The dam behind Blue Mountain Dam
Blue Mountain Dam is held back by Blue Mountain Dam (also recorded as Blue Mountain Lake) , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 115 ft high and running 2,800 ft along its crest , built across PETIT JEAN in Yell County , near DANVILLE . It was completed in 1947 , and is owned by USACE - Little Rock District (a federal owner) , to a design credited to CESWL.
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, with a earth core. 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 150 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 2,910 acres. NID records a maximum storage of 258,000 acre-ft against a normal storage of 25,000 acre-ft. Its maximum discharge capacity is 76,300 cubic feet per second.
