	Geologic Framework and Processes of the Lake Pontchartrain Basin - U.S. Geological Survey
		Lake Pontchartrain and adjacent lakes in Louisiana form one of the larger estuaries in the Gulf Coast region.
		This change is evident in the bottom sediments, which record the historic health of the lake.
		Also, land-altering activities such as logging, dredging, and flood control in and around the lake, lead to shoreline erosion and loss of wetlands.The effects of pollution, shoreline erosion and wetland loss on the lake and surrounding areas have become a major public concern.

	Lake Pontchartrain - Wikipedia, the free encyclopedia
		Pontchartrain is an estuary which connects with the Gulf of Mexico via Rigolets strait (known locally as "the Rigolets") and Chef Menteur Pass into Lake Borgne, and experiences small tidal changes.
		Lake Maurepas connects with Lake Pontchartrain on the west via Pass Manchac.
		Lake Pontchartrain Causeway was constructed in the 1950s and 1960s, connecting New Orleans (by way of Metairie) with Mandeville and bisecting the lake in a north-northeast line.

		The Lake Pontchartrain Causeway is the longest highway bridge over water in the entire world, spanning 23.9 miles from Metairie on the South Shore to St. Tammany Parish on the North Shore.
		Although the Causeway Commission previously maintained offices and toll booths on each side of the Lake Pontchartrain, on May 5, 1999 the Metairie south shore booths were taken out of service and the $1.50 toll was eliminated to reduce traffic congestion on the south shore's Causeway Boulevard.
		Lake Pontchartrain is the largest inland estuary in the United States.

	Lake Pontchartrain Basin (Site not responding. Last check: 2007-11-05)
		Lakes Maurepas and Pontchartrain are separated by land bridges of cypress swamp and fresh/intermediate marsh.
		The basin contains 483,390 acres of wetlands, consisting of nearly 38,500 acres of fresh marsh, 28,600 acres of intermediate marsh, 116,800 acres of brackish marsh, 83,900 acres of saline marsh, and 215,600 acres of cypress swamp.
		The primary causes of wetland loss in the basin are the interrelated effects of human activities and the estuarine processes that began to predominate many hundreds of years ago, as the delta was abandoned.

	Maintaining Southern's Lake Pontchartrain Bridge
		Pontchartrain is the largest lake in Louisiana and the largest salt water lake in the world, with an area of some 630 square miles.
		When the bridge was first built, the approaches spanned some 12 miles of swampy ground on the south side of the lake and an additional three miles on the north end.
		Although working out in the middle of Lake Pontchartrain does, as one member of the bridge crew remarked, "get a little 'hairy' at times" there are compensations.

	About Us
		The Lake Pontchartrain Basin Foundation is a non-profit organization consisting of a 14-member board of directors representing the Basin parishes and regulatory agencies.
		The Lake Pontchartrain Basin Foundation was established in response to environmental concerns voiced throughout the Basin.
		In the spring of 1989, a report called "To Restore Lake Pontchartrain", written by professors at Tulane University and the University of New Orleans, called for the establishment of an entity whose sole focus would be a healthy Lake and Basin.

	Erosion Control \| Taming Shoreline Erosion
		An important factor in the destruction of valuable wetlands along Pontchartrain’s shores, according to Shea Penland, a professor of geology at the University of New Orleans, is the manner in which many owners of lakefront property have dealt with shoreline erosion, which ranges from 3 to 25 ft./yr.
		His proposal is to create new wetlands at various stretches along the Lake Pontchartrain coast, areas of submerged vegetation, and new beaches and sand dunes, all of which would act as natural barriers against erosion while re-creating natural habitats.
		The concept was that the Lake Salvador waters impinging on the wave break would be slowed and–after penetrating the porous, Christmas tree—filled crib–would then continue into the quiescent region between crib and shoreline, where they would drop their sediment load and help to create a new marshland.

		Lake Pontchartrain, the large water mass north of New Orleans, is the focus of many of these fears.
		Yet the lake is the city's traditional drain, and it is impractical to try to pump all the water out to the south.
		Pontchartrain's ecosystem may have been hit directly by Katrina at the very beginning, when surges of seawater from the Gulf of Mexico arrived, dangerously increasing its salt content.

		Builders of the New Basin Canal, which connected the downtown American sector of New Orleans with Lake Pontchartrain, preferred to hire Irishmen because the work was dangerous, and they did not want their valuable slaves injured or killed.
		In modern times the first drive towards its navigational advantages and eventually its refreshment and recreation was punctuated in the 1830's by the Pontchartrain Railway to the resort village of Milneburg (along the present Elysian Fields to camps and resorts Avenue), and the New Basin Canal with its accompanying shell road (replaced by Pontchartrain Expressway).
		Financially, the canal was a success as it opened up trade with communities north of Lake Pontchartrain and the cities of Biloxi, Mobile, and Pensacola on the Gulf of Mexico.

		Perceptions are widespread and common among the general public that Lake Pontchartrain Basin is both a source and a sink for contaminated sediments.
		Muddy sediments are stabilized by sea grasses growing on parts of the lake floor, but muddy sediments in bare areas of the shallow Basin are frequently resuspended by waves, currents, and flooding.
