WSA releases preliminary spring runoff forecast for Saskatchewan
Global News
Runoff predictions are based on conditions at freeze-up, snowfall received to date, and the precipitation forecast up to the spring melt.
A preliminary report from the Saskatchewan Water Security Agency (WSA) states the spring melt rate is expected to have a significant impact on runoff yields in southern areas of the province.
How that impacts subsoil moisture levels or surface water supplies depends on the speed of the melt, the report states.
Most southern regions experienced very dry conditions last summer and into the fall freeze-up, and a below snowmelt runoff potential is being forecast by the WSA.
The prediction is based on conditions at freeze-up, snowfall received to date and the precipitation forecast up to the spring melt.
A slow melt in the south will likely result in the bulk of the snowpack recharging the soil, with a rapid melt likely needed to improve surface water supplies, the WSA said in its report.
However, the WSA said the current snowpack is not enough to satisfy both and that without additional snowfall, surface water supply issues will likely occur in the southwest region.
In the central region, an above-normal runoff is forecast with the snowpack above normal, however, flooding is not expected.
A near-normal runoff event is currently forecast for the north.
