Rose City Yacht Club, a long-standing private marina and social club along the Columbia River in Portland, Oregon, recently took delivery and startup of a new 8-inch Badger Class dredge from Reserve, Louisiana-based DSC Dredge, LLC. The Badger dredge was a much-needed replacement for an older dredge the club had purchased used and had operated for more than 20 years. After extensive research into its options, the yacht club’s members decided in early 2015 to order the Badger Class dredge, which is manufactured at DSC’s Greenbush, Michigan, facility.

J.E. Borries Inc. is a 22-year-old, family-owned, full-service marine construction and dredging company based on the Mississippi Gulf Coast. The company was awarded a project by the Mississippi Department of Marine Resources to complete the dredging of three bayous in and around Gulfport, Mississippi, in an ongoing reconstruction effort following Hurricane Isaac in 2012, which caused siltation along that section of the Mississippi coast. J.E. Borries had previously completed all of its dredging work by mechanical means, using a long-reach excavator or a clamshell friction crane.
