Inshore Reefs

Overview • 29 reef sites statewide • Enhancements over time to some sites • Inshore reefs created with shell, limestone, recycled concrete, and reefballs

Completed FY 17-18 • St John Reef in Lake Pontchartrain (4,000 tons) • Point Mast Enhancement in Lake Pelto (2,000 tons)

St. John Artificial Reef Deployment 10 acres ∙ 4,000 tons

St. John Artificial Reef Survey Plat

Point Mast Artificial Reef Enhancement 50 acres ∙ 2,000 tons • Original Reef deployed 2009 • Reef Site expanded to 50 acres in 2015 • 2017 Reef Material: Limestone

Upcoming Projects • Sweet Lake Reef (1-2,000 tons) • Contract drafted but not finalized • RFIQ advertisement closed – 7 reefs proposed • Multibeam Inshore compliance monitoring survey

Sweet Lake Artificial Reef Enhancement 50 acres Previous deployment 9,671 tons - 2012 Planned deployment area - 2018

Inshore Multibeam Compliance Monitoring Survey Contract • Vendor has been chosen • Compliance monitoring looking for: • Moving • Subsidence • Bottom types within permit area • Much higher resolution than 2013 side scan • Outreach materials
