I have been reading about all the rain falling over most of California, but now I’m seeing the effects first hand. We re-visited our favorite winery in Sonoma this past weekend and found Lake Sonoma overflowing into various tributaries.
However, the flooding here is minuscule compared to the amount of water pouring over the Oroville dam in the foothills of the western slope of the Sierra Nevada mountains.
Thousands of (almost 200,000) homes downstream have been evacuated, but more hard rain is expected next weekend for this rain-soaked and flooded area. From extreme drought to extreme flood, weather fit for neither man nor beast.
UPDATE: water leaving the dam via the emergency spillway was producing too much erosion with the potential for collapse of that wall of the dam. Instead, engineers increased the flow out the concrete spillway today. Great video of the process on Vox: http://www.vox.com/science-and-health/2017/2/13/14598042/oroville-dam-flood-evacuation
