Idaho Fish and Game’s Magic Valley Region has issued an emergency order allowing unrestricted fishing in two waterways beginning July 5, 2026, as the agency prepares to close gates at Magic Dam in response to below-normal snowpack conditions.
The gate closure will substantially reduce or completely stop water flow in the Big Wood River approximately 1.25 miles below the dam and in the Richfield Canal, creating conditions that threaten fish populations in those stretches. To protect aquatic life before the water disappears, Idaho Fish and Game Commission ordered the removal of all bag and possession limits in designated salvage areas through October 1.
Salvage Areas and Restrictions
The emergency salvage order applies to two main sections. In the Big Wood River, fishing is permitted from the railroad trestle—approximately 1.25 miles downstream of Magic Dam—to the State Highway 75 Bridge. The immediate reach below the dam to the railroad trestle is excluded from the salvage order because springs in that section continue to support fish populations even when surface flows cease.
The Richfield Canal salvage zone extends from the upstream diversion point on the Big Wood River to its confluence with the Little Wood River near Richfield. Notably, portions of the canal cross private property, and anglers must obtain written permission from landowners before accessing those sections.
Anglers participating in the salvage effort must carry a valid 2026 Idaho fishing license. Fish may be taken by rod and reel, net, trap, or other conventional methods, but firearms, explosives, chemicals, and electric current are prohibited throughout the salvage period.
Water Management Context
The closure stems from the region’s below-normal snowpack conditions this year. Magic Dam’s operators have determined that available storage capacity is being fully utilized to meet downstream water delivery obligations. Once gates close on July 5, the dam will no longer release water beyond what is necessary for essential uses, leaving downstream sections of river and canal vulnerable to de-watering.
Idaho’s irrigation infrastructure relies on precise water management throughout the season. North Side Canal Co. reported maintaining an 80% water delivery target through the 2026 irrigation season despite similar constraints facing the region’s water supplies. Magic Dam operations play a critical role in maintaining that balance across Twin Falls County and surrounding areas.
Residents and anglers with questions about the salvage order or access to specific sections of the affected waterways should contact Idaho Fish and Game’s Magic Valley Regional Office at (208) 324-4359.
What Comes Next
The salvage order remains in effect through October 1, 2026, providing a three-month window for anglers to help remove fish from waters that will soon be too shallow to support aquatic life. As Twin Falls County marked America’s 250th birthday with community celebrations, the region continues managing the practical realities of water availability in the high desert. Anglers interested in participating in the salvage effort should review all regulations before fishing and respect private property boundaries on the Richfield Canal.
