LS Marine Inc., Grove Heights, Minn., was awarded a $7.7 million contract by the St. Paul Engineer District to use dredged material from the head of Lake Pepin to restore backwater river habitat near Bay City, Wis. The contract was awarded September 26. The project will use sand from the Mississippi River navigation channel and backwaters. Some of the key components of the project include building peninsulas, access dredging and shoreline protection to improve fish and wildlife habitat. Sedimentation has caused a loss of water depth diversity in the backwater lakes and isolated wetlands above Lake Pepin and has caused reduced habitat diversity and quality, lack of aquatic vegetation and invertebrates and reduced abundance of fish and wildlife, the St. Paul District said in announcing the contract. |
