This data was collected as part of the AKSSF funding #4634 awarded to the Alaska Department of Fish and Game, Sportfish division in Region III. The Salcha River, located outside of Fairbanks, Alaska, is home to the largest spawning population of Chinook salmon in the U.S. portion of the Yukon River drainage. Tower techniques were used in the Salcha River to establish an escapement estimate and carcass surveys were conducted to collect age, sex and length data to assess run compositions. The data in this spreadsheet includes separate tabs for daily passage estimates with uncertainty and final estimate for each year of the project (2017-2019) and a single tab with all years of the data collected during carcass surveys. The citiation for the operational plan for this project is below: Stuby, L., and M. Tyers. 2016.
