WSA advises that South Sask. River flows will increase following weekend deluge

The recent surge in rainfall over the weekend has resulted in the Water Security Agency (WSA) announcing that flows on the South Saskatchewan River between the Alberta border and Lake Diefenbaker will be increasing from 100 cubic metres per second (m3/s) to around 830 m3/s, with peak flows to occur by Thursday, June 26.

While Lake Diefenbaker has enough storage to capture the increase in inflows, the WSA is increasing outflows to the South Saskatchewan River to manage the increase to lake levels, which is expected to rise over one metre over the next 10 days. 

Outflows on the South Saskatchewan River are expected to rise from 65 m3/s to 75 m3/s between Lake Diefenbaker and Saskatoon.

The WSA advises that inflows and lake levels are variable based on weather conditions and reminds the public to take precautions around lakes and rivers as flows and water levels can change rapidly and without warning.
