Eastern WA streams cool into fall, steelhead flies in focus

What's next

With temperatures in the upper 40s to low 50s, expect fish to hold in softer seams and feed best once the afternoon sun takes the chill off. Early mornings on small, cold water like the 49°F creek reading will likely be slow until it warms a few degrees.

The new moon means dark nights and a limited moonlight effect on feeding, so plan around dawn and dusk light rather than lunar timing. Stable flows at the two larger gauges suggest no major change over the next two to three days unless rain arrives, so check the gauges again before you leave.

For anglers targeting trout, WDFW publishes fishing and stocking reports, so check WA WDFW Fishing Reports for current stocking and creel information before choosing a water. Check state regs before harvesting.

Context

Mid-October in the eastern Washington interior is typically a transition period. Water temperatures are dropping out of the summer stress range, which usually improves trout activity in rivers, while hatches thin out and fish key more on streamers and nymphs. Brown Trout and Brook Trout generally become more aggressive as spawning approaches, so be careful to avoid wading across redds in gravel runs. Steelhead interest typically builds through the fall and into November.
