, is warning that those cool, inviting waters can, are in fact, dangerous.

 In a news release, the fire department said that “recent rainfalls in Alberta and consequently high water levels have created strong river currents, a persistent shifting river bed and slippery river banks that may be unstable near the water’s edge.”

If that’s not enough to keep people out of the water, officials offered a reminder that Bylaw 4422 prohibits swimming in the South Saskatchewan River within city limits.

The fire department is also suggesting boaters be careful, and warned that people who do not have experience boating on the river think twice.
