Onlyavery limited fishery took place immediately below The Dalle s Dam by Indians using dip nets. The blueback (sockeye) salmon run into the Columbia this year did not come up to expectations, but a preliminary reported catch of 255,000 pounds compares favorably with blueback catches in recent years. An estimated 156,000 blueback entered the river this year. Of this total, an escapement of 83,000 fish was counted over Bonneville Dam.
