The fish was caught on a Zonar Blade Bait, I have not tried true jigging spoons, another bait that works are Storm Wild Eye jigs (4″ firetiger or rainbow trout)
That is the best time to fish the Columbia River. February and March, the females are plump, just lying in the silt on the flats waiting for a tempting jig to hit thme in the face. Quality fish are worth slowing down for.
