The American River is adding another 60,000cfs where it joins IN Sacramento. Likely to also be increased.

Everything does ultimately end up in the Sacramento (I’ve been stuck in Chico for a week - while in college - when the levee at Hamilton City broke, and that storm was nothing compared to what’s going on now).
One break in one dam or levee and this will get ugly fast.
Your additional links, posted while I was typing, gave me more info. Thanks!
Besides Sac and below it in possible danger.
I’m concerned about our cities/suburbs along the delta.
We have younger relatives in the east bay supposedly protected by old levis and another family in lower Marin.
This week has finally woke them up re having a get out of low land and head for higher land plan before Brown’s water floods their homes and roads to safety.
We have room for both families. It would be tight, but our home is 290’ above sea level. If we get flooded, there will be no Northern California/Bay area.
We have told them that they have to bring their drinking water and food for a few days. Food that can be eaten without cooking and no water added.
Also, not to wait until everyone in their area is leaving like what happened below Lake Oroville this week.
Last but not least keep at least a 3/4 tank of gas in the vehicle with the highest road clearance to go through some standing water.
