Last week we posted that Shuswap Lake levels were stable and that the 2020 snow melt runoff hadn’t started. Well, conditions have changed in the past week and Shuswap Lake level has definitely started to increase.
As we have done in past years, we will be tracking the Provincial runoff and river level forecasts for the Shuswap Lake and the South Thompson River. Based on their hydrological models, the Province provides a daily forecast 10 days into the future for the river discharge in all potentially flood prone rivers in BC, including the South Thompson River at Chase. Using their published data we can calculate the expected change in Shuswap Lake levels over that period.
Based on Tuesday’s projection for the next 10 days, we estimate that the lake level could rise an additional 0.60m (~2.0 ft.) by April 30th.
We will be monitoring this information as it is released by the Province and will provide you with a weekly update or more frequently if there is a substantive change in the projections.
