This project will construct gaps in the existing dredged material banks of the Amite
River Diversion Canal to allow floodwaters to introduce additional nutrients and
sediment into western Maurepas Swamp. The exchange of flow would occur during flood
events on the river and from the runoff of localized rainfall events. Nutrients
and sediment would be provided to facilitate organic deposition in the swamp, improve
biological productivity, and prevent further swamp deterioration.
Prior studies and reports have documented degradation in the swamp adjacent to the
diversion canal and have further demonstrated a need for ecosystem restoration that
stimulated historical hydrologic conditions.
This project is designed to complement two other LCA projects: the Hope Canal Diversion
and Convent/Blind River Diversion, and one proposed Coastal Impact Assistance Program
project, Hydrologic Restoration in Swamps West of Lake Maurepas.
The area is situated along the Amite River Diversion Canal in Ascension and Livingston
parishes, in the vicinity of Head of Island, Louisiana.
