About this gauge's record
USACE's continuous elevation record for this project begins in 1968 .
The dam behind Emmett Sanders Lock & Dam
Emmett Sanders Lock & Dam is held back by Emmett Sanders Lock and Dam (also recorded as Pool 4; Lock & Dam 4) , a concrete structure , standing 46 ft high and running 18,400 ft along its crest , built across ARKANSAS in Jefferson County , near GILLETT . It was completed in 1968 , and is owned by USACE - Little Rock District (a federal owner) , to a design credited to CESWL.
Its recorded primary purpose is navigation — the pool is held inside a narrow band to keep a navigable depth, so large swings are rare by design . It also serves navigation;recreation.
It is founded on soil, with a concrete core. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. The spillway opening is 1,020 ft wide.
NID classes it significant hazard potential: a failure would be expected to damage property and infrastructure rather than cost lives. It is a consequence rating, not a condition rating.
At its normal pool the reservoir covers about 5,680 acres. NID records a maximum storage of 77,000 acre-ft against a normal storage of 70,400 acre-ft. Its maximum discharge capacity is 375,000 cubic feet per second.
