The lower salinity marshes are converting to shallow, open water due to elevated salinity events and subsidence. Navigation channels provide a direct route for salt water to infiltrate the marsh, disrupt the natural water circulation, and allow rapid runoff of fresh water. The larger Sabine-Neches Waterway and the Gulf Intracoastal Waterway (GIWW) have allowed saltwater intrusion into the project area’s fresh and intermediate marshes. Elevated tidal fluctuations in these channels have led to increased water flow, which has increased the conversion of marsh to open water. Area marsh loss is also caused by wave action along Sabine Lake and interior marsh shorelines and other natural causes (i.e., subsidence).
The project features include: a rock weir in Pines Ridge Bayou; three culverts with flap gates at Bridge Bayou; a 3,000 foot-long rock rip-rap breakwater along the Sabine Lake shoreline at Willow Bayou; a weir/plug at the opening at Starks South Canal Section 16 levee; and 232,000 linear feet of vegetated earthen terraces in the vicinity of Greens Lake.
The project is located in the western portion of the Sabine National Wildlife Refuge from Pool 3 to the eastern shoreline of Sabine Lake in Cameron Parish, Louisiana.
Construction was completed in October 2010.
This project is on Priority Project List 10.

On Saturday, October 13th, the CWPPRA outreach team rolled up to the Southeast Louisiana National Wildlife Refuges Headquarters in Lacombe, LA for Wild Things. The U.S. Fish and Wildlife Service puts on Wild Things every year during National Wildlife Refuge Week to celebrate wildlife and getting out into nature. This year we brought our Wetland Wonders game, along with all our regular publications. We underestimated how popular our materials would be and quickly ran out of everything. We were set up on a beautiful day in the shade. Nearby, families could learn about wilderness survival, injured bird rehabilitation, native animal and plant species, and much more.
The Wetland Wonders game was well-received by children and adults alike. We had a short lull around lunchtime but otherwise the boxes constantly had visitors. Our Wetland Wonders activity asks players to guess the object inside the box without looking at it. Players can feel inside and read clues that are on the front of the boxes. Many people start out timid from the mystery but play the game once they believe there is nothing alive or gross in the boxes. We enjoy events like this and we urge you to seek similar events for your family and friends. To find more events by the Fish and Wildlife Service, you can visit their website and search for your nearest Wildlife Refuge. Get out and #ProtectOurCoast!
Families enjoying a Saturday adventure together on March 11th had the chance to explore different aspects of the ecosystems around them, including ways that wetlands help them and native wildlife. Coastal Wetlands Planning, Protection, and Restoration staff exhibited materials and games at the Estuarine Habitats and Coastal Fisheries Center as part of 2017 Family Adventure Day to benefit the non-profit Healing House in Lafayette, LA. This annual event sends families to different locations throughout Lafayette for experiences that range from face painting to coming face-to- face with a snake.
Over 250 people stopped by the Center where they had the opportunity to see a demonstration of how coastal wetlands protect interior communities and wildlife habitat from storm surge. Visitors could pick up recent issues of WaterMarks and other materials on wetlands restoration projects in coastal Louisiana. Kids also received Henri Heron’s activity book and helped match Louisiana wildlife with the wetland habitat they need to survive.
Other exhibitors, including US Fish & Wildlife Service and Louisiana Dept. of Wildlife & Fisheries, focused on topics like bat conservation, beekeeping, endangered species in Louisiana, and fishing. Helping families understand and appreciate the diversity of natural environments in Louisiana helps ensure that those environments will be present in the future.
