Water Supply and Conditions Outlook - Oct. 1, 2017
Despite very low rainfall and very dry soil, water supply conditions across Saskatchewan are mainly adequate with reservoir levels generally at or slightly below average levels for this time of year. Deeper groundwater supplies also remain at above average levels due to recent consecutive years of above average rainfall. At this time, there are some issues related to water supply shortages in smaller reservoirs and dugouts in southern Saskatchewan along with issues with deteriorating water quality.
Rainfall since April 1 has been extremely low over southern Saskatchewan, well above average over central Saskatchewan, and below average in northern Saskatchewan. In fact, cumulative rainfall since April 1 ranges from record low in a number of areas in southern Saskatchewan to record high in the Meadow Lake to Buffalo Narrows area.
Streamflows across southern Saskatchewan are generally near average for this time of year. Flows are typically near zero in the fall on most small prairie rivers and streams. On the Souris River, Qu’Appelle River and Saskatchewan Rivers flows are being supported by reservoir releases.
