Suscol Creek - concrete dam removal
Project Overview
Basics
Completed
We removed a small concrete dam upstream of the Highway 29 fish barrier, enhancing access to about 1.5 miles of critical habitat. This project, conducted under a programmatic permit, allowed for efficient and cost-effective removal of the barrier. Suscol Creek, a third-order tributary of the Napa River, extends approximately 9.35 miles and drains a 3.24-square-mile watershed. Ranging from sea level to 1,500 feet, the watershed features grasslands, oak woodlands, and vineyards, mostly on private lands. The creek is crucial for Napa Valley steelhead, providing high-quality spawning and rearing habitat for this imperiled species.

Project Themes
Project Themes
Removing the dam on Suscol Creek restores access to 1.5 miles of key habitat for steelhead trout. This enhances spawning and rearing opportunities, and improves overall creek health. The cost-effective, expedited process supports broader conservation efforts for similar projects.
The dam removal supports healthy watersheds by restoring natural sediment movement, improving habitat connectivity, and enhancing in-stream habitat quality.
