About this gauge's record
USACE's continuous elevation record for this project begins in 1969 .
The dam behind Lock & Dam 08
Lock & Dam 08 is held back by Toad Suck Ferry Lock and Dam (also recorded as Pool 8) , a concrete structure , standing 58 ft high and running 1,450 ft along its crest , built across ARKANSAS in Faulkner County , near LITTLE ROCK . It was completed in 1969 , 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 rock, 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 1,120 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 4,130 acres. NID records a maximum storage of 37,300 acre-ft against a normal storage of 33,000 acre-ft. Its maximum discharge capacity is 368,000 cubic feet per second.
