Snake River steelhead run tracks toward record lows

What's biting

What's next

Expect flows to hold in this range through the week, with water temps easing gradually as overnight lows drop into late September, a typical seasonal drift for the region. The First Quarter moon favors shorter, more predictable feeding windows around dawn and dusk rather than an all-night bite, so plan trips around first and last light.

Given the record-low steelhead numbers Hatch Magazine is reporting, anglers targeting that run should check current state harvest rules before keeping fish and temper expectations on encounter rates through the fall push. The warmer 67°F gauge is worth watching too — if that tributary keeps running above the mainstem's 58°F, it could hold fish differently than the colder water through the transition.

Context

Late September on the Snake and Salmon system typically marks the shift from summer patterns into the fall steelhead push, with migration building through October. A run this far below historical counts by mid-September is an early signal worth watching rather than a one-week blip, since the count has been running since July 1. Water in the high 50s to upper 60s is within the normal range for this stretch of the calendar in freshwater systems at this latitude and elevation.
