In years of low fish returns, would you limit your fishing trips to support conservation efforts?
Idaho Fish and Game has lowered daily bag limits for adipose-clipped steelhead to two fish to protect populations. This regulatory shift follows reports of total steelhead return counts that currently sit among the lowest recorded since 1938.
Why it matters
The stricter harvest limits are a direct response to significantly low fish return counts, which are estimated at less than half of the previous year's figures. Conserving current stocks is essential as officials navigate one of the most challenging migration seasons in decades.
Anglers are now limited to a daily bag of 2 adipose-clipped steelhead and a seasonal limit of 20. Recent field interviews indicate a catch rate of 64 hours per fish, while river flows near Salmon remain at 95% of the historic average.
The players
Idaho Fish and Game
This state agency is responsible for the management, protection, and preservation of fish and wildlife resources within Idaho.
The details
Biologists monitor the population using PIT tag estimates at the Bonneville Dam, identifying that roughly 90% of the current return consists of 2-ocean steelhead averaging 28 inches in length. While current returns are sparse, catch rates are projected to improve through November as fish migrate toward the Pahsimeroi and Sawtooth hatcheries.
Timeline
1938 marked the start of official steelhead counts at Bonneville Dam.
October 8, 2026, was the start date for angler interviews along the Upper Salmon River.
October 14, 2026, was the reporting date for river flow and catch data.
November 2026 is the timeframe when officials project an improvement in catch rates.
Seasonal Patterns
Current steelhead migration levels are being evaluated against the 1938 steelhead return data baseline. This year marks a significant decline, as the total return count reflects one of the poorest outcomes for the species since tracking began.
Anglers must adhere to the new daily bag limit of two adipose-clipped steelhead and the seasonal cap of 20 fish. Visitors to the Upper Salmon River should prepare for difficult fishing conditions, as current data indicates a high effort requirement of 64 hours per catch.
The takeaway
The sharp reduction in return counts necessitates caution for anglers planning trips to the Upper Salmon River this season. Prospective fishers should check official rules frequently to ensure compliance with changing harvest limits during this period of low population.
What happens next
Steelhead catch rates are expected to show improvement throughout November 2026 as more fish reach the upper river.
