Good morning everyone,
Good news again this week with lake at 100% full and flow from lake at 32 cms (fisheries guidance flow is 15 cms).
What a difference a year makes – the lake has 2x as much water in it today as compared to lake level last year on this day.
The flow from the lake is 2x higher than the needed flow due to how much water we have and this condition will continue given the predicted wet warm weather melting the remaining snow pack.
Note that in 2019 the snow pack was fully melted by end of May and in 2020 we may still have snow pack melting in June.
