We are continuing to monitor the rate of snowmelt in the watershed and the resulting increase in lake levels. The automated real-time snow pillow data available from the Provincial River Forecast Centre clearly indicates that the high elevation snow pack has started to melt. Therefore we can expect an increase in stream flows as the melt progresses over the next week to ten days.
We are also monitoring the stream flow forecast for the South Thompson River at Chase prepared by the River Forecast Centre. Over the past week the rate of increase in discharge at this station has slowed, consistent with the slower than expected rise in the level of Shuswap Lake. With today’s forecast, the slower rate of rise is expected to continue through the long weekend and then increase again. Over the next ten days, based on the forecasted rise in river levels, the lake level should increase approximately 0.3 m (1 foot).
We continue to be optimistic that the lake will not reach flood levels in 2019. We will post another update at the end of next week.
