| 摘要： | The U.S. Army Corps of Engineers, St. Paul District, awarded a $8.7 million contract to Newt Marine Service, Dubuque, Iowa, on July 14 for a Navigation and Ecosystem Sustainability Program, or NESP, project located on the Wisconsin side of the Upper Mississippi River in Upper Pool 4, near Bay City, Wis. The project, known as the Navigation Systemic Mitigation Island 4 project, aims to address general degradation of habitat quality due to sediment deposition, wind-driven wave action, declining changes in river bottom elevation and a decline in aquatic vegetation. Key project features include constructing a peninsula to improve habi- tat conditions by redirecting sediment and dredging in the winter to provide a deep-water habitat for fish. Willows, floodplain forest trees, and grasses will be planted on the islands to increase habitat diversity and quality. Construction is expected to start in the spring of 2024 and be completed by fall of 2026. |
