Frequently asked questions

How many lakes and reservoirs in Louisiana are tracked here?
37, of which 37 report a current pool-elevation reading. The rest report storage only, or lack a fresh reading and are not published.
Which Louisiana lakes report a %-full figure?
1 of Louisiana's lakes has a real, source-provided %-of-conservation-pool-full figure (from USACE); the rest show the bare level because their source does not publish that comparison.
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.
