    • Fish and logger summaries - Physical and biological effects of fish-friendly tide gates

    Metadata Updated: October 18, 2025

    The purpose of this one-time stand-alone study is to evaluate how effective "fish-friendly" or self-regulating tide gates (SRTs) are at increasing connectivity for fish rearing in estuaries. The work was carried out in North Puget Sound, Washington Coast, and Columbia River estuaries by Correigh Greene, Jason Hall, and Eric Beamer (Skagit River System Cooperative), and compared SRTs with traditional flap gates and reference sites that were not blocked by any tide gate. Thus far, the study has produced a report for ESRP (Estuary Salmon Restoration Program), the organization that funded it. Up to two peer-reviewed papers are planned. The audience for this work includes federal and state managers, local planners, Watershed Councils, and applied ecologists. Excel datasheets of fish and logger summaries.
