Kansas has 20 lakes and reservoirs tracked here — 20 with a current elevation reading; 9 report a %-of-conservation-pool-full figure, 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.

Big Hill Lake is held back by Big Hill Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 83 ft high and running 3,902 ft along its crest , built across BIG HILL CK in Labette County , near CHERRYVALE . It was completed in 1981 , and is owned by USACE - Tulsa District , to a design credited to CESWT.
Its recorded primary purpose is flood risk reduction — the pool is drawn down between storms so there is empty space waiting for the next flood, which is why this level can fall in dry weather and climb sharply after rain. Its spillway is ungated: once the pool reaches the crest, water leaves on its own and the operator cannot hold it back. NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in.

Cedar Bluff Reservoir is held back by Cedar Bluff Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 202 ft high and running 12,560 ft along its crest , built across SMOKY HILL RIVER in Trego County , near SCHOENCHEN . It was completed in 1951 , and is owned by BUREAU OF RECLAMATION , to a design credited to BUREAU OF RECLAMATION.
Its recorded primary purpose is flood risk reduction — the pool is drawn down between storms so there is empty space waiting for the next flood, which is why this level can fall in dry weather and climb sharply after rain. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in.

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.
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.
