About this gauge's record
This site's drainage basin covers approximately 490 sq mi of contributing watershed.
The dam behind Lake Fork Reservoir
Lake Fork Reservoir is held back by Lake Fork Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 85 ft high and running 12,660 ft along its crest , built across LAKE FORK CREEK in Wood County . It was completed in 1980 and modified in 2014O;2017S , and is owned by SABINE RIVER AUTHORITY OF TEXAS (a state owner) , to a design credited to FREESE & NICHOLS, INC;FREESE & NICHOLS, INC.;USR FORREST & COTTON INC.
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;recreation.
It is founded on soil, with a earth core. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. The spillway opening is 200 ft wide. Its outlet works use other controlled1;slide (sluice gate)4.
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 04/27/2015.
At its normal pool the reservoir covers about 27,690 acres. NID records a maximum storage of 1,269,599 acre-ft against a normal storage of 675,819 acre-ft. Its maximum discharge capacity is 127,736 cubic feet per second. It is regulated by TCEQ.
