• Where to Fish on Rainbow Reservoirs

  No figure exists for depth, so let the water show you. Look for the band where the shallows give up and the bottom falls away. Read the surface for the wind lane, then fish the edge of it. Union County records list rainbow trout, brook trout, Chinook salmon, brown bullhead and black crappie among the fish reported. Protected fish appear in the records for this area, so treat the list as information, not an invitation. The near bank of Rainbow Reservoirs is often the one people ignore.

• Tackle & Baits

  We hold no note on access for this one. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Parking space is the usual limit rather than the bank itself. Fishing rules and camping rules are set separately here. For a change of water, Grande Ronde Lake is 6.6 miles distant. Rules at Rainbow Reservoirs are worth checking on the day.
