Frequently asked questions
- How many lakes and reservoirs in Arkansas are tracked here?
- 51, of which 51 report a current pool-elevation reading. The rest report storage only, or lack a fresh reading and are not published.
- Which Arkansas lakes report a %-full figure?
- 10 of Arkansas's lakes have 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.
