The U.S. Army Corps of Engineers (USACE) continues Fiscal Year 2024 (FY 24) channel maintenance dredging with the two industry hopper dredges: GLENN EDWARDS (Manson Construction) and PADRE ISLAND (Great Lakes Dredge & Dock). The hopper dredges are working under the FY 24 early award hopper dredge contracts (Awarded in Fiscal Year 2023 for Work in FY 24). The USACE has options to deploy the hopper dredges on the Crossings and in SWP while monitoring rising river stages and updated channel surveys. The industry hopper dredges could also be released to work in other USACE Districts depending on channel conditions along the Mississippi River Ship Channel.
