Project Overview
This 3.62 acre site was a former 1960’s borrow pit used for the construction of the Illinois Tollway. There are 199 acres tributary to the Dalitsch pond. Based on its location, the pond was identified as having potential to filter and improve water quality entering the Middlefork Savanna Wetland. The objective of the project was to preserve and protect the high quality Middlefork Savanna Wetland by improving water quality entering the wetland. The Middlefork Savanna is considered the highest quality tallgrass savanna of its kind in the nation. The site also provides habitat for the Blanding’s turtle, a threatened and endangered species.
Dalitsch Pond Enhancement Bleck Engineering
The project included converting the existing pond into an emergent complex. This was accomplished by raising the bottom elevation of the pond and creating varying planting zones including:
    • Blanding Turtle Habitat (deep open water)
    • Aquatic
    • Emergent
    • Upland Dry Prairie
    • Wet Prairie (shallow mudflats)
Beck Stormwater Management Dalitsch Pond Enhancement
Shallow mudflats were used to maximize the flow path length from the primary inlet to the outlet. Funding sources included IEPA 319 Grant, Lake County Stormwater Management Commission - Wetland Restoration Fund, City of Lake Forest, Lake County Forest Preserve, and Lake Forest Open Lands.
