Walleye fishery update in the Magic Valley Region

The Magic Valley Region is home to two of the state’s three managed walleye fisheries: Salmon Falls Creek Reservoir and Oakley Reservoir. In October 2025, a Fall Walleye Index Netting (FWIN) survey was conducted on Oakley Reservoir to better understand the fishery and guide management decisions. During this survey, 68% of walleye measured between 8-13 inches, 29% were between 14-20 inches, and 1% were 20 inches or larger. The largest walleye measured 29 ¼ inches, weighed 9.8 pounds, and was determined to be 19 years old. 

These results showed an increase in larger fish since the last FWIN survey in 2016, when 90% of walleye were between 8-13 inches, only 5% were between 14-20 inches, and just one fish exceeded 20 inches, measuring 21 ¾ inches and weighing 4 pounds. 

Although the survey showed an increase in larger fish compared to the previous assessment, it also revealed that walleye growth rates are slow. This slow growth is due to limited prey availability combined with an overabundance of walleye in the system, driven by both stocking and successful natural reproduction. 

As a result, walleye stocking has been paused in Oakley and Salmon Falls Creek reservoirs while biologists evaluate the extent of natural reproduction and its contribution to the population. To support this effort, surveys are planned for later this fall to sample age-0 walleye produced through natural spawning this spring in both reservoirs. The data collected will help guide adjustments to stocking strategies, with the goal of balancing walleye abundance, improving growth rates, and providing more quality fish for anglers. Additional surveys scheduled for the 2026 season include a standardized lowland lake survey at Oakley Reservoir and a FWIN survey at Salmon Falls Creek Reservoir.

As spring temperatures rise, walleye are moving into shallow waters to spawn, creating an excellent opportunity for anglers eager to get back on the water. Anglers can find success using a variety of baits and techniques. In the spring, pitching jigs tipped with soft plastics or tied with hair, along with casting crankbaits, can be especially productive. Trolling with crankbaits or using a bottom bouncer and crawler harness can be an effective approach from early season through summer.
