Slayden helped modernize the aging fish collection facility on the North Santiam River, an essential site used to safely trap and transport ESA listed fish around Detroit and Big Cliff dams. Located between State Highway 22 and the riverbank, this high profile project required ongoing coordination with numerous regulatory partners, including NOAA, NMFS, USACE, ODFW, DEQ, ODSL, and ODOT, to ensure environmental protection and seamless execution.
Building the new facilities required major excavation and concrete construction below river level. Slayden installed an extensive cofferdam system and diversion channel to fully isolate the right bank, creating a safe, dry work zone while protecting river habitat. In water work also included concurrent repairs to the adjacent barrier dam. The completed improvements support long term fish recovery efforts and reflect Slayden’s commitment to preserving the natural resources that define the Pacific Northwest.
Slayden earned First Place in the 2025 AGC Construction Safety Excellence Awards (CSEA) in the Utility Infrastructure Category — Under 500,000 Work Hours.
