The water outflow from Lake Diefenbaker has been reduced in anticipation of reduced inflows from Alberta.
Patrick Boyle with the Saskatchewan Water Security Agency says the outflow from Lake Diefenbaker is now 80 cubic metres per second, compared to last week’s 120 cubic metres per second.
He says it will be .1 of a meter drop for the South Saskatchewan river downstream of the reservoir.
He says Lake Diefenbaker is about half a meter above the typical level for this time of year.
He says the agency wants to store additional water in the lake to avoid low levels this summer.
Downstream, he says irrigators may have to make a few changes.
He says some intakes may have to be adjusted along the river.
He says last year, the outflow was reduced to 60 cubic meters per second and it may occur again this year, depending on precipitation this year.
Boyle says much of southern Alberta is experiencing agricultural drought conditions, and expects irrigation diversions in Alberta to be above normal.
