The dam behind Coleto Creek Reservoir
Coleto Creek Reservoir is held back by Coleto Creek Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 65 ft high and running 18,950 ft along its crest , built across COLETO CREEK in Victoria County , near RAISIN . It was completed in 1980 , and is owned by GUADALUPE-BLANCO RIVER AUTHORITY (a state owner) , to a design credited to USR FORREST & COTTON INC.
Its recorded primary purpose is other .
It is founded on soil, with a earth core. Its outlet works use other controlled1;slide (sluice gate)1;uncontrolled1.
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 fair: sound under normal loading, though a rare or extreme event could expose a deficiency. That assessment is dated 01/31/2025.
At its normal pool the reservoir covers about 3,100 acres. NID records a maximum storage of 132,536 acre-ft against a normal storage of 35,084 acre-ft. Its maximum discharge capacity is 152,240 cubic feet per second. It is regulated by TCEQ.
