A lead shot recovery device is disclosed for reclaiming lead shot from a slurry of material taken from lake bottoms. In one embodiment, the device includes a sluice box having an open bottom riffle bed through which can pass a net upward liquid flow. The cooperative action of the upflow and the riffles causes lead shot to fall through the riffle bed and into a collection pit from which the lead shot can be continuously removed. A method for recovering lead shot using the recovery device is also disclosed.
