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.

There is now a major danger that many of the islands southwest of Rio Vista may go underwater, and cities like Antioch, Pittsburg and Martinez could be threatened. And it could threaten the oil refineries just east of the Carquinez Strait and in northern San Pablo Bay, too.
There are some weather forecasters who fear we could have a repeat of at least 1997, or possibly even the horrible 1862 floods that essentially sank much of the Central Valley underwater.
This page has "conditions for major reservoirs," including Oroville and Shasta. It has bar graphs showing total capacity and percentage of historical average for the date. Perris Dam is being reinforced, and water levels have been kept lower than they'd be otherwise; every other reservoir here is near or above the historical average now.

This page is for Shasta. It has that same bar graph and a line graph showing change over the year, with different years available for comparison.
I’ve no idea.
I vaguely remember Wham.
Even without rain, in the 90 mile radius from SF, there are new and old mudslides happening and closing roads or limiting traffic to one lane.
It is warm in this area, about 50+ degrees @ 7 am, and 1-2 inches of rain is predicted for tonight and tomorrow.
Route 50 to the Tahoe area was reopened this morning. That is the good news. The bad news is lack of snow on the sides of the road.
Another rain event will hit the LA area later this week and move north with warm rain and high amounts with over a foot of rain predicted between Thursday and next week.
A common denominator of these rain storms are warm temps and probable snow melting rain in the high altitudes. If that happens above the Orovilled Dam, the flow into the lake could be very high.
No boats or jet skis on Clear Lake for 60 to 90 days due to high water levels.
Lake Berryessa hit the over flow earlier this week and will be over flowing with this new storm. So it will be overflowing into Putah Creek which as about as high as it can get without flooding.
There are flash flood alerts on the California Delta later this week.
Most if not all water reservoirs in the N Bay and other areas are overflowing or will be after this storm hits.
So in the Bay area we have three problems:
1. More rain coming in at least 2 storms.. No place for that rain in our reservoirs and the saturated land in the North bay Area.
3. The over taxed and old levees in the delta area with all the water flowing into the Delta from the past and coming rains and the releases from the filled reservoirs. They plan to release over max amounts from the Oroville Dams and other dams. The good news re tides. We will have normal high tides and the dangerous high King Tides season is over.
There are several dams that feed the Guadalupe River watershed in the southern Bay Area. I believe all the dams up in the hills of that watershed—Almaden, Calero, Guadalupe, and Lexington—are running effectively at capacity right now and the waters are going over the spillways. Let’s hope Guadalupe River flood control project completed nine years ago holds.
Your dam report is similar to what/where, we are at in the east bay and North bay.
This weeks rain will test our dams, roadways and bridges, many of which have been neglected for a decade or more.
Stay safe and keep us posted re what is happening in your area, the next few storms.
“Do the dam operators not watch the weather? With today’s technologies everyone knows the weather conditions 10+ days out. It’s not rocket science. If big rains come, which they do this time of year... duuuuuuh.... then lower the water level BEFORE the rains.”
Part of the answer to your question, “Who is doing the weather forecasts. The state or feds or some semi news organization with loyalty to the rats in Sac. town and the Gorebull Warming Pyschos.”
Channel two/Fox in the Bay area has switched from their normal forecasters to another one this week.
Many vineyard owners and wine makers if they can afford the private forecasters use them. Many set up their own weather stations in the vineyards and wine crush facilities for accurate rain and temp levels for those locations in real time. Then. that data is accurate for their needs, and often it is tied into a regional program for more reliable ontime data and predictions.
The heavy duty construction people pay big monthly payments to non government weather forecasters. If you listen to the government bs, you could end up some very expensive and heavy duty stuff stuck in a mud abyss for a long time. From what I hear from these people, they are not planning to start any heavy duty construction until about Easter. That covers the bay area to the Sierras and north on both sides of California to the Oregon/Cal border.
Apparently, their buds down south state are going into a similar holding pattern as that area may get hit by a lot of rain. The first of these storms will be hitting the LA area this week and moving north. Besides enough water to endanger frogs and fish, the rain is warm and melts snow.
We have so many microclimates in the Bay Area, any forecast from SF or Sac often has little bearing in other areas. Some of my offspring gave me an Acurite weather station about 16 months ago and installed data collection drone of top of a fence post 30’ from the station by my lazy boy. Now, we know what the temp is at that side of our house and how much rain since midnight each day. Seldom is that temp the same as Accuweather and other Android sources. The variance can be minimal to up to 8-10 degrees differance.
Local weather thugs don’t like to disclose where their data systems are, often to protect their Gorebull warming scams.
Lets hope so for the people below those catchement areas.
It’s good to know those gates work.
Still, I think controlled release from Shasta is limited to under 100,000cfs.
With Berryessa, Oroville and Folsom all releasing water, we’ll see it the Sacramento river and Yolo bypass.
