We have many good Freporters and good experts commenting on these threads.
Kudos to the ones pinged above and the many I missed.
Hopefully this last minute action taken will work on the spillways.
There is another bigger issue, and Mariner and I have tried to bring that into focus.
Water flows downstream and into the streams, rivers, creeks, reservoirs below Oroville to Sac and then the Sacramento River and its tribs into the Delta.
With the rains predicted this week and later over and into these watersheds, we could be facing a huge and terrible situation. We don’t have room for any large amounts of rain and run off down stream.
Mild rain is hitting some of the areas north of SF at this time. 10:38 am, 8/15. I don’t think that was predicted for these areas, this early.
Not sure if you caught the video in post #1014:
Look at the massive water flow of the Feather River, Sacramento River and Lake Oroville 3:02

Shasta weather calls for 5-6 inches of rain over the lake, and likely 8 inches in the mountains above. Snow level will determine ultimate risk.

They have been releasing 75,000cfs since Monday, the highest in a decade, to get the level down to 93%.

When combined with releases out of Berryessa and Oroville and all the other tributaries (Yuba River etc.) there’s easily 300,000cfs passing through Sacramento now, before the rain starts.
Two islands in the Delta have already been evacuated and are flooded.
Now we know the southern end of the Valley has a similar problem with the San Joaquin river at flood stage along with all of it’s upstream dam and tributaries. They are all at 90+% storage, again the rain has not started yet.
They all have to release large amounts of water to maintain the integrity of the dams.
The next 10 days will be at least interesting and exciting.
The media is nearly silent on this matter.
