All of that is true. At the same time, it was a massive rainfall. There is no snowpack in the Lake Sonoma watershed. What was expected to be a 12 year fill occurred in 10 days, all from rain, no snow melt.dave54 wrote:The New Years flood of 97 was a rain on snow event. We had a series of relatively cold storms in November and December, leaving an above average snow pack down to low elevations. Then a warm tropical storm hit around 12/31 sending not only the warm rain, but all the melted snow, downhill. Locally it was determined after the fact, when all the data became available, to be a 70 year event. IIRC, the snow pack never really recovered after that.
