Abstract
An auger dredge for removing toxic sediments wherein turbidity is minimized by attaching to the dredge a frame which first dislodges the material and feeds it to the auger for eventual transfer to a disposal site. Because the auger does not touch the dredged material directly turbidity which would otherwise be stirred up by the auger is vastly reduced.
