Calcasieu River

WMI’s Dredging Division was tasked with excavating 19 miles of maintenance material from the Calcasieu River. The hydraulic dredge G.D. Morgan pumped 8.8mcy of material and created approximately 650 acres of new marsh. Weeks also pumped some material into upland sites.

A challenging aspect of the project was laying pipeline from the Calcasieu River to the Black Lake Marsh creation site, which was 55,000’ from the dredge area and scattered with numerous docks, pipelines, and oilfield locations along the route to the disposal area.
