    Landsburg Fish Ladder Annual Salmon Counts

    Metadata Updated: September 20, 2025

    The Landsburg Fish Ladder was constructed in 2003 at the Landsburg Diversion Dam at River Mile 23 on the Cedar River. Data includes annual (Return Year) salmon counts by species as well as by sex and adipose fin status, where known. Fish counts are obtained either through manual sorting (Sorted) or by analyzing fish camera videos (Fish Camera). Data are collected as part of the Habitat Conservation Plan and Landsburg Mitigation Agreement.

    Methods and data summaries are available in the Fish Ladder Annual Reports (SPU).
