Answers

California reservoir level questions

Where are California reservoir levels posted?

This page lists every CDEC reservoir station with a recent reading, and each lake page links its station.

How full is Shasta Lake?

53% of capacity on the CDEC report.

What does percent of average mean?

Storage compared with the historical average for the same date, as CDEC reports it.

Why are some lakes missing?

Only reservoirs with an active CDEC or USGS station are listed.

How often do readings change?

CDEC posts daily storage; USGS lake gauges update every 15 minutes and refresh here hourly.

What is an acre-foot?

The water needed to cover one acre one foot deep, about 326,000 gallons.

Do low levels close launches?

Often; check the launch operator before driving.

Where are California river flows?

Each stream page and county page carries the live USGS readings.
