Lake Trout in Idaho:
Idaho lake trout fishing isn’t where most angler’s minds go when they think of the Gem State. That’s where they would be wrong. In the picturesque landscapes of Idaho, the pursuit of lake trout is a unique and rewarding fishing experience.
While these elusive freshwater giants may not be as widespread as some other species, their presence in select Idaho waters adds an air of excitement to fishing them.
In this article, we embark on a journey to explore lake trout fishing in Idaho. We will get into the specific waters that harbor these prized catches, tactics and techniques, and I will teach you everything you need to know for a successful lake trout fishing adventure in the Gem state.
Lake Trout (Salvelinus namaycush):
In this section I will cover everything from lake trout identification, to habitat and feeding patterns, to life cycle.
Lake Trout Taxonomy and Identification:
Lake trout are a char. They are scientifically known as Salvelinus namaycush and belong to the salmonid family. This family includes salmon, trout, and char. With a scientific classification that places them within the genus Salvelinus, lake trout share their lineage with other char species such as the brook trout and bull trout.
These cold-water species are known for their distinctive appearance, featuring a streamlined body, and deeply forked tail. From a color stand point they have small creamy/yellowish irregularly shaped spots on a silvery body. Their pelvic, anal, and pectoral fins often have a leading white edge.
Both males and females have similar appearances. The best way to tell a male from a female is that they often have a longer pointier snout. What sets lake trout apart from other chars is that brook trout, bull trout, and dolly varden often have pink spots while almost all lakers do not.
Lake Trout Habitat and Distribution:
Lake trout are predominantly inhabitants of cold, deep freshwater bodies. Their presence in Idaho’s waters adds a unique dimension to the state’s varied fishing scene. These trout thrive in clear, well-oxygenated lakes, often favoring depths well beyond the reach of warmer surface temperatures. This means successful populations can only be found in select waters in Idaho.
Lake Trout Behavior and Feeding Patterns:
Lake trout are not schooling fish. Having said that like all trout and salmonids they congregate in ideal conditions. This means that where you catch one laker you are likely to catch others.
They are in constant pursuit of optimal temperatures and food sources. These fish may traverse significant distances within their preferred waters.
As carnivorous predators, lake trout exhibit a voracious appetite, preying on smaller fish, crustaceans, and even other trout. This is one of the reason’s fishery managers always seem to be making efforts to cull the populations from certain bodies of water. For example, Stanley Lake in the Sawtooth’s used to have a strong breeding population but Idaho Fish and Game is eradicating them and replacing them with sterile fish to keep the population under control.
Understanding their feeding habits and preferred prey is key for anglers seeking to entice these elusive giants with effective bait and lures. If you need help figuring out what bait to use check out our article on the best trout baits.
Now let’s take a closer look at reproduction and life cycle.
Lake Trout Reproduction and Life Cycle:
Lake trout typically spawn in shallow, rocky areas during the fall or early winter. Female lake trout create depressions in the substrate with their tails where they deposit their eggs, and males subsequently fertilize them.
The fertilized eggs adhere to the substrate, undergoing a period of incubation before hatching into fry. Young lake trout often exhibit rapid growth, maturing into the formidable predators quickly compared to some other trout species.
In this overview, we’ve just scratched the surface of the fascinating world of lake trout. We explored their taxonomy, habitat preferences, behavior, and life cycle.
Next, we will look at their history.
The History of Lake Trout:
The history of lake trout in North America is a story worth knowing and one that will enhance your appreciation of this fish.
Origins and Native Range:
Native to North America, lake trout have a longstanding presence in the continent’s freshwater ecosystems. Their historical range encompasses a vast expanse, from the northern reaches of Canada down to the northeastern United States.
Over the centuries, these cold-water loving fish have left their mark on the landscapes they inhabit, becoming an integral part of the ecological tapestry.
Indigenous Connections:
For indigenous peoples across the regions where lake trout were native, these fish held cultural significance and played a vital role in sustenance. Many Native American tribes developed intricate fishing methods and ceremonies centered around lake trout, acknowledging their importance as a valuable resource.
European Exploration:
With the arrival of European settlers and explorers, the significance of lake trout extended beyond indigenous communities. Early European colonists recognized the abundance of these cold-water species and the potential they held for commercial fishing. This led to the establishment of fisheries and a surge in demand for lake trout as a valuable food source.
Over fishing and habitat alterations caused a decline in lake trout populations, prompting conservation efforts to ensure the sustainability of these iconic fish.
Conservation and Restoration Efforts:
The 20th century witnessed a growing awareness of the importance of preserving natural ecosystems and the species that inhabit them. Conservation initiatives aimed at protecting lake trout populations gained momentum, including stocking programs, habitat restoration, and regulations to manage fishing pressure. These efforts sought to strike a balance between human enjoyment of angling and the conservation of lake trout populations, ensuring their continued existence for future generations.
Angling Evolution:
As recreational fishing gained popularity, so did the pursuit of lake trout. Anglers began to appreciate not only the challenge of catching these elusive fish but also the breathtaking beauty of the landscapes where they reside. The history of lake trout fishing evolved from a commercial endeavor to a cherished recreational activity.
In recounting the history of lake trout, we have unraveled a story of indigenous cultures, European exploration, conservation, and their adoption as a celebrated game fish.
Now let’s dig into where you can actually catch lake trout in Idaho.

Understanding the unique characteristics of each water body and tailoring fishing techniques accordingly can significantly enhance your chances of a successful and enjoyable angling experience. Now let’s look at how to actually fish for lake trout.
