Lake Berryessa Statistics 5/10/26

Lake Berryessa water level has remained relatively constant during the last 5 days - dropping only an inch. It now stands at 438.7 feet - 1.3 feet below Glory Hole.

Rainfall at Monticello Dam remains at 24.75 inches.

The lake output has risen to 375 cfs (743 A-F per day). The highest output during the summer averages about 700 cfs (1,387 A-F per day).

The runoff at the Geunoc measuring site is down to 54 cfs. Total runoff is at less than 25% of lake output so the lake level will continue to keep decreasing. This information will not really be relevant until the first rain in October.

When full (Glory Hole level) the lake contains 1,551,292 Acre-Feet of water.

Lake capacity is now at 1,529,083 Acre-Feet or 98.4%.

Water temperatures have risen to swimmable levels of almost 75 degrees.

Caltrans Silly Safety Signs Sprout!
by Peter Kilkus
Sprout: Verb: To appear suddenly or grow rapidly in number.

 
I'm a "keep your eyes on the road" kind of driver. I pay attention to the yellow lines in the middle of the road and the white lines on the right edge. I judge the state of the road far as I can see. But as I was driving to Napa a couple of weeks ago I noticed that my eyes were annoyingly pulled off the approaching road and drawn to hundreds of distracting bright yellow signs planted along the side of the road at a height above my normal field of view.
 
Even when I could clearly see a half-mile down the road, there was a sign. Too many signs were used to confuse people on simple curves. Most, if not all, the signs were clearly redundant (five arrow signs on a simple and visible curve) and unnecessary. A couple were hidden behind branches. Many other regular commute drivers have also complained. So I sent a formal complaint to Caltrans.
https://csr.dot.ca.gov/index.php/Msrsubmit

Nature of Situation: Too many new warning signs on Hwy 121 (Monticello Road) detracting from driver safety. There were many unnecessary new signs recently installed, almost all of which draw the drivers' eyes away from the road. They are annoying and redundant. Other residents have also complained to me about them.
 
 If you are as annoyed as many of the other local drivers, you can "Submit Customer Service Request" request at:
 
I received the following reply: "Thank you for contacting Caltrans. We value your request for service. Because your concern is a recommendation for alteration to existing infrastructure, your request has been referred to our Traffic Ops Division for review and feasibility; Please know that certain studies, assessments and determinations can take up to 6-months."
 
I also found this little paternalistic gem in the Caltrans manual:
 
"Caltrans warning signs, detailed in the California Manual on Uniform Traffic Control Devices (CA MUTCD), notify drivers of unexpected road conditions, hazards, or speed changes requiring caution...Their placement is determined by engineering studies to address hazards that are not immediately obvious to motorists."
 
Here is a sample from Nextdoor of what other drivers think (names not shown for privacy):
 
"Quite a few signs were put in the wrong place to actually help navigate the road. And some actually tell you to turn where there is no turn. Others tell you the road is to go one way, when in reality, it goes the other way. Trust the sign at night and you might go off the road."
 
"It goes way beyond that! They used to put arrows when there was truly a sharp turn. That was fine. Now there’s arrows for a tiny kink in the road. Just like new cars, the more info given to them from a source other than their brain, the dumber the driver gets!!!"
 
"Jesus Christ! I drove to Napa today for the first time in a while. Thank God for the 958 signs telling me to turn left or right since I couldn’t tell from the movement of the road. My personal favorite were the back to back 20 mph, no! 30 mph… No, wait, 20 mph signs. I’m seeing a circular saw in somebody’s future."
 
"I have 3 million miles as a professional motor vehicle operator. These signs are a distraction. They may as well put up spotlights in both directions. I will say they went in really fast."
 
"As someone who drives up and down 121, sometimes twice daily starting at 5 am and coming home at 11pm - they made my commute into town and back an hour each way over an almost 2 week stretch - hard to believe no one saw them going up."
 
"Section 2 and 5. California updated to the 2026 MUTCD rules, to comply with 2023 federal transportation guidelines. That’s where the excessive signage is originating. Government doing silly government things just like always."
 

https://dot.ca.gov/-/media/dot-media/programs/safety-programs/documents/ca-mutcd/2026/camutcd-2026-all.pdf

 
"I’m thankful for the signs because without them I would have never known which way to go when the road changed!" (satire)
 
"At night they're blinding! Who could possibly agree to such an absurd over use!? I understand it can be a dangerous road, but this overkill is beyond common sense! They have destroyed a beautiful country road drive!  I’m so glad to hear others similar reaction. I think if we could snag the right people who have some power, put them in a car and drive them up and down in the daytime and again at night, they would see what we're all flipping out about. We need help! This is just too intolerable."

Lake Berryessa Revialization Program Update

Readers may have seen a few articles about the situation at Lake Berryessa being reviewed by the Napa Board of Supervisors last week. Actually nothing of substance came out of that meeting since it was a simple discussion of the overall status of the resorts. The articles in the Register and Press Democrat contained several unusual reporting errors (misidentifying Camp Margaritaville Resorts as Margaritaville) or repititions of what has regularly been reported in The Lake Berryessa News.

A neighbor sent me a note say that her daughter had gone to Walmart and there was a guy collecting signatures against development at the lake. If you see someone doing this, let me know, as well as informing them that you support the Lake Berryessa Revitalization Program.

I responded that there have been Lake Berryessa anti-advocates working behind the scenes trying to undermine the Lake Berryessa Revialization Program for a couple of years. They attacked the Camp Margaritaville proposal for the rebuilding of the Steel Canyon Recreation Area at a Supervisors' meeting more than a year ago. At the time I wrote several reports debunking their false claims and their humorous feelings of 'cringeness'."

Definition: Cringy" (or cringey) is an informal adjective describing something that causes acute embarrassment, awkwardness, or discomfort, often making a person feel embarrassed on behalf of someone else. It is synonymous with "cringeworthy" and is frequently used to describe uncomfortable social situations, bad performances, or unnatural behavior.

Paul Franson's weekly Napa Valley Life is jam-packed with interesting information about Napa Valley events and out-and abouts. His links to the ubiquitous food truck culture makes my mouth water.

Where is what food truck?

It’s very challenging to keep track of the many food trucks in our community, and it’s not just because they have wheels. They change their offerings, disappear for private events and move to different locations. It’s so challenging that I’m happy to see a new website that tracks them.

Lake Berryessa Data Sources

There are many sources of Lake Berryessa water and weather conditions available. The Solano County Water Agency site is good for real-time graphs of level, capacity, and water temperature. The California Data Exchange Center has data going back decades for level, capacity, capacity change, dam outflow, dam inflow, and rainfall. Anyone can research their own data and create custom charts. This is the source of many of the charts on the Lake Berryessa News website.

********
An upgraded wildfire alert camera system will be keeping watch on Napa County day and night and notifying Cal Fire crews of potential fires. Twenty cameras will be part of a system that will use artificial intelligence and other technologies to identify fire and smoke. If they detect something, an alert will sound in the Cal Fire emergency command center near St. Helena.

Cal Fire has made a large investment into the ALERTCalifornia system, partnering with UC San Diego. There are 1,000 cameras across the state and Napa County is one of the test models.
Cameras can see 60 miles during the day, and this can increase to 120 miles on clear nights, with the changes in the air. The system can differentiate among smoke, clouds and dust. A link to this camera system and other relevant weather data is available on the Lake Berryessa News website at: http://www.rntl.net/lake-berryessa-cams/

This website was created by Doug Kunst. It is an amazing resource for Lake Berryessa fire cameras and weather. His business website is http://www.rntl.net/
