Maine has 3 lakes and reservoirs tracked here — 3 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.

- 3, of which 3 report a current pool-elevation reading. The rest report storage only, or lack a fresh reading and are not published.
- Which Maine lakes report a %-full figure?
- None of Maine'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.
