The dam behind Lake Alan Henry Reservoir
Lake Alan Henry Reservoir is held back by John T Montford Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 141 ft high and running 4,150 ft along its crest , built across DOUBLE MOUNTAIN FORK BRAZOS R in Garza County . It was completed in 1994 and modified in 2012O , and is owned by CITY OF LUBBOCK (a local government owner) , to a design credited to CITY OF LUBBOCK;FREESE AND NICHOLS.
Its recorded primary purpose is irrigation — the pool is drawn down across the growing season to serve water rights downstream, then refilled over winter . It also serves irrigation;recreation;water supply.
It is founded on soil, 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 1,740 ft wide. Its outlet works use other controlled7;uncontrolled2.
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. Its most recent condition assessment was satisfactory — no deficiencies recognised for expected loading. That assessment is dated 06/17/2024.
At its normal pool the reservoir covers about 2,884 acres. NID records a maximum storage of 354,500 acre-ft against a normal storage of 115,937 acre-ft. Its maximum discharge capacity is 363,480 cubic feet per second. It is regulated by TCEQ.
