  • Weaver Basin Fish Passage Assessments

    This project assessed 37 unassessed or unknown-status fish passage barriers in the Weaver Creek watershed, a headwater tributary to the Trinity River near Weaverville in Trinity County, to provide baseline data for future fish passage remediation projects benefiting Coho salmon, steelhead, Chinook salmon, and Pacific lamprey, while engaging local students and tribal partners in the assessment process.

  • West Tule Creek Diversion Fish Passage Project

    This project developed engineering designs for a fish-passable irrigation diversion and fish screen on West Tule Creek, a tributary to Hayfork Creek in Trinity County, to restore 1.5 miles of upstream spawning and rearing habitat for Chinook salmon, coho salmon, steelhead, and Pacific lamprey, while also improving instream flows through water transaction and irrigation efficiency upgrades on the Evans Ranch.

  • Sharber-Peckham Fish Passage Project

    This project replaced a failing undersized corrugated metal pipe culvert on Galaxy Drive, which had blocked Sharber-Peckham Creek — a Trinity River tributary near Salyer in Trinity County — for at least 20 years. The barrier was replaced with a 12-by-14-foot embedded multi-plate ellipse culvert designed to pass 100-year flows while maintaining a natural streambed. Sharber-Peckham Creek is the greatest single producer of coho salmon between the Hoopa reservation and the North Fork Trinity River, and post-project monitoring found 740 juvenile coho rearing upstream within one year.

  • Conner Creek Migration Barrier Removal Project

    This project addresses two fish passage barriers on Conner Creek, a tributary to the Trinity River below Lewiston Dam. The Trinity River is a major tributary to the Klamath River. The project sites — Conner Creek Road (Crossing #1) and Red Hill Road (Crossing #2) — are located approximately 8 miles west of Weaverville in Trinity County, California.
