In December, 2002, Ross Laboratories, Inc. delivered a 34-foot boat with a Ross Mini-Sweep System to the Rock Island District, Corps of Engineers. It was the second boat Ross has delivered to the District in the past year.

The boat will be used for hydrographic surveying on the Mississippi River.

An acceptance team from the Corps Contracting and Field Office were in Seattle December 12 through 14 for sea trials on Lake Washington and to receive instruction on operating the boat and survey system.

The system works through hydraulically-operated booms mounted on the sides of the vessel, providing a 50-foot sweep width.

Electronics are stowed in two desktop cabinets, one containing the depth sounding system and the other a data collection computer and DGPS sub-meter system. Coastal Oceanographics HYPACK MAX and HYSWEEP software were installed for data collection and processing.

The Rock Island District is responsible for surveying on 314 miles of the Upper Mississippi River from Guttenberg, Iowa to Saverton, Missouri, and 268 miles of the Illinois Waterway from Lake Street in Downtown Chicago to the LaGrange Lock and Dam, southwest of Beardstown, Illinois. This new trailerable boat system will help District survey crews respond to critical surveys much faster, with only a two person crew.
