PROJECT INFORMATION
The Navigation and Ecosystem Sustainability Program (NESP) is a long-term, dual-purpose program that aims to increase the capacity and reliability of the inland navigation system while restoring, protecting and enhancing the environment of the Upper Mississippi River System.
The Liverpool Side Channel Ecosystem Restoration Project fits within the larger NESP goal by aiming to maintain, enhance and restore quality habitat for native and desirable plant, animal and fish species and maintain, enhance, restore and emulate natural river processes, structures and functions for a resilient and sustainable ecosystem. The proposed Project would: (1) increase deep-water overwintering fish habitat, and (2) increase island topographic diversity to increase forest resilience and diversity.
Measures and features proposed for the Project would include:
- Dredging for backwater depth diversity and connectivity
- Restoration of overwintering habitat
- Construction of River Training Structures
- Dredged material placement
The purpose of this PIR/EA is to document existing conditions, evaluate potential impacts associated with each alternative, and assists in planning and decision making for the Liverpool Side Channel Ecosystem Restoration Project.
