White Lake Dock & Dredge, a division of ENTACT, performed remedial activities at Pickle Pond, a nine-acre urban pond situated in the St. Louis River lower estuary. This project aimed to enhance the habitat for local wildlife, including waterfowl, beavers, and otters, while addressing sediment contamination. During this project, our team:

• Dredged more than 16,000 cubic yards of contaminated sediments composed of fine-grained silty clays
• Solidified dredged materials by applying a non-toxic super absorbent polymer to reduce excess water, allowing for direct loading into trucks for offsite disposal
• Treated water to ensure environmental safety
• Demolished railroad structures
• Constructed an armored spillway channel to enhance water management
• Implemented dust and odor control measures

Wetland Creation: Following sediment removal, an additional 21,000 cubic yards of dredged material was used to form a wetland base within the work area. To create the wetland area, ENTACT:

• Re-planted more than 11 acres of with various emerging wetlands and plug plantings
• Enhanced habitats to support local wildlife

Additional Project Components

• Water treatment to ensure environmental safety
• Demolition of railroad structures
• Construction of an armored spillway channel for enhanced water management
• Implementation of dust and odor control measures

This project significantly improved habitat conditions for fish, birds, and turtles, controlled invasive species, increased recreational opportunities for non-motorized watersports, reduced runoff pollution, and enhanced water flow between Pickle Pond and adjacent Barker’s Bay.
