About this gauge's record

This site's drainage basin covers approximately 634 sq mi of contributing watershed.

The dam behind Medina Lake

Medina Lake is held back by Medina Lake Dam , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 165 ft high and running 1,540 ft along its crest , built across MEDINA RIVER in Medina County , near RIOMEDINA . It was completed in 1913 and modified in 2012S , and is owned by BEXAR MEDINA ATASCOSA COUNTIES WCID 1 (a local government owner) , to a design credited to BARTLETT AND RANNEY;URS.

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 is founded on soil, with a unlisted/unknown;unlisted/unknown 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 880 ft wide. Its outlet works use uncontrolled1;vertical lift5.

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 10/24/2025.

At its normal pool the reservoir covers about 5,625 acres. NID records a maximum storage of 324,719 acre-ft against a normal storage of 251,756 acre-ft. Its maximum discharge capacity is 491,024 cubic feet per second. It is regulated by TCEQ.
