J.F. Brennan Company, Inc., based in LaCrosse, Wisconsin, recently completed the inaugural project for its newest, fully customized Barracuda Class dredge from DSC Dredge, LLC. The Quad Cities Generating Station, a two-unit nuclear power plant located on the Mississippi River near Cordova, Illinois, requires biennial dredging of siltation near the secured water intake area of the plant. The newly commissioned 12-inch by 12-inch swinging ladder cutterhead Barracuda Class “Victor Buhr” was ideal for this project, which began in late April and was completed in late May 2015.
HULL PUMP SWINGING LADDER DREDGE

With the option of two front-swing winches, the Barracuda Class is a two-in-one dredge that easily converts from a swinging ladder to conventional mode with no sacrifice of portability. Starting with our base model, we customize the Barracuda for your specific application, learning all details of your project, and involving you every step of the way.

The Lake Panorama Rural Improvement Zone, located in Panora, Iowa, about 45 minutes west of Des Moines, maintains the largest private lake in Iowa. With 1,400 acres of lake surface, more than 30 miles of shoreline, 1,000 homes and approximately 200,000 to 300,000 cubic yards of silt to dredge each year, Lake Panorama was in need of upgraded equipment to meet the specific dredging needs of the area.
The Gila River in Arizona is a very important source of irrigation water for the entire Gila River area south of Phoenix, including the Gila River Indian Community, but it carries quite a bit of sediment, which can cause blockage and separation. The San Carlos Irrigation and Drainage District (SCIDD) addressed the sediment problem by redirecting the river water through the 1,800-foot long, 100-foot-wide Florence-Casa Grande Canal, near Coolidge, Arizona, where the sediment was then trapped in a 15-foot-deep settling basin.
