Gazos Creek Watershed Improvements Project - Phase 1

Gazos Creek Watershed Improvements Project - Phase 1

The applicant proposes to make watershed improvements at several locations throughout the Gazos Creek watershed in unincorporated San Mateo County. Both federally threatened steelhead and federally endangered coho salmon are present in Gazos Creek. The proposed project involves bank repair and debris management at the location of a large redwood tree fall and modifications to five logjams to improve migration to upstream spawning and rearing habitat for steelhead and coho salmon and protect the adjacent roadway. The work is designed to improve fish passage and bank and roadway stability while also preserving rearing and over wintering habitat that is provided by the large in-channel wood and associated pools. The proposed modification method does not involve complete removal of the logjams but rather clearing a path for stream flow. Large rootwads and conifers providing habitat will not be removed. Sections of very large spanner logs will be strategically cut to promote flow. Some wood will be removed and placed against the banks for protection. Smaller non-conifer wood and debris may be moved onto the adjacent terraces above ordinary high water level.
