Water levels on the South Saskatchewan River at Saskatoon will increase for the next few weeks. (CBC)

The City of Saskatoon is reminding people to be careful by the river.

Saskatchewan's Water Security Agency is increasing outflows from the Gardiner Dam over the next few days, which means the South Saskatchewan will rise.

The agency is expecting water levels to remain fairly high into June.

The move to increase outflows is being described as a "proactive release" because of the above normal snowpack in the Rocky Mountains, a higher than normal lake level for this time of year and recent rainfall events in Alberta.

Releasing water now provides the reservoir with capacity to hold water in the event there are heavier than expected rains.
