NGVD 1929 (CDEC station metadata). The chart uses CDEC’s DATE TIME series date; OBS DATE is preserved in the table. Missing values are omitted, and the connecting line does not imply measurements on missing dates.

Read this series carefully

The elevation is CDEC sensor 6 in feet. We do not infer percent full from this number or compare it directly with another reservoir’s datum. Check the station’s metadata for revisions and source context.

The series does not report ramp access, swimming conditions, a forecast or available drinking-water supply. Use the operating agency’s notices for access and conditions.

Retrieved 2026-11-12T19:53:46.658Z. Daily refresh target; previous successful readings are retained if a source check fails.
