The dam behind Lock and Dam 24 Pool
Lock and Dam 24 Pool is held back by Mississippi River Lock and Dam 24 (also recorded as Mississippi River) , a concrete structure , standing 76 ft high and running 4,584 ft along its crest , built across MISSISSIPPI RIVER in Calhoun County , near CLARKSVILLE . It was completed in 1940 , and is owned by USACE - St. Louis District (a federal owner) , to a design credited to CEMVS.
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 is founded on rock;soil, with a metal core. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. The spillway opening is 1,200 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 13,000 acres. NID records a maximum storage of 125,363 acre-ft against a normal storage of 125,363 acre-ft. Its maximum discharge capacity is 364,000 cubic feet per second.
