The king salmon returning to the Columbia River this month could ultimately number about 333,000 fish, an outstanding number which would be the second largest run on record. The Lower Columbia sport-fishery below Bonneville Dam should remain open until May. Drop anchor on the outgoing tide and fish spinners and plugs behind the boat in water 12 to 30 feet deep. During slack tide, troll herring or sardine-wrapped Kwikfish or Flatfish in silver and chartreuse or gold and red. Bank-fishing just below the dam using Spin-N-Glos is also popular. In the lower tidal-influenced section of river, the best action occurs the hour before, during and after the high and low slack tides. From the I-205 bridge upriver to Bonneville Dam, anglers usually anchor next to the jetties and use pink prawns rigged with beads or small gold blades.
