The dam behind Millwood Dam
Millwood Dam is held back by Millwood Dam (also recorded as Millwood Lake) , a concrete structure , standing 88 ft high and running 14,500 ft along its crest , built across LITTLE in Little River County , near FULTON . It was completed in 1966 , and is owned by USACE - Little Rock District (a federal owner) , to a design credited to CESWT, CESWT.
Its recorded primary purpose is flood risk reduction — the pool is drawn down between storms so there is empty space waiting for the next flood, which is why this level can fall in dry weather and climb sharply after rain . It also serves flood risk reduction;recreation;water supply.
It is founded on rock;soil, with a earth core. NID records no spillway for it. The spillway opening is 0 ft wide.
NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in.
At its normal pool the reservoir covers about 29,000 acres. NID records a maximum storage of 1,854,930 acre-ft against a normal storage of 172,000 acre-ft. Its maximum discharge capacity is 473,300 cubic feet per second.
