About this gauge's record
USACE's continuous elevation record for this project begins in 2015 (2 tracked series for this project).
The dam behind Stennis Lock and Dam
Stennis Lock and Dam is held back by John C. Stennis Lock and Dam (also recorded as Columbus Lake; Columbus) , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 82 ft high and running 1,000 ft along its crest , built across TOMBIGBEE in Lowndes County , near COLUMBUS . It was completed in 1980 , and is owned by USACE - Mobile District (a federal owner) , to a design credited to CESAM.
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 . It also serves navigation;recreation.
Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. The spillway opening is 300 ft wide.
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.
At its normal pool the reservoir covers about 8,910 acres. NID records a maximum storage of 59,483 acre-ft against a normal storage of 59,483 acre-ft. Its maximum discharge capacity is 628,200 cubic feet per second. It is regulated by MS DEPARTMENT OF ENVIRONMENTAL QUALITY.
