Crews began dredging Knapps Narrows near Tilghman Island this past weekend as part of maintenance dredging being overseen by the U.S. Army
Corps of Engineers, Baltimore District to ensure continued safe navigation
along the federal channel.
The Knapps Narrows Federal Navigation Channel is important to the
local economy and is used heavily by watermen and for recreational purposes. It
is also the main access to Poplar Island.
The dredging is being done through
a $1.4 million contract awarded by the U.S. Army Corps of Engineers to
Southwind Construction of Evansville, Indiana earlier this year.
As part of the maintenance
dredging, crews will be removing roughly 100,000 cubic yards of material from
the Knapps Narrows Federal Navigation Channel to restore it to its authorized
depth of 9 feet (MLLW), plus two feet of allowable overdepth, and a width of 75
The U.S. Army Corps of Engineers
has coordinated closely with the Maryland Department of Environment and Talbot
County on the project and dredge material placement site. The material,
consisting of clay, mud, sand, silt and shell and combinations thereof, will be
placed via pipeline at the previously used upland site located on approximately
20 acres of the Donnel-Jones Farm. Work to prepare the placement site to accept
material was previously completed via a separate contract.
Dredging work in the channels is
expected to be done in May, ahead of Memorial Day weekend.
