Runoff po­ten­tial near nor­mal to be­low nor­mal in South­west

The Southwest Booster - - NEWS -

Apor­tion of the ex­treme south­ern por­tion of the South­west is be­ing fore­cast to be in the be­low nor­mal runoff po­ten­tial cat­e­gory by the Wa­ter Se­cu­rity Agency.

Ac­cord­ing to projection­s in the March spring runoff fore­cast, there is an over 400 kilo­me­tre long re­gion along the Canada - US bor­der which is which is be­ing fore­cast to re­ceive be­low nor­mal runoff to­tals this spring. The Wa­ter Se­cu­rity Agency fore­cast notes that runoff bound­aries are only ap­prox­i­mate, but their mon­i­tor­ing shows lower snow ac­cu­mu­la­tions dur­ing the win­ter across the ex­treme South­west.

A snow­fall map by Agri­cul­ture and Agri-Food Canada show­ing pre­cip­i­ta­tion to­tals from Nov. 1 to Feb. 27 are ex­tremely var­ied in the re­gion, with most of the re­gion re­ceiv­ing to­tals rang­ing from 60 to 85 per cent of nor­mal and 85 to 115 per cent of nor­mal. There was only a small area which was rates as hav­ing re­ceived 40 to 60 per cent of aver­age pre­cip­i­ta­tion.

The Wa­ter Se­cu­rity Agency high­lights that irri- gation reser­voirs in the Mis­souri River, Swift Cur­rent Creek and the Old Wives Lake Basins are gen­er­ally near nor­mal for this time of year fol­low­ing a rel­a­tively dry late sum­mer.

“Al­though there are ar­eas within the basin with lit­tle or no snow cover, on aver­age the snow­pack is con­sid­ered to be near nor­mal.”

The low snow­pack in parts of the South­west are in stark con­trast to the well above nor­mal runoffs fore­cast in the Prince Al­bert re­gion.

“Cen­tral Saskatchew­an, from Saskatoon and North Bat­tle­ford to Prince Al­bert and Melfort, is ex­pected to see an above nor­mal to well above nor­mal runoff in cer­tain ar­eas,” Min­is­ter re­spon­si­ble for Wa­ter Se­cu­rity Agency Ken Chevel­day­off said. “We con­tinue to mon­i­tor the sit­u­a­tion and the Wa­ter Se­cu­rity Agency will be do­ing tar­geted snow sur­veys to ver­ify the amount of snow in these re­gions.”

The Wa­ter Se­cu­rity Agency will con­tinue to pro­vide up­dates as the spring runoff pro­gresses. The com­plete fore­cast in­clud­ing pro­jected lake lev­els and stream flows is avail­able at wsask.ca.
