Eastern WA trout and smallmouth settle into fall pattern
Cool, steady water defines the Eastern WA freshwater scene this week. The USGS gauge 12462500 reads 461 cfs at 50°F, while gauge 12492900 shows 48°F with very low flow at 1.89 cfs. Gauge 12484500 reports 883 cfs with no temperature reading. Water in the upper 40s to 50 is comfortable for Rainbow Trout and Brown Trout, which tend to feed more actively as the water cools. Smallmouth Bass typically slow in this range and sit tight to rocky structure. Tactical Bassin (blog) is pushing fall jig fishing, noting that fish position near hard structure like rocks and laydowns, a pattern that translates to Eastern WA smallmouth water.

With a New Moon today, expect low light penetration at night and a strong feeding drive at first and last light over the coming days. Water temperatures in the upper 40s should hold or drift lower if nights stay cold, so plan around the warmest part of the afternoon for Smallmouth Bass, when a slow jig or soft jerkbait is most likely to draw a bite. Trout should be more willing early and late, and slower, deeper runs near current seams are worth a look.
Flows at gauge 12462500 are moderate at 461 cfs, a manageable range for wading. Gauge 12484500 at 883 cfs suggests a bigger, pushier stretch where you will want to fish edges and softer water. The very low flow at gauge 12492900 means a small stream, so approach quietly and keep casts short.

Context
Mid October in Eastern WA typically marks the transition from summer low-flow patterns to the cooler, more settled fall season. Trout generally become more active as water temperatures drop out of the 50s, and fall is a classic time for Brown Trout to feed more aggressively ahead of the spawn. Smallmouth usually begin sliding toward deeper, slower water as temperatures keep falling, so the best bites compress into the warmest hours of the day. Check state regulations for seasons, closures, and limits before harvesting.
