Volunteer

Lake Pontchartrain Basin Foundation's success depends on the dedication and talents of thousands of volunteers. People often volunteer with us because they feel a personal commitment to protecting and restoring our basin, so that all of us can enjoy it. Motivated by this valuable feeling of ownership, volunteers get involved in a variety of fun, interesting events that we hold throughout the year. Learn more

Many of these events are annual, including our Back to the Beach Festival, Beach Sweep, Fishing Rodeo, Golf Classic, and Northshore "Let's Make Waves" Party.

Lake Pontchartrain Basin Foundation staff also welcomes those who wish to volunteer in our office. Office volunteers regularly offer their time and talents throughout the year. Their assistance is invaluable. Learn more

Our Basin

History of the Pontchartrain Basin

Lake Pontchartrain began forming about 5,000 years ago when North American glacier melts caused the Mississippi River to swell and shift to the east. The river began depositing its sediments into the Gulf of Mexico, creating a broad delta which would later become Orleans, St. Bernard, and Plaquemines Parishes.

The delta grew slowly eastward over 2,000 years and eventually separated a large body of water from the Gulf. Native Americans called this body of water 'Okwata' meaning 'wide water', and they dwelled peacefully on its shores for centuries.

In 1699, Native Americans led the French settler, Pierre La Moyne, Sieur d'Iberville, on a journey through the area's Lakes and bayous. Iberville marveled at Okwata and renamed it Lake Pontchartrain, after the French Minister of the Marine at the time, the Comte de Pontchartrain.

Lake Pontchartrain is just one part of a vast ecological system called the Pontchartrain Basin. Known for its slow flowing rivers and bayous, tranquil swamps, and lush hardwood forests, the Basin provides essential habitat for countless species of fish, birds, mammals, reptiles, and plants.

The famous wetlands and marshes that surround the Basin's waters provide a beautiful setting for wildlife and are the heart of the region's commercial and recreational fisheries.

The Pontchartrain Basin is also the center of southeastern Louisiana's unique cultural heritage. With almost 2.1 million residents, including rural farming communities, metropolitan New Orleans, and the fishing, shrimping, crabbing, and oyster industries, the area is brimming with a diversity of people bound by a common interest: the desire for clean and healthy waters in the Pontchartrain Basin.

Our Basin comprises over 10,000 square miles of land in 16 Louisiana parishes and 4 Mississippi counties. All of these lands drain into rivers and bayous, which empty into Lake Pontchartrain and its connecting sister Lakes, Maurepas and Borgne.

The Pontchartrain Basin is bounded to the north by the Louisiana-Mississippi border, to the west by Thompson Creek and the Mississippi River, by the Breton and Chandeleur Sounds and Chandeleur Islands to the south, and to the east by the Pearl River. The Basin is made up of the following parishes: Ascension, East Baton Rouge, East Feliciana, Iberville, Jefferson, Livingston, Orleans, Plaquemines, St. Bernard, St. Charles, St. Helena, St. James, St. John the Baptist, St. Tammany, Tangipahoa, and Washington. The Lake also exchanges water with the Gulf of Mexico through the Rigolets and Chef Mentuer Passes. This connection to the salt waters of the Gulf makes the Lake an estuarine system - one of the largest in the nation.

 

TIMELINE
Geologic History
200 mya- South America, Africa, and North America, part of Pangean supercontinent, pulled apart creating a basin that has evolved into the present day Gulf of Mexico.
180 mya A precursor to the Mississippi River began depositing sediment in the north central Gulf of Mexico.
146-92 mya Louisiana and a large portion of North America were covered by a huge inland sea.
20,000 years ago sea level was 360 feet lower and many small rivers were discharging sediment at the outer edge of the continental shelf.
4,000 years ago sea level rose and the Pine Island barrier system developed extending from Hancock County, Mississippi to New Orleans.
3,000 years ago the St. Bernard delta of the Mississippi River built out of the alluvial valley onto the continental shelf creating what is now the south shore of Lake Pontchartrain.
2,000 years ago, the Mississippi River diverted to the Lafourche delta. The natural transgression of the St. Bernard delta caused coastal land loss and the formation of the Chandeleur Islands.
1,000 years ago the Mississippi River diverted to the modern Birdfoot delta complex in the southern region of the Basin.
