In our last post we estimated that the lake level would rise to its annual peak by the 29th or 30th of May – and we were right. Actually, the staff at the Provincial River Forecast Centre did all the legwork with their forecast models. In summary, Shuswap Lake levels in March were about 0.3 m below normal but the snowpack in the watershed were well above normal, enough for the River Forecast Centre to warn that runoff could reach an amount only experienced once in 100 years on average. As we said at the time, the weather was the wildcard and if it could have been a “normal” April and May with substantial rain, these extreme water levels could have been reached. As we all know now, May was one of the driest months on record. The result, even though it was high, rising 3.3 m (10.8 feet) to levels expected to occur about once every 10 years on average.
Enough with the statistics. Since the lake level peaked over a week ago, the level has steadily dropped and as of today it has decreased 0.4 m (1.3 feet) and should continue to drop through the summer and fall. We wish you a pleasant summer.
When boating on the lake continue to look out for debris. It will take a while for it to either move through the lake or get hung up on shore.
