Don Pedro Reservoir water level
Tuolumne River · California · operated by Turlock/Modesto Irrigation District (Don Pedro Dam)
By Michael, independent developer behind zovo.one. Readings pulled live from the same CDEC feed the operator reports to.
Don Pedro Reservoir is 73% full as of Nov 3, 2026, per CDEC data.
Is that normal for the date?
At 781.74 ft, Don Pedro Reservoir is higher than 63% of Novembers in 42 years of daily record.
The median for this date across 42 years is 773.10 ft, so this is +8.64 ft against the lake’s own history. Placed on a quantile ladder built from 11,894 daily readings published by CDEC for site DNP, 1985-01-01 to 2026-08-06. This reservoir typically peaks in June and bottoms out in January.
Don Pedro Reservoir today: level, trend, source and access
Level against full pool
On Nov 3, 2026 the surface sat at 781.7 ft, 48.3 ft below the full-pool mark of 830 ft. It held 1,474,669 acre-feet of its 2,030,000 acre-foot capacity (73% full), so it needs about 555,000 acre-feet more to fill. Of the 12 California lakes on this site with a live percent-full reading, it ranks 4 of 12.
Trend
Between Oct 5 and Nov 3 (29 days) the level fell 4.5 ft, about 1.1 ft a week. The high in that window was 786.3 ft on Oct 5 and the low was 781.4 ft on Oct 30. In the last 7 days it fell 0.1 ft. The last 24 hours moved it up 0.24 ft.
Data source
The elevation comes from California Data Exchange Center (CDEC) station DNP (California Department of Water Resources), last reported Nov 3, 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. Turlock/Modesto Irrigation District (Don Pedro Dam) runs the dam on the Tuolumne River.
Recreation status
Status: healthy. At 73% full it is 13.0 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 Turlock/Modesto Irrigation District (Don Pedro Dam). If the 30-day pace of 1.1 ft a week down held, the surface would be near 777.4 ft in four weeks. Releases and rain change that quickly.
To see where today sits against every monthly reading since 1970, the Don Pedro Reservoir 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 Don Pedro Reservoir is about 238.3 m above sea level, and full pool is about 253.0 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.
