Lake Berryessa Statistics, 10/20/26
Lake Berryessa water level has now dropped to 427.7 feet - 12.3 feet below Glory Hole.
The lake output has dropped rapidly to an average 200 cubic feet per second or 396 Acre-Feet per Day due to decreased irrigation needs.
The lake holds 1,551,292 when full (flowing over the lip of Glory Hole).
Lake capacity is now at 1,327,082 Acre-Feet or 85.5%.
The surface water temperature continues to slowly drop. It is now at 69 degrees from the
surface to 40 feet down.
With weather changes coming up, it's almost time to open a Glory Hole Watch 2027 file!

Out & About Around Lake Berryessa with Evan & Justin on October 17, 2026
Riding uphill on their electric mountain bikes made it a lot easier to get to the top of Berryessa Vista, a seldom visited Regional Park and Open Space District (RPOSD) park.to get some great panoramic shots of the lake - also of the high tech cell tower up there.
Then onto Justin's boat at Pleasure Cove for a photo of their new huge new covered dock and a tour of the lake which produced some nice shots, including happy fishing families.
Finally to Steele Canyon Campground for manager Rocky Costanzo's 3rd Annual Trailer &Treat event. Rocky will move the many skeletons up to his house on Rimrock for Halloween.

Conclusion: Napa County needs a Wildfire Prevention and Mitigation Measure on the 2027 ballot.
Napa County Measure "W", 2027
Strictly managed by the Napa Communities Firewise Foundation.
https://napafirewise.org/

Election time brings out some of the most annoying people to make pointless negative comments on social media. Some of the worst are the doctrinaire "no new taxes at any cost" folks. Below are some actual moronic social media comments from Napa voters opposed to Measure B. They serve as a few examples of the "Many Morons Theory of Social Responsibility" described below..
We always underestimate the number of stupid people in circulation, and their stupidity is completely independent of education or social standing. Cipolla argued that society declines when intelligent leaders fail to keep the "fraction of stupid individuals" from destroying collective societal value.

Talk about Missing the point!
As Mr. Rogers used to sing:
"It's a beautiful day in this neighborhood, A beautiful day for a neighbor. Would you be mine? Could you be mine?"
I'm not sure the folks quoted below would be good neighbors.
"The people that live in those areas should be taking care of their own property."
"If it raises taxes, I don't care how beneficial it is, it is a hell NO for me."
"The only ones that would benefit are private landowners that don't want the cost to maintain their own property."
"I’m not in a fire prone area and do not want to support your choice of residence."
"No on B, no more taxes! Enough is enough!"
"If you're wealthy enough to build, and rebuild, in the hills you can pay for your own property maintenance, defensible space and chipping."
Many Morons Theory of Social Responsibility
Based on The Basic Laws of Human Stupidity by Italian economist Carlo M. Cipolla. Cipolla broke society down into four quadrants based on a person's behavior and its net impact on social responsibility/welfare.
Intelligent People: Actions benefit themselves and benefit others. Drives societal progress.
Helpless People (Naïve): Actions benefit others but harm themselves. Easily exploited by others.
Bandits: Actions benefit themselves at the expense of others. Creates a zero-sum society.
Stupid People ("Morons"): Actions cause losses to others while gaining nothing (or even losing) themselves. The ultimate threat to society.

For several years, The Lake Berryessa News has followed Tim Carl's reporting on the Napa Wine Industry in Napa Valley Features. I personally don't drink much wine, nor do I care about "wine culture". Many of the folks I know, especially the younger people, don't either. My hierarchy of choice is Manhattan, Margarita, Gin & Tonic, Butter Chardonnay, Pina Colada, Mojito...
But I do care about Napa County. Tim has been writing in-depth analyses of Napa wine issues for a few years. An introduction to the latest article is copied below. But what about California and the rest of the country? In a non-scientific approach, I just asked the Google AI to review the situation. Below is that response.

