Lake Diefenbaker to See Moderate Increase from Alberta Rainfall

May 24, 2013 -- The Water Security Agency is advising the public that over the weekend inflows to Lake Diefenbaker will start to rise as a result of rainfall in Alberta combined with the alpine snowmelt.

The weather forecast today and through Saturday is predicting a large rainfall in southern Alberta of roughly 80-100 mm in places. This rainfall combined with the alpine snowmelt coming down the system will result in rising inflows to Lake Diefenbaker. Over the next 10 days, Lake Diefenbaker is expected to rise roughly 0.2 m.

Outflows from Lake Diefenbaker over the weekend will remain near current levels of approximately 300 cubic metres per second (m3/s) but will be re-evaluated Monday after the rainfall event.

At this time it is expected that flows below the reservoir will see a moderate increase next week but will remain well in channel.

This is somewhat of a common occurrence as the majority of inflow to Lake Diefenbaker comes in late May through June when the alpine snowmelt is running off and rain systems develop.

The Water Security Agency is maintaining close contact with the federal government and Alberta, Manitoba governments and will continue to monitor conditions going forward and adjust operations as needed.

The Water Security Agency was created to lead implementation of the 25 Year Saskatchewan Water Security Plan.  It will improve water management capacity and service to individuals, businesses and communities across Saskatchewan.  This new agency brings together, for the first time, all of the major responsibilities related to water quality and quantity.
