Description
- Abstract: This study was designed to document and describe the status and life history strategies of spring Chinook salmon and summer steelhead in the Grande Ronde River Subbasin. We determined migration timing, abundance, and life-stage survival rates for juvenile spring Chinook salmon Oncorhynchus tshawytscha and summer steelhead O. mykiss in four streams in the subbasin during migratory year 2007 from 1 July 2006 through 30 June 2007. As observed in previous years of this study, spring Chinook salmon and steelhead exhibited fall and spring movements out of their natal rearing areas,
but did not begin their smolt migration through the Snake and lower Columbia River hydrosystem until spring. In this report we provide estimates of abundance and timing of migrants leaving each study stream, their survival and timing to Lower Granite Dam, and estimates of abundance of spring Chinook salmon parr and summer steelhead parr in Catherine Creek and spring Chinook salmon parr in Lostine River during summer. We also document aquatic habitat conditions using water temperature and stream flow in four study streams in the subbasin. ODFW, Eastern Oregon Fish Research (EOFR)

- Purpose: 1. Document the in-basin migration patterns and estimate egg-to-migrant survival for
spring Chinook salmon juveniles in Catherine Creek and the upper Grande Ronde,
Minam, and Lostine rivers.
2. Determine overwinter mortality and the relative success of fall (early) migrant and
spring (late) migrant life history strategies for spring Chinook salmon from tributary
populations in Catherine Creek and the upper Grande Ronde, and Lostine rivers, and
the relative success of fall (early) migrant and spring (late) migrant life history
strategies for spring Chinook salmon from the Minam River.
3. Estimate and compare smolt survival probabilities at main stem Columbia and Snake
River dams for migrants from four local, natural populations of spring Chinook
salmon in the Grande Ronde River and Imnaha River subbasins.
4. Document the annual migration patterns for spring Chinook salmon juveniles from
four local, natural populations in the Grande Ronde River and Imnaha River
subbasins: Catherine Creek, Lostine, Minam, and Imnaha rivers.
5. Document patterns of movement for juvenile steelhead from tributary populations in
Catherine Creek, the upper Grande Ronde, Lostine and the Minam rivers including
data on migration timing, duration, and smolt abundance.
6. Estimate and compare survival probabilities to main stem Columbia and Snake River
dams for summer steelhead from four tributary populations: Catherine Creek and the
upper Grande Ronde, Lostine, and Minam rivers.
7. Evaluate methods to estimate the proportion of steelhead captured during fall trapping
that are migrating out of rearing areas and will undertake a smolt migration the
following spring.
