How many lakes and reservoirs in Kansas are tracked here?

20, of which 20 report a current pool-elevation reading. The rest report storage only, or lack a fresh reading and are not published.

Which Kansas lakes report a %-full figure?

9 of Kansas'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.

USGS Water Services and USACE CWMS Data, both public domain. See the methodology page for the exact endpoints and update cadence.
