The Caminada Back Barrier Marsh Restoration Project is located in an especially dynamic area of the Louisiana Coast. The landward shoreline migration of the beach will significantly impact the project area over the 20 year… More
The south shoreline of White Lake has been retreating at an estimated average rate of 15 feet per year as a result of wind-induced wave energy. If the shoreline would have continued eroding in the project area, low marsh management levees likely would have been breached, which would have increased interior marsh loss rates in the project area.
This project included constructing segmented breakwaters to protect approximately 61,500 linear feet of shoreline to protect 687 acres of shoreline and interior marsh over twenty years. The breakwaters were constructed with gaps to allow aquatic organisms and water to move freely. An estimated 270,000 tons of stone was placed on geotextile fabric. Material dredged to create a flotation channel was placed beneficially behind the breakwaters to create approximately 172 acres of marsh substrate.
The project is located along the southern shoreline of White Lake from Will’s Point to the western shore of Bear Lake in Vermilion Parish, Louisiana.
Project construction was successfully completed in August 2006.
This project is on Priority Project List (PPL) 12.

A trademark of the freshwater swamp landscapes in temperate climate zones, this deciduous conifer has made its mark as a signature resident of Louisiana, having been named the state tree. The widely adaptable bald cypress thrives best in wet, swampy soils of riverbanks and floodplains and is commonly thought of as a famous inhabitant of American swamplands, such as those that border the Mississippi River. Cypress trees will often have Spanish moss draped from branches and cypress knees protruding from the water or soil surface, as well as terrestrial and aquatic wildlife in close proximity who are dependent upon these trees. Swamp imagery usually includes bald cypress trees which are commonly correlated with Cajun culture. Cypress trees also contribute to a major portion of Louisiana’s forestry industry with an estimated annual harvest of 30 million board feet per year. The town of Patterson was once home to the largest cypress sawmill in the world and is now designated as the Cypress Capitol of Louisiana. Having both historical and economic importance, cypress trees that are at least two hundred years old and alive at the time of the Louisiana Purchase are being identified and landmarked as part of the Louisiana Purchase Cypress Legacy program to commemorate the state’s natural heritage. Cypress trees have been considered essential in the representation of swamp wetlands and hold exceptional importance to Louisiana.
The Louisiana Sea Grant College Program hosted its annual educational, coastal-based event, Ocean Commotion, on October 27 at the LSU Pete Maravich Assembly Center in Baton Rouge, La. The primary purpose of Ocean Commotion is to give students the chance to learn about and touch the products of the sea and coast—the aquatic animals, plants, and minerals—upon which Louisiana’s citizens are so dependent. In attendance were 2,138 K-8 students, 121 teachers and 139 chaperons from East Baton Rouge, Iberville, Jefferson, East Feliciana, and Assumption parishes.
The Coastal Wetlands Planning, Protection, and Restoration Act encourages the connection between students and the coast by providing the opportunity to become “hands-on” with activities that foster interests in and curiosity for Louisiana’s passive shoreline environments. Among the 70 exhibits from universities, non-profits, state and local governments, student clubs, science and museum centers and K-12 student exhibitors was the CWPPRA Mysterious Wetland Wonders activity. Participants were encouraged to reach inside the seven mystery boxes, read clues, and try to identify the wetland item hidden inside each box without peeking! The mystery items included a seashell, apple snail shell, oyster shell, cypress knee, Spanish moss, nutria pelt, and a magnolia seed pod. In order for future generations to effectively protect our oceans, coastlines, and wetlands, learning about the importance and benefits of each is essential.
The Louisiana Association of Teachers of Mathematics (LATM) and the Louisiana Science Teachers Association (LSTA) held its 2016 Joint Conference: Cultivating STEM for the Future on October 24-26 at the Baton Rouge River Center. The LATM/LSTA joint conference’s focal point was the integration of math and science in the classroom. The conference provided an opportunity for educators of math and science to gain knowledge, tools, and strategies through interactive extended sessions, field experiences, and concurrent sessions. Over the duration of the three-day conference, exhibitors showcased educational materials and instructional equipment in order to further aid the teachers in math and science literacy. The CWPPRA Public Outreach staff shared educational materials and publications applicable to environmental science teachers and others seeking knowledge about Louisiana’s coastline.
