Michels Construction, Inc. and Michels Road & Stone, Inc. built 4.3 miles of stone dike ranging from 4 to 8 feet high on the Green Bay lake bed to reconstruct the Cat Islands Chain. Additionally, Michels crews also built a 275-foot mooring facility and were responsible for building the dike to exact specifications for height, width and shape. Building the mooring facility required sheets and pilings to get drilled into the lake bed.
Michels recreated the chain by essentially building a curvy stone dike with three cells created by six legs of core stone and armor stone extending off the main dike. About 800,000 tons of dense base and 300,000 tons of armor stone, provided by Michels, were used to build the dike.
The bays will be used as dredged material disposal facilities with 20 years of capacity for sediments from the upper portion of Green Bay's navigation channel. When filled, the bays will eventually become the three islands that are expected to foster vegetation and habitat for fish and wildlife. Michels completed this project three years ahead of the contractual completion date schedule.
