Samples of Current and Past Projects
THOMAS PUGH BRIDGE CONSTRUCTION
The West Virginia Division of Highways was replacing the Thomas Buford Pugh Memorial Bridge over the New River. ESI conducted a relocation, moving over 3000 mussels of 7 species. Most were tagged and relocated to two sites on the Monongahela River and one site on the Ohio River by the West Virginia Division of Natural Resources.
CoralvillE flood protection Project
The City of Coralville, Iowa constructed a floodwall to help protect the businesses near the Iowa River from future flood events. ESI surveyed the impact area for mussels, evaluated potential impacts from construction, and developed and implemented a mussel relocation and monitoring program in coordination with the Iowa Department of Natural Resources and the U. S. Fish & Wildlife Service.
Dubuque Generating Station 316(A) demonstration
In pursuit of a temperature variance for its cooling water effluent, the Dubuque Generating Station set out to demonstrate that the thermal effluent had not affected mussels in the Mississippi River near the discharge. ESI surveyed areas upstream and downstream of the discharge to determine whether the effluent had altered resident mussel communities.
Grand river restoration project
River Restoration plans to remove a series of lowhead dams on the Grand River in Grand Rapids, MI to benefit aquatic wildlife and provide recreation opportunities. ESI conducted an initial survey to identify mussel concentrations in this river reach; results of this survey will be used to aid in the project design. ESI is also assisting with preparation of a Habitat Conservation Plan (HCP) to satisfy state and federal regulatory requirements.
