The dam behind Mont Pt Lock & Dam
Mont Pt Lock & Dam is held back by Montgomery Point Lock and Dam , a concrete structure , standing 55 ft high and running 843 ft along its crest , built across WHITE in Desha County , near NA . It was completed in 2004 , and is owned by USACE - Little Rock District (a federal owner) , to a design credited to CESWL.
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 concrete core. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. The spillway opening is 500 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 613 acres. NID records a maximum storage of 10,595 acre-ft against a normal storage of 7,452 acre-ft. Its maximum discharge capacity is 0 cubic feet per second.