For 25 years, the Coastal Wetlands Planning, Protection, and Restoration Act has provided the only joint Federal/State coastal restoration effort with a predictable and recurring funding stream designed to restore the vanishing wetlands of coastal Louisiana. The CWPPRA program continues to pursue a full slate of coastal restoration activities, and its progress and experience provide the foundation for restoration supported by one-time funding from various other sources. CWPPRA represents a collaborative effort and is managed by a Task Force comprised of five federal agencies and the State of Louisiana. CWPPRA’s Managing Agencies include:
The Louisiana Coastal Protection and Restoration Authority is the local cost-share partner that matches 15% of CWPPRA’s federal funding.
The Teche-Vermilion Basin Project was included in the 1966 Flood Control Act after a 1961 study by Louisiana’s Department of Public Works showed deteriorating water quality and insufficient water in Bayou Vermilion and Bayou Teche. Ground water was threatened with contamination by salt water due to lack of flow of the Teche and Vermilion Bayous. The purpose of the project is to restore the flow of water to the Teche-Vermilion basin, improve water quality through the increased flow, and prevent salt water from entering the lower parts of the basin. The increased flow is also intended to restore the water supply available for agricultural and industrial needs before the protection levees were built. The state legislature created the Teche-Vermilion Freshwater District Board of Commissioners in 1969. The Board of Commissions was charged with responsibility for the maintenance and operations of the original project of the Army Corps of Engineers, as well as major replacements.
On October 21, CWPPRA staff attended the Teche-Vermilion Fresh Water District Annual Inspection Meeting at the Teche-Vermilion Pump Station in Krotz Springs, La. The meeting began with a welcome speech from Donald Sagrera, TVFWD Executive Director. Introductions of property possession parish commissioners were made beginning with Ed Sonnier, Lafayette Parish; Donald Segura, Iberia Parish; Tommy Thibodeaux, St. Martin Parish; Mike Detraz, Vermilion Parish; and Bradley Grimmett, St. Landry Parish. A positive inspections report was given by Darrel Pontiff of Louisiana Coastal Protection and Restoration Authority, as well as Ted Elts of U.S. Army Corps of Engineers. Ed Sonnier, TVFWD Chairman, introduced Lafayette Mayor-President Joel Robideaux, who was the event’s guest speaker. The presentation continued with recognition of TVFWD staff and sponsors given by Cecil Knott, Operations Supervisor, and Alex Lopresto, TVFWD Legal Advisor. TVFWD Executive Director Donald Sagrera ended the ceremony with closing remarks.
The project area is located in the Cameron-Creole Watershed Management Area which protects approximately 64,000 acres in the watershed. It includes a 16.5 mile levee along Calcasieu Lake and five large concrete water control structures to manage the unit and prevent the effects of saltwater intrusion, by managing salinity, tidal exchange, water levels, and estuarine organism movement into and out of the watershed. The Calcasieu Ship Channel, immediately west of the project area, provides an avenue for the rapid movement of high-salinity water into the marshes around Calcasieu Lake. This movement increased salinity in the area, resulting in plant death and marsh loss. The weakened marshes located between the East Fork of the Calcasieu River and Calcasieu Lake has also been decimated by hurricanes. Marshes that once provided a buffer to the southwest rim of Calcasieu Lake are now shallow open water areas.
The proposed project’s primary feature is to create and/or nourish approximately 533 acres of saline marsh (502 acres created, 21 acres nourished and 10 acres of creeks/ponds) south of Calcasieu Lake. In order to achieve this, approximately 3.5 million cubic yards of sediment will be hydraulically pumped from the upland disposal areas of the Calcasieu River immediately adjacent to (across East Fork), and into the shallow water marsh creation area to an elevation of 1.4 ft NAVD 88. Clean out approximately 5,000 LF of the Cameron Creole Watershed Levee borrow channel to facilitate water movement into the newly created area. Containment dikes will be constructed around the marsh creation area to keep material on site during pumping. Once pumping has been completed, the containment dikes will be degraded to the current platform elevation and gaps will be excavated. Additionally, 251 acres of vegetative plantings will occur within the newly created areas. Approximately 10,000 linear feet of tidal creeks and two 2.5 acre ponds will be constructed to help facilitate hydrologic flow of water in and out of project area.
