Federally authorized channel dimensions on the Crossings are 500 feet wide by 45 feet deep, the Corps continues to focus on the central 250 feet of channel or half of the authorized channel width. The Corps of Engineers Mississippi Valley New Orleans (MVN) has resumed dredging operations in Southwest Pass (SWP) and on the Crossings Above New Orleans to respond to active shoaling deposited by long-term high river stages (historic flood event and precipitation levels). There are three hopper dredges presently working in the area of SWP (2 industry hoppers and 1 government hopper) and two dustpan dredges working to restore half channel width on the Crossings.
