The distribution, contribution, and value of artificially propagated fall chinook on the Columbia River was determined. Total returns of fall chinook to Columbia River facilities in 1984 were 74,401. This was the second smallest return over the past five years. Returns to Bonneville, Spring Creek, Little White Salmon, Klickitat and Klaskanine hatcheries were smaller than any previous year during this study. However, returns to Priest Rapids and Sea Resources hatcheries were greater than in previous years. Final estimated catch values are available through 1982 for British Columbia, Washington, Oregon and Columbia River fisheries. Fall chinook from the Columbia River hatcheries are predominately recovered in these fisheries. The percentages of the 1978-brood fish caught in these fisheries was 40.3, 35.0, 7.5 and 17.2 respectively. Contributions to the fisheries per 1000 fish released for all hatcheries combined were 2.6 and 3.0 for the 1978 and 1979 broods respectively. Three years (1980 to 1982) were included in the contribution values for the 1978 brood and two years (1981 and 1982) for the 1979 brood. Spring Creek Hatchery had the greatest contribution to the fisheries of 8.2 and 12.7 fish per 1000 fish released for the 1978 and 1979-broods respectively. The Spring Creek contribution was followed by Stayton Pond, Abernathy, Bonneville and Big Creek at 6.3, 4.1, 2.9 and 2.6 respectively for the 1978 brood and Big Creek, Stayton Pond and Abernathy at 7.4, 6.2 and 3.9 respectively for the 1979 brood. Other facilities had contributions per 1000 releases of less than 2. These contributions are minimums since all possible catch years are not included. 2 figs., 36 tabs.
