Featured Projects

Rodgers Dam:
NWRA Major project of the year - Rural (civil). Large flood flows and sand make this complex solution a winning civil engineering design... More
Penstock Replacement Project:
DEC provides On-call Dam design services working to manage dam capital improvements such as spillway and outlet works rehabilitation. This project is a replacement of 2 - 46" steel penstocks, options included carbon fiber lining systems.
Zunino Reservoir Rehabilitation Project:
DEC performed a fall dam rebuild including 2,400 feet of dikes for the State of Nevada. The Project was awarded runner up for project of the year 2015 by the Truckee Meadow ASCE. The project also included a 5-acre fish pond and bentonite cutoff trenching.  
Boca Dam:
DEC provides engineering services for the remediation of USBR controlled Boca Dam. Boca is a major dam on the Truckee River System. The Dam is being retrofitted for Seismic hazards, the PMF, and Security.
Knott Creek Dam:
Restrictions were placed on the dam and rehabilitation was required. DEC provided the Engineering Design and construction management for the rehabilitation of the dam.
