A park bench, bicycles,lily pads, rocks and other items are being found in the muck of Lakeside Park lagoons as a dredging project continues.
About 1½ miles of tubes are transporting water, liquified mud and other ground items from the lagoons to an area on the west end of the park property.
About 60 residents turned out for a meeting Tuesday afternoon at the Lakeside Park Pavilion that provided an update on the project. Fond du Lac Public Works Director Jordan Skiff, City Engineer Paul De Vries and Kent Petersen, owner of PCI Dredging based in Minocqua, were on hand to explain the work.
“This has been a good project,” Petersen said, adding that the park setting without houses at the banks has made it easier to maneuver equipment.
Hydraulic dredging involves use of barges with claw-like arms that dig the material and send it in pipes to an area where water and solids are separated.
The first phase of work is nearly complete. Crews have been working around the clock in an area south of the Promen Drive bridge. That area was nearly clogged with sediment washing in from Lake Winnebago.
PCI Dredging plans to shut operations down after this week. Work is likely to resume in March with completion scheduled for May.
“The cold weather is a challenge,” Petersen said. “We’ve proven we can work in minus-7 (degrees).”
Petersen showed residents jars of clay balls and rocks that clog equipment on a regular basis. He said the machines pump about 2,500 to 3,000 gallons of diluted material a minute.
The dredged material is being stored in an open pit at Lakeside West. Residents are asked to stay away from the storage area.
