[env-trinity] 2025/26 CDFW Trinity River Project trapping summary through Julian week 38 (September 23)

[Van Vleet, Nicholas@Wildlife]

Hello, everyone,

Attached is the latest summary of the preliminary data for the Trinity River Project for the 2025/26 season with numbers from both Junction City and Willow Creek weirs, as well as the processed fish from the Trinity River Hatchery. The spreadsheet is up to date for both of the weirs, but the Trinity River Hatchery data for Julian week 38 has not been recorded electronically yet and is not included in this summary. Last week we successfully moved the boat gate at the Willow Creek weir to a more suitable location for our operations. Additionally, we installed a second trap box at the Willow Creek weir to better accommodate more of the run. On Monday we had our highest catch day in Willow Creek where we captured 192 individuals moving upstream, which was really great to see!
