About this gauge's record

This site's drainage basin covers approximately 123 sq mi of contributing watershed. USACE's continuous elevation record for this project begins in 2015 .

The dam behind Lost Creek Reservoir

Lost Creek Reservoir is held back by Lost Creek Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 99 ft high and running 2,250 ft along its crest , built across LOST CREEK in Jack County . It was completed in 1991 and modified in 1994S;2005S , and is owned by CITY OF JACKSBORO (a local government owner) , to a design credited to HDR;UNKNOWN;UNKNOWN.

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 is founded on unlisted/unknown, 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 1,205 ft wide. Its outlet works use uncontrolled2;valve1.

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 02/02/2022.

At its normal pool the reservoir covers about 390 acres. NID records a maximum storage of 21,831 acre-ft against a normal storage of 11,900 acre-ft. Its maximum discharge capacity is 2 cubic feet per second. It is regulated by TCEQ.
