IMPERIAL DAM DREDGING AND RECHARGE POND REHABILITATION LAGUNA SETTLING BASIN 

Yuma, AZ              

CJW Construction, Inc. performed the maintenance dredging along the overflow weir from the headworks of the All American Canal and north along the Colorado River channel, along the face of the dam and weir, and north of the secondary river channel above the Gila Sluiceway adjacent to Hidden Shores (formerly Imperial Oasis) on the Arizona side of the river channel. CJW dredged sediment from the Colorado River near Yuma AZ, pumping the sand material to a spreading ground that CJW cleared and managed during the discharge.

​CJW worked closely with a manufacture in Topeka Kansas to custom design/build a new Dredge and Booster that produces 3,500hp and pumps well over 12,000gpm. CJW pumped over 11,600 cubic yards per shift, with daily quantity accurately tracked via a nuclear densitometer, calibrated and confirmed by hydrographic surveys.
