Arbuckle Lake is held back by Arbuckle Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 150 ft high and running 1,890 ft along its crest , built across ROCK CREEK in Murray County , near DOUGHERTY . It was completed in 1966 , and is owned by BUREAU OF RECLAMATION , to a design credited to USDA NRCS. 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.

Atoka Reservoir is held back by Atoka , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 88 ft high and running 850 ft along its crest in Atoka County . It was completed in 1957 , and is owned by Oklahoma City Water Utilities Trust , to a design credited to C. E. BRETZ. Its recorded primary purpose is water supply — delivering water to its customers comes first, so drawdown here follows demand as much as it follows rainfall. 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. Its most recent condition assessment was fair: sound under normal loading, though a rare or extreme event could expose a deficiency.

Chouteau Ld17 is held back by Chouteau Lock and Dam , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 53 ft high and running 11,690 ft along its crest , built across VERDIGRIS RIVER in Wagoner County , near OKAY . It was completed in 1970 , and is owned by USACE - Tulsa District , to a design credited to CESWT. Its recorded primary purpose is navigation — the pool is held inside a narrow band to keep a navigable depth, so large swings are rare by design. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. NID classes it significant hazard potential: a failure would be expected to damage property and infrastructure rather than cost lives. It is a consequence rating, not a condition rating.

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.

Tenkiller Lake is held back by Tenkiller Ferry Dam , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 197 ft high and running 4,940 ft along its crest , built across ILLINOIS RIVER in Sequoyah County , near GORE . It was completed in 1952 , 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 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.

Tom Steed Lake is held back by Mountain Park Dam , a concrete structure , standing 133 ft high and running 535 ft along its crest , built across WEST OTTER CREEK, NORTH FORK OF RED RIVER in Kiowa County , near SNYDER . It was completed in 1975 , and is owned by BUREAU OF RECLAMATION , to a design credited to BUREAU OF RECLAMATION. Its recorded primary purpose is water supply — delivering water to its customers comes first, so drawdown here follows demand as much as it follows rainfall. 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.

Webbers Falls Ld16 is held back by Webbers Falls Lock and Dam , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 84 ft high and running 4,370 ft along its crest , built across ARKANSAS RIVER in Muskogee County , near WEBBERS FALLS . It was completed in 1970 , and is owned by USACE - Tulsa District , to a design credited to CESWT. Its recorded primary purpose is navigation — the pool is held inside a narrow band to keep a navigable depth, so large swings are rare by design. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. NID classes it significant hazard potential: a failure would be expected to damage property and infrastructure rather than cost lives. It is a consequence rating, not a condition rating.

Frequently asked questions

How many lakes and reservoirs in Oklahoma are tracked here?
51, of which 44 report a current pool-elevation reading. The rest report storage only, or lack a fresh reading and are not published.
Which Oklahoma lakes report a %-full figure?
34 of Oklahoma'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.
