The dam behind Whitlow Ranch Dam
Whitlow Ranch Dam is held back by Whitlow Ranch Dam (also recorded as Whitlow Ranch Reservoir) , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 149 ft high and running 837 ft along its crest , built across QUEEN CREEK in Pinal County , near QUEEN VALLEY . It was completed in 1959 , and is owned by USACE - Los Angeles District (a federal owner) , to a design credited to CESPL.
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;irrigation.
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 355 ft wide. Its outlet works use none0.
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 1 acres. NID records a maximum storage of 64,910 acre-ft against a normal storage of 0 acre-ft. Its maximum discharge capacity is 147,000 cubic feet per second.
