Frequently asked questions

How many lakes and reservoirs in California are tracked here?
67, of which 61 report a current pool-elevation reading. The rest report storage only, or lack a fresh reading and are not published.
Which California lakes report a %-full figure?
None of California's lakes in this dataset currently have a source-provided %-full figure — we show the bare level rather than estimate one.
Where does the data come from?
USGS Water Services and USACE CWMS Data, both public domain. See the methodology page for the exact endpoints and update cadence.
