About this gauge's record
This site's drainage basin covers approximately 136 sq mi of contributing watershed. USACE's continuous storage record for this project begins in 2016 (2 tracked series for this project).
The dam behind Addicks Reservoir
Addicks Reservoir is held back by Addicks Dam , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 49 ft high and running 61,166 ft along its crest , built across SOUTH MAYDE CREEK in Harris County , near HOUSTON . It was completed in 1948 , and is owned by USACE - Galveston District (a federal owner) , to a design credited to CESWG.
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.
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 18,530 ft wide. Its outlet works use slide (sluice gate)0.
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 199,643 acre-ft against a normal storage of 0 acre-ft. Its maximum discharge capacity is 7,850 cubic feet per second.
