THE DALLES, OR -- State biologists have determined that a number of dead and distressed sockeye salmon found this past weekend in the Deschutes River, appear to have died from a bacterial infection.
Early test results suggest the fish were from the Columbia River bound for upriver locations, and likely swam into the Deschutes in search of cooler water. However, the infection blamed for the deaths - Columnaris - is typically associated with warm water and/or low levels of dissolved oxygen.
