The U.S. Army Corps of Engineers (USACE) continues working to restore the deficient reaches of the Mississippi River Ship Channel (MRSC) in the area of Southwest Pass with two industry hopper dredges and one industry cutterhead dredge. The hopper dredges GLENN EDWARDS, NEWPORT and the cutterhead dredge CAPTAIN FRANK are working on assignments in the area of Southwest Pass. The dustpan dredges, JADWIN and WALLACE McGEORGE, are working on the Crossings Above New Orleans.

INDUSTRY HOPPER DREDGE(S) IN THE AREA OF SOUTHWEST PASS (SWP):
GLENN EDWARDS: The hopper dredge GLENN EDWARDS (Manson Construction) continues dredging in the Venice area (Mile 13.0 Above Head of Passes [AHP] to Mile 12.0 AHP). The GLENN EDWARDS began dredging in Southwest Pass on March 20, 2020 under Southwest Pass Hopper Dredge Rental Contract #13-2019. This contract has been extended and the hopper dredge is now expected to complete work on approximately July 20, 2020.

The STUYVESANT was under contract to work in SWP for approximately 30 days. However, the contract was modified (shortened) since the hopper dredge also had contractual obligations on other channels (over extended).
BAYPORT: The hopper dredge BAYPORT (Manson Construction) is expected to begin dredging in SWP by June 17, 2020. The BAYPORT will work in SWP for approximately 30 days to complete hours on Calcasieu River Hopper Dredge Rental Contract 19C0076.

CUTTERHEAD DREDGE(S) IN THE AREA OF SOUTHWEST PASS (SWP):
CAPTAIN FRANK: Weeks Marine’s cutterhead dredge CAPTAIN FRANK continues dredging at Mile 17.46 BHP on assignment on the eastern side of the channel from Mile 15.8 BHP to Mile 18.0 BHP. The cutterhead commenced dredging in Southwest Pass on January 24, 2020 under Southwest Pass Cutterhead Dredge Rental Contract #3-2019. The CAPTAIN FRANK will commence dredging in the New Orleans Harbor upon completion of this assignment.
CUTTERHEAD DREDGE(S) IN THE HOPPER DREDGE DISPOSAL AREA (HDDA):
Weeks Marine has utilized multiple cutterhead dredges on this project and all material removed from the HDDA has been beneficially placed in the Pass A’Loutre Wildlife Management Area (PALWMA). The cutterhead dredges have beneficially utilized approximately 13.1 million cubic yards (mcy) of material removed from the HDDA and restored roughly 1,040 acres. When this project is completed approximately 1,200 acres will have been restored in the PALWMA. A cutterhead dredge will resume work on the HDDA contract to remove the remaining 1.9 mcy of material once priority channel maintenance demands have been completed. The MVN also received supplemental funding for Fiscal Year 2020 (FY 2020) sufficient to issue another HDDA contract, the bid advertisement will be opened later this calendar year.
DUSTPAN DREDGE(S) ON THE CROSSINGS ABOVE NEW ORLEANS:
The MVN is dredging to restore or maintain the central 250 feet of the channel (authorized width is 500 feet) on the Crossings Above New Orleans with two dustpan dredges.
