Cool, low water sets up a dawn-and-dusk fall pattern

What's next

The New Moon means dark nights and no moonlight at first light, so the first and last hour of daylight are the windows worth planning around. Cool water at 52 to 54°F usually keeps fish comfortable through the day, but the best activity typically comes when light is lowest.

With flows this low, the small streams will hold clear and stay low until rain arrives. Expect fish to stay concentrated in whatever depth and cover the channel offers. Longer, finer presentations should out-fish anything heavy. On the warmer, tidal river stretch at 64°F, plan around the turn of the tide and watch for the flow reading to swing back positive.

Fishing the Midwest notes that as weeds die back in fall, fish relocate to the green weeds that remain. That is a general fall pattern, so look for the last live vegetation and the edges of hard cover when you scout a new spot. Check state regulations and any seasonal closures before you head out.

Context

Early to mid October is typically a transition period for Pacific Northwest freshwater. Summer warmth has left the smaller streams, and the first sustained fall rains usually start to lift flows and bring fresh fish into the system. Right now the water is on the low, clear side of that shift, which is normal before the first big rain. Readings of 52 to 54°F in small streams are consistent with the season. The 64°F reading on the larger river is also normal, since big, slow water holds summer heat longer than the creeks feeding it.
