Dredging below McAlpine Locks,showing cutterhead of dredge
Bill Holman
The
navigation channel
below McAlpine Locks accumulates
sediment
during high water periods and so must be dredged every year
The
cutter-suction dredge
(or dredger)
Bill Holman
(built in 1978 by Ellicott Dredges, LLC) is owned by Luhr Bros., which is contracted by the
U.S. Army Corps of Engineers
to perform the work
As the cutterhead rotates, its teeth churn up the riverbed sediment, which is then sucked up and piped to a deposit area
In this photo, the cutterhead has been raised out of the water so a crewman aboard the workboat
Buddy
can remove debris caught in the teeth
At lower left is one of the guy wires which are used to swing the cutterhead back and forth
At upper right is the downstream end of
Sand Island
