The dam behind Lock and Dam 25 Pool
Lock and Dam 25 Pool is held back by Mississippi River Lock and Dam 25 (also recorded as Mississippi River) , a concrete structure , standing 75 ft high and running 26,400 ft along its crest , built across MISSISSIPPI RIVER in Lincoln County , near WINFIELD . It was completed in 1939 , 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 soil, with a earth;metal core. NID records no spillway for it. The spillway opening is 0 ft wide. Its outlet works use none0;roller0.
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 176,000 acre-ft against a normal storage of 176,000 acre-ft. Its maximum discharge capacity is 0 cubic feet per second.
