Good to see all the reservoirs filling up, but, I'll be glad once the roads have dried out a bit.

How about another lake I've sailed before, 25 years since last fillup.
23% full in December, the county had cloud seeded Lopez Lake this year.
I would like to see these numbers on how effective seeding was.

Lake Berryessa Statistics (4/2/23)
The lake level has risen slowly another inch yesterday, to 429.4 feet - 10.6 feet below Glory Hole, a 35.4 foot rise since its low of 394.0 feet on December 1, 2022. Rainfall at the dam has reached 40.97 inches. As a comparison, rainfall at Cobb Mountain was a total of 84.5 inches on 3/30/23 and is slowing down too. March rainfall hit a 10 year record of 12.54 inches. The previous highest March total since 2010 was 12.4 inches in 2011.
After four dry days, the rainfall from 3/27 to 4/2 was only 1.6 inches. The lake rose 1.6 feet during that same time, so we are in the 1 foot rise for 1 inch of rain range. But with only light rain and mostly dry weather predicted for the next several weeks, the lake will definitely NOT hit Glory Hole this year, but hopefully more than 430 feet. That would be a very good result.
Most long-term Lake Berryessa watchers consider that, from a practical viewpoint, 430 feet and above is a full lake. Summer should be an excellent year for fun at the lake. The other good news is that, with the continuing light rains, irrigation water will not be as necessary during this Spring, so the lake won’t start to drop until later.
The Gamble Gauge has reached 87.4% capacity (1,356,430 A-F). Dam output is still at 45 cubic feet per second (CFS), water - the lowest allowed by law and contract. The release is not affecting the lake level in any significant way.
The surface of the lake warmed up a bit to around 55 degrees but is still at around 50 degrees from 70 feet down.

Maybe my last update, IF the rain quits
I even still have a chance to win
Lake Berryessa Statistics (4/8/23)
Lake Berryessa Creeps Up To 430.2 feet - 9.8 feet below Glory Hole!
The lake has stopped rising. The rain has stopped raining. A good summer is soon coming!
Due to the lake's stability and no really exciting news to report about the lake level, I will not be posting my report on a daily basis. For real time information see
https://www.scwamonitoring.com/LakeBerryessa/.
With only .09" of light rain since March 31 with a season total of 41.06" and no rain in sight, it's only a short time until the lake level starts dropping. It should drop more slowly this year since, due to the longer rainy season, significant agricultural use may be delayed a few weeks.
On historical average (see chart below) the lake only drops about 15 - 20 feet per summer. We should have plenty of water to enjoy for years - even if another drought begins.
The Gamble Gauge has reached 88.3% capacity (1,369,691 A-F). The surface of the lake definitely warmed up during the last few days to 56 degrees but is still at around 50 degrees from 70 feet down.

I'm calling it here,
Lake Berryessa also calls it as full as it is gonna get.
The Lake Berryessa News: April 19, 2023
The Excitement of Lake Berryessa Rising Is Over,
But the Excitement of a Great Summer at Lake Berryessa Is Rising!
The lake has stopped rising.
The rain has stopped raining.
The creeks have stopped flowing.
A good summer is soon coming!
The lake has essentially stopped rising, barely hitting 430.8' today - 9.2' below Glory Hole - a rise of less than 4" in the last 7 days, and only a half-inch a day for the last 3 days. That's also a near record rise of 36.8' since its low of 394 feet on 12/1/22. Most long-term Lake Berryessa watchers consider that, from a practical viewpoint, 430 feet and above is a full lake.
The rain has stopped raining. A record 2022-2023 rainfall season of 41.1 inches is the second highest since 1998 (46.3"). The lake should drop more slowly this year since, due to the longer rainy season, significant agricultural use may be delayed a few weeks. The lake out put has risen from the minimum 45 cfs required by law and contract to 125 cfs driven by Solano County agricultural requirements as the weather dries and the growing season begins.
On historical average (see chart below) the lake only drops about 15 to 20 feet per summer. We should have plenty of water to enjoy for years - even if another drought begins.
Lake water temperatures have begun to rise noticeably to above 60 degrees at the surface, but not swimming water yet. Considering that summer water temperatures hit 80+ degrees, there's a bit of a way to go. The water temperature remains around 51 degrees from 70 feet to the bottom.
Lake Berryessa also calls it as full as it is gonna get.

The lake has stopped rising, barely hitting 430.91' - 9.09' below Glory Hole - and has not changed in 5 days. That's also a near record rise of 36.91' since its low of 394 feet on 12/1/22.
Still filling ?? "R" next week

Snow Mountain NM may drain into the lake, but not anything from the Sierras

The big thing is there are likely committments for the water than will lower it before any potential melts arrive to raise it again, so it's like to have peaked.

Lake Berryessa Statistics: April 30, 2023
The lake level has stopped rising and started falling after staying at 430.91' - 9.09' below Glory Hole - for 5 days. That's also a near record rise of 36.91' since its low of 394 feet on 12/1/22.
The rain stopped raining. There has been no measurable rain since April 6. A record 2022-2023 rainfall season of 41.1 inches is the second highest since 1998 (46.3"). The scattered showers predicted for the next few days will have no effect on lake levels. The lake level has started decreasing because the dam output has risen from the minimum 45 cfs required by law and contract to 280 cfs - driven by Solano County agricultural requirements as the weather warms and the growing season begins.
The Gamble Gauge (lake capacity) has dropped from 89.23% on 4/29 to 89.20% today - a decrease of 462 acre-feet.
On historical average the lake only drops about 10 - 15 feet per summer. We should have plenty of water to enjoy for years - even if another drought begins.
It only took a few days for lake water temperatures to rise noticeably to 70 degrees at the surface to 10 feet down. The water temperature rose to around 52 degrees from 70 feet to the bottom.

Berryessa is looking promising for a spill this year? Lacks less than 4 feet?

Lake Berryessa Statistics: March 2, 2024
Rainfall has been light at the lake. The lake has only risen about 2 inches in the last two days. One reason is the 5 day dry spell with warm sunny weather we just enjoyed. The soil has dried out and needs to be re-saturated before significant runoff will begin again. Also, the hills are green and blooming, which means that the growing plants are also using the rain that falls on the hills.
Rainfall predictions for the next 24 hours of this storm are moderate for the Lake Berryessa watershed. It is unlikely but possible that this last day of the storm will push the lake over Glory Hole, but we'll see.
The Lake Berryessa water level is now at 436.9 feet (3/2/24 - 9 AM) only 3.1 feet below Glory Hole!
At this level the lake rises 7 inches for every inch of rain. So, 3.1 feet of rise would require 6 more inches of rain. (3.1 feet of rise needed times 12 inches per foot equals 37.2 inches rise needed divided by 7 inches per inch of rain equals 5.3 inches of rain needed.)
The season total rainfall at Monticello Dam is now at 21.7 inches.
Getting close, maybe two storms away

Glory Hole Watch 3/10/24
Lake Level = 439.0 feet, (8 AM)
1 foot below Glory Hole
Rainfall has reached 23.84 inches on .19 inches added yesterday. Essentially zero rainfall during the 5 days before that.
At least 2 inches of rain still needed to make it overflow this year. Still possible?
My latest article Glory Hole article was published at the Napa Valley Features site. Check out a free subscription.
