- Although sample sizes were small during the 1999 field season, we were able to verify at least some residual steelhead survive the winter to persist in the Clearwater River. Hatchery steelhead were found in low numbers migrating up tributaries of the Clearwater River where wild A-run steelhead spawn. Data from this first year did not indicate differences in survival due to size, release site, or rearing system for steelhead reared at Dworshak National Fish Hatchery. This information needs to be compared over several (at least three) years for meaningful analysis. Final analysis will also include influences of water flow and temperature in emigration success. Based on one year of data, the majority of steelhead which do not emigrate during the first couple of weeks after release, are unlikely to emigrate at all.