The Downturn We Reported and the Shocks We Didn't See Coming
by Tim Carl
https://napavalleyfocus.substack.com/
https://napavalleyfocus.substack.com/p/under-the-hood-the-downturn-we-reported
For three years this column has reported the same finding: Napa’s wine economy was not passing through a cycle it would exit on its own but through a structural reset it would have to clear. The data pointed away from recovery and toward clearing — the slow work of grinding through excess supply, excess capacity and assumptions built for a demand environment that no longer exists — and we reported it that way. What has changed in the second half of 2026 is not the data’s direction. It is the visibility.
The contraction that earlier showed up in models and forward scenarios has moved into plain view — in shipment data, in tasting-room receipts, in the decisions of the valley’s largest operators and now, in the one measure that turns last, the count of active winery licenses. It is also arriving faster than the demand decline alone would explain because a second set of pressures has landed on top of it. Those pressures did not begin in wine, and most of them the earlier reporting did not anticipate. Together, they have removed the slack that might have slowed the descent.

Google AI Question: Wine Economics in the USA
The U.S. wine industry generates a massive economic impact of over $323 billion annually, though it faces ongoing volume declines and shifting consumer habits. The American wine industry accounts for a $323.55 billion economic output across all 50 states and D.C. The sector supports roughly 1.75 million jobs total (including direct, supplier, and induced roles) and provides $102.14 billion in aggregate wages.
Vineyard and winery visits total roughly 74 million tourist trips a year, injecting billions into local hospitality and generating over $46 billion in total business taxes. California dominates domestic production, accounting for roughly 85% of U.S. volume and tens of billions in economic activity, followed by strong regional markets in Washington, New York, Oregon, and Texas.
The U.S. market is experiencing consecutive annual volume drops driven by younger generations consuming less alcohol and rolling control-state data pointing to further retraction. Unlike standard agriculture where higher crop yields boost profit, viticulture often follows an inverse rule—restricting vine yields concentrates flavor for luxury tier pricing, whereas over-producing dilutes quality and collapses the per-ton price. Wineries face rising operational costs and intense competition from foreign imports (which make up roughly a third of all wine consumed in the U.S.), forcing thousands of acres of wine grapes to be pulled out in major regions like Central California.
Google AI Question: Wine Economics in California
California's wine industry generates roughly $73.0 billion in annual state economic activity and produces about 80% to 81% of all wine in the United States. Generates $170.5 billion in total annual economic activity nationwide and $73.0 billion directly within California. Supports 1.1 million jobs across the U.S., including roughly 422,000 jobs within California. Contributes $25.9 billion in annual wages inside the state and yields $7.9 billion in state, local, and federal taxes. Spans over 500,000 vineyard acres across nearly 50 California counties with thousands of active winery facilities. Global and domestic wine consumption has dropped from post-pandemic peaks (such as the 2021 high) as younger consumers drink less alcohol and shift toward alternatives like ready-to-drink cocktails or cannabis.
High production costs in the U.S. make it difficult to clear excess inventory, compounded by cheap bulk wine imports from overseas competitors. International trade friction and retaliatory tariffs have significantly squeezed foreign shipments, forcing some local growers to let crops wither or repurpose vineyard land entirely.
Google AI Question: Wine Economics in Napa, California
Napa Valley's wine economy is undergoing a structural market reset in 2026, marked by falling grape values, lower tourism volume, and rising compliance costs.
Grape values fell to $968.7 million in 2025.
Tasting-room median orders dropped to $266.
Shipment volumes declined by 8%.
Average bottle prices rose to $99.97.
Active winery licenses peaked and began falling.
Regulatory compliance costs reach $1,745 per acre.
Water and sustainability fees increased significantly.
Supply, energy, and labor inflation squeezed margins.
Younger demographics show lower overall alcohol consumption.
Wineries add non-wine events and entertainment.
Operators prune portfolios and cut production capacity.
Vineyards reduce acreage to match lower buyer demand.
Venues experiment with complimentary or discounted tastings.

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/
