DELAVAN INLET
PROJECT PROFILE:
Dredging and Dewatering
Delavan Lake is 2,072 acres, about 60 feet at its deepest, and is both fed and drained by Jackson Creek, a tributary of Turtle Creek. Over time, the inlet had become clogged with so much sediment that it lost about 56 percent of its natural storage capacity and became less effective at cleansing the water flowing into the lake. In May 2011, JND Thomas Company, Inc. (JND) was selected by the town committee of Delavan to be prime contractor for the dredging and dewatering project because of JND’ s water borne environmental and commercial remediation expertise and due to the stringent return water quality standards required in the Delavan Inlet project.
The work required coordination with local authorities and residents near the fire station and adjacent retirement housing complex and the ongoing maintenance of submerged pipeline within Delavan Lake as to not interfere with recreational boating or access to any of the lakes facilities or launching ramps.
