PROJECT STATUS REPORT as of 18-Sep-2024
Grand-White Lake Landbridge Restoration
PROJECT LOCATION:
The project is located in Cameron Parish, LA in the southeastern portion of Grand Lake. The project is bordered by Grand Lake to the west, Round Lake to the north, Collicon Lake to the east and the old Gulf Intracoastal Waterway to the south.
PROJECT DESCRIPTION:
Collicon Lake (3,000 ac) is in imminent danger of breaching (i.e., within 400 ft) into the eastern portion of Grand Lake. Should this breach occur, the size of Grand Lake will increase by over 4,800 acres and the size of the land bridge will be reduced by 2 miles. Shoreline erosion would accelerate in the marsh between the former Collicon Lake and Alligator Lake and Lake le Bleu. Project features consist of the following: 1) Install 2.1 miles (12,000 feet) of hard shoreline stabilization, with fish-sediment access locations, at the SE shore of Grand Lake from a point approximately 1,000 feet north of the Old Intracoastal Waterway to a point even with the Round Lake northern shoreline (the hard shoreline protection will be rock foreshore dike); 2) restore approximately 17 acres of marsh along the Grand Lake shoreline with 12,000 x60 feet of spoil from access channel construction; 3) install two 9,240 ft-long rows of vegetated linear terraces along the NW shore of Collicon Lake [74 units 200 ft long x 10 ft wide at the top (82 ft wide at base)] with 50 ft gaps between terraces. The terraces and gaps will be constructed in two rows parallel to the shoreline. The first row will be located approximately 50 ft from the shoreline in about 2.5 ft of water or shallower; the second row will be approximately 100 ft lakeward of the first row in about 3.5 ft of water or less. The terrace tops will be vegetated with seashore paspalum (Paspalum vaginatum) planted in two rows of 4-inch containers planted on 5 ft centers. The terrace slide slopes will be vegetated with Bullwhip (Scirpus californicus) or Giant cutgrass in four offset rows of gallon containers on 10 ft centers. The entire terrace tops will be seeded with a mixture of Bermuda, Brown topped and Japanese Millet or similar combination. The southern shoreline of Round Lake will be planted with two rows of gallon containers of Bullwhip or Giant cutgrass if sufficient funding is available.
PROJECT STATUS: (Project Status Last Updated: 20-Aug-2024 )
The project was approved for a two-year, no-cost extension. The new expiration date is October 2026 and will allow time for a final maintenance event to occur.
FUND STATUS:
The current project estimate is $4,974,137 , which includes $3,536,831 for construction first costs, and $289,115 and $1,148,191 for 20 years of monitoring and operations and maintenance, respectively.
