Lake Berryessa water level
Putah Creek · California · operated by USBR / Solano Project (Monticello Dam)
By Michael, independent developer behind zovo.one. Readings pulled live from the same CDEC feed the operator reports to.
Lake Berryessa is 87% full as of Nov 4, 2026, per CDEC data; 12.7 ft below full pool.
Is that normal for the date?
At 427.35 ft, Lake Berryessa is higher than 69% of Novembers in 42 years of daily record.
The median for this date across 42 years is 421.66 ft, so this is +5.69 ft against the lake’s own history. Placed on a quantile ladder built from 11,299 daily readings published by CDEC for site BER, 1985-01-01 to 2026-08-06. This reservoir typically peaks in February and bottoms out in December.
Lake Berryessa today: level, trend, source and access
Level against full pool
On Nov 4, 2026 the surface sat at 427.4 ft, 12.7 ft below the full-pool mark of 440 ft. It held 1,320,603 acre-feet of its 1,522,777 acre-foot capacity (87% full), so it needs about 202,000 acre-feet more to fill. CDEC put its storage at 117% of the historical average for Nov 4, at or above a normal year for the date. Of the 12 California lakes on this site with a live percent-full reading, it ranks 2 of 12.
Trend
Between Oct 6 and Nov 4 (29 days) the level fell 1.0 ft, about 0.3 ft a week. The high in that window was 428.4 ft on Oct 6 and the low was 427.4 ft on Nov 4. In the last 7 days it fell 0.2 ft. The last 24 hours moved it down 0.07 ft.
Data source
The elevation comes from California Data Exchange Center (CDEC) station BER (California Department of Water Resources), last reported Nov 4, 2026. Percent full is CDEC storage divided by the capacity CDEC lists for the dam. Feet from full pool, the trend and the figures above are computed from that reading and the published full-pool elevation; none is typed by hand. USBR / Solano Project (Monticello Dam) runs the dam on the Putah Creek.
Recreation status
Status: healthy. At 87% full it is 27.0 points above 60%, the line above which most ramps stay in the water, so a normal ramp day is likely. Ramps still close on their own schedules, so check yours with USBR / Solano Project (Monticello Dam). If the 30-day pace of 0.3 ft a week down held, the surface would be near 426.4 ft in four weeks. Releases and rain change that quickly.
To see where today sits against every monthly reading since 1957, the Lake Berryessa water level chart plots the whole CDEC storage record and ranks the latest month against the same month in every year.
Check an elevation against full pool
For readers outside the U.S., the surface of Lake Berryessa is about 130.3 m above sea level, and full pool is about 134.1 m.
Check any elevation yourself. Type a level in feet above sea level (a ramp cutoff, a marina mark) to see how far it sits below full pool and in meters.
