The post spawn smallmouth bite is peaking right now on the Columbia with water temps in the low 60s. Perfect time for big fish there. The bite is aggressive, so crankbaits, senkos fished in a twitch and swim fashion, and top water are all working. A pal and I fished it last week. On the evening bite they were swirling on the baits as they splashed down. You would be hard pressed to catch anything under 1.5 pounds there right now. The big ones were on a feeding frenzy. Most of what we landed ran from 2-4 pounds. I'm not going to cite total numbers because no one would believe how many fish we caught in that size range. It was ludicrous.
