About this gauge's record
USACE's continuous elevation record for this project begins in 2013 (2 tracked series for this project).
The dam behind Demopolis Lock and Dam
Demopolis Lock and Dam is held back by Demopolis Lock and Dam (also recorded as Demopolis Lake) , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 63 ft high and running 1,770 ft along its crest , built across TOMBIGBEE RIVER in Marengo County , near DEMOPOLIS . It was completed in 1955 , 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 ungated: once the pool reaches the crest, water leaves on its own and the operator cannot hold it back. The spillway opening is 1,485 ft wide. Its outlet works use none0.
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 10,000 acres. NID records a maximum storage of 150,000 acre-ft against a normal storage of 120,000 acre-ft. Its maximum discharge capacity is 88,000 cubic feet per second.
