In some [[police]] departments a small dredge (sometimes called a ''drag'') is used to find and recover objects and bodies from underwater. The bodies may be [[murder]] victims, or people who committed [[suicide]] by [[drowning]], or victims of accidents. It is sometimes pulled by men walking on the bank.
