About this gauge's record
This site's drainage basin covers approximately 221 sq mi of contributing watershed.
The dam behind Lake Graham
Lake Graham is held back by Graham Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 82 ft high and running 4,300 ft along its crest , built across SALT CREEK in Young County , near GRAHAM . It was completed in 1959 , and is owned by CITY OF GRAHAM (a local government owner) , to a design credited to FREESE AND NICHOLS.
Its recorded primary purpose is water supply — delivering water to its customers comes first, so drawdown here follows demand as much as it follows rainfall . It also serves water supply;other.
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 1,050 ft wide. Its outlet works use uncontrolled1;valve2.
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 08/29/2025.
At its normal pool the reservoir covers about 1,900 acres. NID records a maximum storage of 105,000 acre-ft against a normal storage of 39,000 acre-ft. Its maximum discharge capacity is 175,000 cubic feet per second. It is regulated by TCEQ.
