So far I’ve seen no spike in the Oroville Dam inflow.

Is spring melt in Oroville usually way behind the rivers in central California? Are they still expecting a huge inflow spike at Oroville?

My understanding is that they get a good steady inflow from melt up til the end of June and possibly July in a year like this.

The biggest risk is from an unseasonal warm rainstorm. Sunshine warmth has a beneficial evaporative effect to the high elevation snowpack. Somewhere upthread there was information on the percentage of moisture evaporated in sublimation (solid to a gas).

The risk to the spillway right now is if the worst combination developed - a warm pineapple express. That would generate the greatest inflow spike.

AS for the norm, perhaps others have the typical history data (although this may not be exactly comparable to the existing snowpack).
