Appendix 1 List A

Summary of Life History Characteristics for Wild Spring and Summer Chinook Salmon of the Snake River Excluding the Clearwater River

Age at spawning
- a. Tucannon River: data limited; mostly 2-ocean adults (Howell et al. 1985).
- b. Grande Ronde River: varies by stream, but 2-ocean adults tend to predominate (Howell et al. 1985).
- c. South Fork Salmon River: extremely variable; 2-ocean adult returns were always higher than 3-ocean adult returns from 1960 to 1967 (Howell et al. 1985); jacks (1- ocean males) predominated during two of those years.
- d. Middle Fork Salmon River: 2-ocean male and 3-ocean female adults predominate (Howell et al. 1985); tend to return as 3-ocean adults (CBFWA 1990).
- e. Upper Salmon River: 3-ocean adults predominated during the early 1960s, especially in females (Howell et al. 1985).
- f. Imnaha River: from 1961 through 1976, adult returns averaged 5% jacks, 44% 2- ocean, and 50% 3-ocean (Howell et al. 1985); in 1984, only 37% of sampled fish were 3-ocean (Carmichael and Messmer 1985).
Sex ratio
- a. Tucannon River: female/male 1:1 in 1986 and 1.2:1 in 1987 (CBFWA 1990).
- b. Grande Ronde River: information limited and questionable due to recovery techniques (trapping only portions of runs). In 1982 and 1983, female/male 1.2:1 and 1.9:1, respectively (Howell et al. 1985).
- c. South Fork Salmon River: from 1964 through 1967, female/male averaged 0.5:1 (Howell et al. 1985).
- d. Middle Fork Salmon River: female/male ranged from 1:1 to 1.3:1 from 1961 through 1964 (Howell et al. 1985).
- e. Upper Salmon River: female/male averaged 1:1 from 1961 through 1964 (Howell et al. 1985).
- f. Imnaha River: from 1961 through 1974, female/male averaged 0.6:1 (CBFWA 1990).
Fecundity
- a. Tucannon River: mean of 3,916 and 4,095 eggs/female in 1986 and 1987, respectively (CBFWA 1990).
- b. Grande Ronde River: mean of 3,715 and 3,462 eggs/female in 1983 and 1984, respectively (Howell et al. 1985).
- c. South Fork Salmon River: mean of 3,685 to 4,412 eggs/female from 1980 through 1984 (Howell et al. 1985).
- d. Middle Fork Salmon River: mean of 5,511 and 5,839 eggs/female in 1963 and 1964, respectively, for Bear Valley and Elk Creeks only (Howell et al. 1985).
- e. Upper Salmon River: mean of 5,894 eggs/female from 1981 through 1984 (Howell et al. 1985).
- f. Imnaha River: mean of 5,286 and 4,709 eggs/female in 1983 and 1984, respectively (Howell et al. 1985).
Egg to smolt survival
- a. Tucannon River: 13% for 1985 brood year (CBFWA 1990); 14% for 1987 brood year (Bugert et al. 1990).
- b. Grande Ronde River: varied from 6 to 19% from 1965 through 1969 (Howell et al. 1985).
- c. South Fork Salmon River: no information.
- d. Middle Fork Salmon River: no information.
- e. Upper Salmon River: from 1965 through 1974, averaged 9.7% for Lemhi River (CBFWA 1990).
- f. Imnaha River: no information.
Smolt to adult survival
No data are available for individual streams or drainages. However, Raymond (1979) estimated 4-5% smolt-to-adult survival for wild smolts arriving at Ice Harbor Dam from 1966 to 1968. From 1969 to 1975, survival ranged from 0.4 to 3.5%. These estimates do not take into account any smolt mortality between rearing areas and the first dams.
Smolt migration timing at dams
- a. Tucannon River: no information.
- b. Grande Ronde River: in 1989, smolts at Lower Granite Dam between early May and late June, peaking about 9 June (Matthews et al. 1990).
- c. South Fork Salmon River: in 1989, smolts at Lower Granite Dam from early April through June, with peaks on 25 April and 10 May (Matthews et al. 1990); in 1990, at the dam from early April through mid-May, peaking about 14 April (preliminary NMFS data).
- d. Middle Fork Salmon River: no information for 1989; in 1990, smolts at Lower Granite Dam from early April through June, peaking in late April and again in late May (preliminary NMFS data).
- e. Upper Salmon River: in 1989, smolts at Lower Granite Dam from early April through mid-June, peaking in early May (Matthews et al. 1990); in 1990, smolts from early April through mid-June, peaking twice on 19 April and 31 May (preliminary NMFS data).
- f. Imnaha River: in 1989, smolts at Lower Granite Dam from early April through May, peaking the first week of May (Matthews et al. 1990); in 1990, smolts at the dam from early April through early May, peaking in early April (preliminary NMFS data).
Adult run-timing
- a. Tucannon River: exact timing unknown, but expected to be similar to other upriver spring chinook salmon stocks where adult freshwater entry occurs from mid-March through April (Howell et al. 1985).
- b. Grande Ronde River: most adults destined for this river pass Bonneville Dam in April and May (Howell et al. 1985).
- c. South Fork Salmon River: adults enter Columbia River in June and July (CBFWA 1990).
- d. Middle Fork Salmon River: exact timing of adults over Bonneville Dam unknown; for spring chinook salmon, expected to be from mid-March through May and for summer chinook salmon, expected to be from June through July (CBFWA 1990).
- e. Upper Salmon River: same as for Middle Fork Salmon River (CBFWA 1990).
- f. Imnaha River: adults pass Bonneville Dam from mid-April through July (Howell et al. 1985).
