Jensen wins contract to construct new diversion dam control structure at Saylorville Dam

Saylorville Lake

The U.S. Army Corps of Engineers has awarded a US$9.29 million contract to Jensen Construction Co. to construct a new diversion dam control structure at Iowa's Saylorville Dam.

The Corps' Rock Island District most recently solicited bids for the project in March, which also includes underwater boring through a concrete-filled corrugated metal pipe; construction of a sheet pile cofferdam and dewatering; removal of gate structure, sluice gate with manual and electrically operated gate operator, bulkhead gate and gratings; construction of a new reinforced concrete control structure housing a sluice gate and bulkhead gate and a three-girder concrete deck bridge; installation of riprap; removal and replacement of an asphalt bike path; and associated incidental work.

The Corps operates Saylorville Dam on the Des Moines River for flood control, water supply, recreation and wildlife habitat. Although the dam has no hydropower, a unit of Free Flow Power holds a Federal Energy Regulatory Commission preliminary permit to study developing the 14.4-MW Saylorville Dam Water Power project.
