San Francisquito Creek Stabilization at Bonde Weir Project

This project removes Bonde Weir, a significant fish migration barrier in San Francisquito Creek, and constructed a new channel design to improve fish migration, stabilize the channel and reduce erosion. The new channel restores access to 40 upstream miles of steelhead spawning and rearing habitat.
