Following an abnormally dry February, a pair of ‘atmospheric river’ events brought copious rain and snowfall to central and northern California between March 4-14. This resulted in reservoirs in northern California reaching or exceeding 100% normal capacity for the first time in years. Snow depths in the mountains also met or exceeded normal values for March. However, as the water year and the El Nino wind down, the overall season is ending up as just an average one, not the hoped for ‘much above’ average that was expected given the powerful El Nino that was present. Here are the details for the end of March.
