How many lakes and reservoirs in Nevada are tracked here?

9, of which 4 report a current pool-elevation reading. The rest report storage only, or lack a fresh reading and are not published.

Which Nevada lakes report a %-full figure?

None of Nevada'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.

Nevada lake & reservoir water levels

9 lakes tracked · 4 with a current elevation reading · USGS Water Services + USACE CWMS Data

Nevada has 9 lakes and reservoirs tracked here — 4 with a current elevation reading, from USGS Water Services and USACE CWMS Data. Sort the table by level, storage, %-full, or trend, then open any lake for its full elevation-with-datum, trend sparkline, storage, and source-and-vintage stamp. Figures are provisional readings for reference — not for navigation or safety decisions.
