A dredge is a small waterborne craft used to remove sediment from the bottoms of rivers and harbors. Dredges are mainly used for landscape control of manmade harbors as well as trash and debris control. In some police departments dredges are used for underwater location of murder victims or those who have committed suicide by drowning.
A dredge is also a large machine used to remove overburden in an open pit or strip mine, or, in the case of gold placer mining, to pick up ore and gravel and send it through sluices to remove gold and deposit the remaining rock, or tailings, behind the dredge.
