Project Experience

Stabilized shoreline with stone buffering

Crispin Drain and Cuttle Creek

Habitat restoration designs were developed for multiple sites. Design features included shoreline stabilization, shoreline buffer restoration, near-shore substrate restoration, shoreline processes assessment, habitat restoration, stream restoration of over 3,000 linear feet of tributaries, and habitat enhancements in over 2 miles of county drain habitats.

Fox River

EA assisted Kaukauna Utilities with licensing-related natural resources studies and associated natural resources support for relicensing facilities. The work has involved seasonal fish and qualitative mussel surveys; removal and relocation of fish and mussels that would be stranded by construction-related dewatering; and review of potentially contaminated sediment, downstream aquatic habitat, general wildlife use, aquatic and terrestrial invasive species, benthic macroinvertebrates, fish, and water quality assessments.

Turtle Creek Reservoir

For more than 4 decades, EA has supported a power utility company with a local generating station via management of the 1600-acre Turtle Creek Reservoir. Scientists have performed annual biomonitoring, including fisheries surveys focused on primary production and a myriad of related aspects such as phyto/zoo plankton, benthic invertebrates, sediment and water chemistry, fish tissue, growth analysis, invasive species, watershed health and habitat inventories for the fish community.
