Enhancing habitat for restoring and maintaining a healthier and more resilient Upper Mississippi River Ecosystem
Restoring habitat is one of two major focus areas of the Upper Mississippi River Restoration (UMRR) Program. The Habitat Rehabilitation and Enhancement Project (HREP) element utilizes a wide range of construction techniques and approaches that mimic natural river processes and provide benefits to the river system at the system, reach, pool, and local scales.
Each restoration project is multi-faceted, enhances many types of habitats and species, and addresses specific ecological goals that are identified through a comprehensive planning process. HREPs use a variety of restoration techniques including shoreline protection, island creation, water level management, backwater dredging, secondary channel modifications, aeration, and floodplain and tributary restoration. Planning teams for restoration projects utilize ecosystem understanding and long-term monitoring data provided by the Science and Monitoring element of UMRR to identify problems and to improve project effectiveness.
Our projects continually build upon experience gained from construction, management, and monitoring of prior projects and the UMRR’s foundation partner coordination. UMRR is constantly enhancing its restoration techniques and incorporating new research findings to improve habitat benefits to project costs ratios. The 2006 Environmental Design Handbook and the 2012 update capture this learning, documents UMRR’s approach to adaptive management, and facilitates the transfer of knowledge and experience within and beyond UMRR, key elements of the program’s success.
The HREP element has fostered interdisciplinary and collaborative planning for habitat restoration, preservation, and enhancement previously non-existent on any other river system in the United States.
St. Paul District restores habitat on the Mississippi River above Lock and Dam 10 at Guttenberg, Iowa (Pools 10 and above).
Rock Island District restores habitat on the Mississippi River between Lock and Dam 10 and Lock and Dam 22 at Saverton, Missouri, (Pools 11 through 22); and on the Illinois Waterway above river mile 80 (including LaGrange and Peoria Pools).
St. Louis District restores habitat on the Mississippi River south of Lock and Dam 22 to Cairo, Illinois.
