Weather Report – April 2023

The BC River Forecast Centre’s most recent biweekly snow conditions commentary (March 22) finds the Okanagan’s snowpack to be slightly above normal (106%) compared to the long-term median.

The next official snow report, which takes into consideration the snow pillow data as well as the manual snow surveys as of April 1st, will be published on April 12th.

The April 1st bulletin is the primary bulletin for historic seasonal snowpack comparison.

After ramping up releases from Okanagan Lake, the Okanagan Dam operator with B.C. Ministry of Forests has decreased flows again. Although there is still a lot of snow in the hills, Okanagan Lake had been dropping more quickly than forecast, potentially threatening kokanee eggs/alevins. They will re- evaluate after April 1st.
