Golden Triangle Marsh Creation

The Union Freshwater Diversion will convey fresh water from the Mississippi River into West Maurepas swamp, helping to prevent saltwater intrusion and encourage new vegetation growth.

The Manchac Landbridge Diversion directs freshwater flows and some sediment into degraded swamps and marshes adjacent to the Bonnet Carre Spillway to increase nutrient input,improve water quality, and foster vegetation growth.

This project consists of marsh restoration on an eroding, narrow land-bridge that separates Lake Pontchartrain from Lake Borgne and serves as a critical landscape feature that helps provide storm surge protection for more than 1.5 million people.

This project will help rebuild and sustain marsh and swamp in the Central Wetlands.

The East Maurepas Freshwater Diversions will benefit this large swamp complex by reconnecting it with the river, helping prevent further loss and the conversion to open water, as well as helping to temper rising salinities throughout the entire Pontchartrain Basin.
