Dredging in Ocean Outlets

January 3, 2013

Question: I know suction dredging is not allowed in most streams and rivers without a permit, but what about the ocean inlets or outlets for streams and rivers? Would it be ok to dredge these points without going into them? (Anonymous)

Answer: DFW’s authority for suction dredging is limited to rivers, streams and lakes and does not extend to the ocean (see Fish and Game Code, section 5653). Our authority for regulating suction dredges does not extend seaward from the mouth of a river or stream.

However, permits may be required by the state Coastal Commission, U.S. Army Corps of Engineers or local agencies (e.g. a harbor district). We recommend anyone proposing to suction dredge in the marine environment contact those organizations directly to determine what requirements apply.
