The Water Security Agency (WSA) increased the release of water from Alameda Reservoir from three cubic metres per second (m3/s) to 30 m3/s.
This release was done on Wednesday in response to the recent heavy rainfall event in eastern Saskatchewan and is not expected to cause any impacts to downstream users. The release rate was reduced from initial estimates early on in the rainfall event. As the runoff volumes from the rainfall materialize, they are less than initially forecasted.
Outflows from Alameda Reservoir are expected to be at this level for roughly the next two weeks while floodwaters temporarily stored in Alameda are released and the reservoir returns to the full supply level. Alameda Reservoir was designed with flood storage capacity above the full supply level. For this event, WSA did use some of that available storage capacity.
Any further increases in outflow will be coordinated with the officials from the United States as per the international operating agreement.
There is no flood event or situation requiring the management of Boundary and Rafferty Reservoirs. They have been largely unaffected by this recent rainfall event.
The Water Security Agency was created to lead implementation of the 25 Year Saskatchewan Water Security Plan. The plan will improve water management capacity and service to individuals, businesses and communities across Saskatchewan. The agency brings together all of the major responsibilities related to water quality and quantity.
