The Mississippi Department of Marine Resources urges boaters to be cautious around a project to expand Katrina Key reef on the south side of Deer Island.
Concrete rubble will be deployed by barge to expand the existing Katrina Key structure to the west beginning Friday.
Work is expected to last two to three weeks depending on weather conditions. The MDMR requests that boaters allow a 200-foot buffer zone around the barge and spotter boat while construction is under way. Permanent aids to navigation will be installed work is completed.
