This contract period from Feb. 1, 2018 through Jan. 31, 2019 would continue programmatic objectives for the coho reintroduction program. M&E activities include survival measures and data collection for status and trend analyses of the coho program; both within year and for long-term comparisons. Coho abundance and egg-to-immigrant survival (through the use of smolt traps) for naturally produced juveniles on both Nason Creek as well as the lower Wenatchee River trap (operated by WDFW) allows for us to calculate smolt-to-adult rates for natural origin returns.  Hatchery in-pond acclimation survival as well as out-migrant run timing is critical in determining that volitional releases are the most appropriate means for releases of coho in both Methow and Wenatchee basins.   On the adult returns, escapement methods to be calculated will involve spawning ground surveys to determine spawning timing, distribution and H vs. N origin compositions.
Activities covered under this contract would relate to tagging/marking of juveniles in the form of:
- CWT'ing/BT'ing/PBT analysis/PIT tagging (the first 3 would provide information in determining SARs and the last one would be for in-pond and Columbia corridor survivals as juveniles)
- Data analysis for adult distribution, run composition, spawning densities and locations, M vs F ratios, run timing, fecundities, etc.  (activities to contribute to this would occur on SG surveys and at spawning).
- Juvenile run timing, outmigration survival and abundance (via the rotary ST on Nason Cr. as well as the WDFW operated Cashmere ST)
