SR 532 - Pilchuck Creek Tributary (Secret Creek) - Fish Barrier - Complete September 2016

WSDOT installed a new culvert to carry Secret Creek under SR 532. The new culvert measures 18 feet wide, 10 feet high, and 195 feet long and provides better passage for fish like salmon and steelhead.


How you benefit

Protects environment
The new culvert replaces an old four-foot diameter culvert that posed a barrier for fish. The new culvert provides about three more miles of habitat for salmon and steelhead. The streambed was also rebuilt which creates a more inviting habitat for other wildlife. Replacing the culvert helps WSDOT meet a federal court order to remove state-owned culverts that block fish passage.


Partnerships & cooperation
WSDOT worked with the city of Stanwood, local businesses and the freight community when planning the work. 


2005 Gas Tax (TPA): $1,767,000
