The town manager has been having fun with the process, donning a skipper hat to lead a boat tour of the operation for local media and representatives from the Crown Point Community Foundation including its president, Mary Nielsen. Officials expect the lake will gain about two to three feet in depth in the shallow areas once the dredging is complete, Salatas said. It takes about three minutes for the material to get to the dewatering facility.Ĭurrently, Cedar Lake averages about 6 feet deep with the deepest section of the lake coming in at about 12 feet deep. About 6,000 gallons of sediment per minute pumps through the hose at a speed of about 60 miles per hour. Town Manager Chris Salatas said it takes three hydraulic pumps to suck the muck from the lake bottom and force it through three miles of pipe - two miles in the water and one underground - to the dewatering facility at 151st Avenue and Parrish Street. The barge is 82-feet long with its cutter head, a giant drill that penetrates the sediment, pivoting back and forth to loosen it up so it can be sucked up through the pump and moved out of the lake. On June 9, the Poseidon began the three-year process of dredging the bottom of Cedar Lake in an effort to removed hundreds of thousands of cubic yards of sediment from the lake floor. Now, more than three decades of efforts to divert polluted run-off from the lake has begun to pay off and the town has officially embarked on a generational dredging project that is expected to improve water quality and aquatic life of the lake and bodies of water downstream.
