Fish Passage Barrier Removal at Deep Cliff Golf Course in Cupertino

The Friends of Stevens Creek Trail has created a partnership with the cities of Mountain View, Cupertino, Sunnyvale and Los Altos, as well as the County of Santa Clara, Midpeninsula Regional Open Space District and Deep Cliff Golf Course. Together we provided matching funding to qualify for a grant from Valley Water for implementing a Stevens Creek Steelhead Passage Improvement Project. The plan is to remove a low water vehicle crossing that creates a passage barrier for juvenile steelhead (Oncorhynchus mykiss), a federally listed threatened species. The barrier is located one mile downstream of Stevens Creek Reservoir, in the Deep Cliff Golf Course in Cupertino.

Stevens Creek supports a population of federally listed steelhead. Below the Stevens Creek Reservoir the creek is a designated critical habitat for Central California Coast steelhead. According to studies, regional steelhead populations have declined to an estimated 10% of their historical abundance and steelhead in Bay Area streams are at continued risk of extinction due to multiple factors including impassable dams, large drop structures, flat bottom culverts, urbanization, reduced flows, and degraded water quality.

The project is expected to be completed before the end of 2021.
