On August 3, 2017, the Senate unanimously approved a resolution designating the week of September 16th through September 23rd as National Estuaries Week.
Over 100 million people nationwide live near estuaries and use these resources in their daily lives through agriculture, tourism, commercial fishing, power generation, and as shipping ports. Estuaries, where the river mouths meet the ocean, are where fresh and saltwater mix. One of the most expansive and productive estuaries in the world is located in the United States at the interface of the Mississippi River and the Gulf of Mexico. Along with providing jobs, estuaries have one of the highest productivity rates among ecosystems in the world. Estuaries serve as habitat for fish, waterfowl, and a variety of other wildlife by providing food and shelter during migration and mating season.
Estuaries are a well-known hotspot for recreational fishing. Take part in celebrating National Estuaries Week by reeling in a big catch while helping to keep your estuary areas clean of trash and healthy for the wildlife and vegetation. Visit our friends over at the Barataria-Terrebonne National Estuary Program for a list of activities and ways you can participate in National Estuaries Week.
Approximately 14,390 acres (32%) of the Cameron-Creole
Watershed Project (CCWP) marshes were lost to open water
from 1932 to 1990 at an average loss rate of 248 acres/year
(0.55 percent/year) due to subsidence and saltwater intrusion
from the Calcasieu Ship Channel. The
CCWP was implemented by the NRCS in 1989 to reduce
saltwater intrusion and stimulate restoration through
revegetation. Hurricanes Rita and Ike in 2005 and 2008
breached the watershed levee scouring the marsh and
allowing higher Calcasieu Lake salinities to enter the
watershed causing more land loss. The Calcasieu-Sabine
Basin lost 28 square miles (17,920 acres) (4.4%) as a result
of Hurricane Rita (Barras et al. 2006). Land loss is estimated
to be 1.33 percent/year based on USGS data from 1985 to
2009 within the extended project boundary.
Project goals include restoring and nourishing hurricane-scoured
marsh in the Cameron Prairie National Wildlife
Refuge and adjacent brackish marshes of the Calcasieu Lake
estuary. Approximately 3 million cubic yards of material
would be dredged from a borrow site proposed in Calcasieu
Lake and placed into two marsh creation areas north of
Grand Bayou to restore 609 acres and nourish approximately
7 acres of brackish marsh. The borrow site would be
designed to avoid and minimize impacts to oysters and other
sensitive aquatic habitat. Tidal creeks would be constructed
prior to placement of dredge material and retention levees
would be gapped to support estuarine fisheries access and
to achieve a functional marsh. The project would result in
approximately 534 net acres of brackish marsh over the 20-
year project life.
This project is located in Region 4, Calcasieu-Sabine Basin,
Cameron Parish, 6 miles northeast from Cameron, LA, on
the Cameron Prairie NWR and Miami Corporation property
north of Grand Bayou.
This project is on Project Priority List(PPL) 20.

For centuries, Louisiana has had a prospering commercial seafood industry. The catching and selling of shrimp, crabs, oysters, alligator, fish, and crawfish have sustained the livelihood of many families. As one of the country’s largest seafood suppliers, Louisiana contributes more than 850 million total pounds of high-quality seafood to restaurants and homes across the world each year.
Louisiana’s fisheries are an integral part of our economy through providing jobs, as well as income and tax revenue. One of every seventy jobs in Louisiana is related to the seafood industry. As a whole, this leaves an economic impact of over $2.4 billion annually for the state of Louisiana. For many of the industrious fishermen who work Louisiana’s waters, their craft of bringing the finest seafood to the plates of people around the world has been passed down for many generations.
What makes Louisiana waters so plentiful? The abundance of seafood caught and served around the world all starts with our estuaries. An estuary is an ecosystem commonly located where a river meets the sea. Estuaries are inhabited by an array of plant and animal species that have adapted to a mixture of fresh and salt water caused by tidal flow. This changing mixture makes estuaries a fertile region for a variety of marine life. Along with estuaries providing an abundance of seafood, they also provide access to recreational activities and breeding and migratory locations and shelter for fish and wildlife.
Did You Know?
75% of the United States commercial sea catch comes from estuaries.
37% of estuary marshes in the United States are in Louisiana.
Louisiana is the largest commercial fishery in the United States.
Louisiana estuaries comprise the seventh largest estuary in the world.
You can help maintain healthy estuaries by keeping your estuary area clean of trash and robust for our seafood industries, wildlife, vegetation, and others to enjoy! Louisiana’s seafood industry promotes innovations that protect our coastline and help keep our waters clean. When you select Louisiana seafood, you are supporting the lifestyle and environment Louisiana natives have depended on for centuries. As they say about Louisiana seafood, “know better, eat better.”
An estuary is an ecosystem comprised of both the biological and physical environment, commonly located where a river meets the sea. Estuaries are inhabited by an array of plant and animal species that have adapted to brackish water—a mixture between freshwater draining from inland and salt water. One of the most expansive and productive estuaries in the world is located in the United States at the interface of the Mississippi River’s freshwater and the salt water from the Gulf of Mexico.
Estuaries have one of the highest productivity rates among ecosystems in the world; they provide an abundance of food and shelter as well as breeding and migration locations. Estuaries also provide great access for enjoyable recreational activities such as fishing. Continue your love for estuaries and contribute to their well-being by aiming to keep your estuary areas clean of trash and healthy environments for wildlife, vegetation, and others to enjoy!

There are four different types of wetland marshes in Louisiana.
Due to Louisiana’s proximity to the Gulf of Mexico, the exchange between fresh and salt water along the coast is frequent. Depending on the location of the marsh, it could be classified as either freshwater, intermediate, brackish, or saltwater marsh. Marshes are categorized by the salinity, or salt content, of the water, and the location of marshes to the Gulf of Mexico often directly correlates with the salinity level. Generally following a salinity gradient, freshwater marshes are commonly situated furthest inland from the gulf with a salt content of 0 ppt (parts per thousand), intermediate marshes contain a salinity range of 0-5 ppt, brackish marshes have a range of 5-15 ppt, and saltwater marshes encompass a salt content of 15 ppt or greater. Within the marsh gradient are estuaries, where fresh and salt water mix and many wetland species spend their juvenile lives.
