Pinole Creek Fish Passage Improvements project at I-80 Culverts

This project will construct fish passage improvements at the 320-ft long CalTrans I-80 double bay box culvert on Pinole Creek, which is the only major barrier to upstream passage of juvenile and adult steelhead trout. When implemented, these improvements will restore anadromous steelhead access to approximately 7 miles of quality spawning and rearing habitat.

This project will construct fish passage improvements at the 320-ft long CalTrans I-80 double bay box culvert on Pinole Creek, which is the only major barrier to upstream passage of juvenile and adult steelhead trout. Major elements include cutting and reforming a concrete fishway notch through the upper half of the western culvert bay and adding a notched sill on the downstream end to backwater the lower half of the culvert.

The project will allow steelhead to access quality habitat in the protected upper Pinole Creek watershed. Habitat assessments have identified the I-80 culvert as the only substantial barrier for migrating steelhead attempting to access spawning habitat upstream. Improved access at this culvert will open approximately 7 miles of suitable spawning and rearing habitat upstream to the species as noted in habitat mapping studies (see related documents). Steelhead are currently unable to pass the I-80 culverts during the majority of flows experienced during the spawning season. As a result, steelhead are only able to successfully reproduce in Pinole Creek on rare occasions when flow conditions allow passage at this structure. A healthy resident rainbow trout population in the upper watershed points to the stream's habitat suitability for supporting anadromous steelhead runs. Completion of the project will result in an increased steelhead population in the protected upper watershed and within the Pinole city limits. Increases in anadromous fish populations in Pinole Creek will benefit aquatic and terrestrial species throughout the watershed and contribute to the recovery of Central California Coast Steelhead

Part 2 - Detail

The project concept consists of 2 major elements at the I-80 culverts:  (1) cutting and reforming a concrete fishway notch through the 36-ft long inlet apron and within the upper 148 feet of the western culvert bay and forming 13 concrete angled fish baffles within the fishway notch; constructing concrete training walls on the inlet and outlet apron; adding a notched sill on the downstream end of the outlet apron to backwater the lower half of the western culvert bay, and (2) constructing a 60 ft long roughened rock chute in the flood control channel downstream of the existing culvert outlet pool to prevent the formation of a drop at the culvert outlet that could limit upstream fish passage.

San Pablo Bay, San Francisco Bay and Pinole Creek

The CalTrans I-80 double bay box culvert on Pinole Creek creates a severe barrier to upstream passage of juvenile and adult steelhead trout. This is the only substantial fish barrier on Pinole Creek and the fish passage improvements project will enable steelhead to reach the quality spawning and rearing habitat found in the upper watershed and improve the potential for successful spawning.  Re-establishment of a sustainable population of anadromous steelhead trout would help to restore the genetic diversity, geographic distribution and viability of this Federally listed threatened species.

If the proposal is not implemented, the box culvert will continue to block upstream passage of anadromous steelhead at nearly all flows, denying fish access to quality spawning and rearing habitat in the upper watershed. The culvert will continue to be a major limiting factor to the steelhead population in Pinole Creek.
