Abstract:

Above–average losses of unspawned adult Chinook salmon at the Oxbow Dam holding pond on the Snake River have occurred coincidentally with higher water temperatures in two of the past three operating seasons.  In the season when lower water temperatures prevailed, fewer losses occurred. These events suggested that the lower temperatures benefited these fish.  In the fall of 1964 an experiment planned to investigate such benefits was attempted at the Oxbow hatchery.  Adult migrants trapped at the dam were held in water cooled by mechanical refrigeration.  The results are summarized in this report.