Fishing for Lake Trout:
I have found the below tactics and techniques work best and will help get more lakers on the line and into the boat.
Trolling with Downriggers:
Trolling is a popular and productive method for targeting lake trout, especially in the vast expanses of deep lakes. Downriggers allow you to precisely control the depth of your lures, reaching the desired levels where trophy lake trout often cruise.
Attach large spoons, jointed Rapala’s, or swim baits to your downrigger lines. These lures mimic the prey lake trout feed upon and trigger their predatory instincts. Vary trolling speeds to find the optimal pace that is triggering strikes. I have found this can be different on different days.
Vertical Jigging:
Vertical jigging is an effective technique, particularly when fishing near underwater structures, drop-offs, and points where lake trout often gather to feed. Jigging is highly effective because lake trout are often enticed by the erratic movement of the bait.
Use heavy tube jigs, spoons, or other lures that imitate bait fish. Cast towards submerged structures and let the lure sink to the desired depth before employing a rhythmic or erratic jigging motion. You can also just drop your bait over the side of the boat and let it sink before jigging.
Drifting with Live Bait:
Drifting with live bait, such as minnows, yellow perch, or even night crawlers, can be a highly productive method for enticing lake trout. This technique is particularly effective in areas where lake trout are known to patrol for prey.
Rig live bait on a slip sinker rig and allow it to drift naturally in the current. Adjust the depth of your bait based on the location of lake trout in the water column.

Ice Fishing Techniques:
In waters that freeze over Ice fishing for lake trout is a popular winter pursuit. Successful ice fishing requires specific techniques tailored to the colder conditions.
For lake trout I prefer using jigging rods but if you are using live bait, you can use tip-ups. Drill holes strategically in areas with varying depths and structure.
While it can be expensive if you are serious about ice fishing, I recommend buying a flasher fish finder. Pay attention to your electronics to locate schools of lake trout beneath the ice. You will at least know you are wasting time on a fish desert that way.
Understanding Seasonal Patterns:
Lake trout behavior varies with the seasons, influencing their preferred depths and locations in the lake. Understanding these patterns enhances the effectiveness of your fishing tactics.
In spring and fall, lake trout may move to shallower waters for spawning or feeding. During summer, they often seek cooler depths. Keep this in mind and adjust your tactics based on their seasonal movements.
Experimenting with Lure Colors and Sizes:
Lake trout can be selective about lure colors and sizes, requiring anglers to experiment and adapt to changing conditions. I recommend carrying a variety of lures including different colors and sizes in your tackle box. If one color or size isn’t producing results, be willing to switch until you find the combination that entices lake trout on a particular day.
Using Fish Finders and Electronics:
While I try to avoid electronics most of the time, modern fish finders and electronic devices are invaluable tools for locating lake trout and kokanee in vast and deep waters.
Utilize fish finders to identify underwater structures, thermoclines, and schools of fish. Adjust your fishing approach based on the information provided by these electronic aids.
Lake trout fishing requires a combination of skill, knowledge, and adaptability, and mastering these tactics will elevate your chances of catching one of these majestic freshwater predators.
Now I’ll give some tips I have picked up over the years.
Lake Trout Fishing Tips:
- I recommend using 16 – 20-pound braided fishing line with a 2-to-4-foot long fluorocarbon leader.
- Lake trout are often in deep water. We are talking 80 to 120 feet deep. I recommend attaching a drop light/line light to your line about a foot up from your lure. I have found green works the best for me.
- Tip your hook with cut bait. It can really be anything but I have found white fish, suckers, or perch works really well. The cut bait can trigger the strike, but more importantly it causes the fish to hold on just a second longer which can be the difference between a hook up and loss.
- If you are looking for a delicious meal, I recommend only harvesting lake trout pups less than 24 inches. At around 25 inches or so they really start chowing on other fish in earnest and the taste and quality of the meat goes down significantly in my opinion.
Lake Trout Size:
Lake trout (Salvelinus namaycush) are renowned for their remarkable size, making them a coveted catch among anglers seeking formidable freshwater game fish.
Impressive Lengths:
Mature lake trout are celebrated for their impressive lengths, and it’s not uncommon for these fish to exceed 36 inches or more. In some exceptional cases, lake trout have been documented reaching lengths approaching or even surpassing 40 inches. Such substantial sizes contribute to the allure of lake trout fishing. They are a true trophy fisherman’s dream.
Weighty Giants:
Beyond their length, lake trout are recognized for their substantial weight, particularly in their later years. Trophy lake trout can tip the scales at over 20 pounds, with some reaching weights exceeding 30 pounds or more.
A Colorado man caught the unofficial world record weighing in at over 73 pounds. These giants exemplify the robust growth potential of lake trout in favorable environments.
Factors Influencing Size:
Several factors contribute to the size variability among lake trout. The availability of abundant prey, such as smaller fish and crustaceans, plays a crucial role in supporting rapid growth. Additionally, the characteristics of the lake itself, including water temperature, depth, and overall ecosystem health, influence the potential size that lake trout can attain.
In the realm of freshwater angling, few fish are so prized for their trophy potential. It’s certainly one of the reasons why I chase them.
Closing the Book on Idaho Lake Trout:
Idaho, with its diverse array of lakes, reservoirs, and water bodies, offers a captivating stage for anglers pursuing the challenge of lake trout fishing. From the crystal-clear depths of Priest Lake to the serene beauty of Payette Lake, and the vast expanses of Bear Lake, each location presents an opportunity for anglers to test their skills and match their wit against these impressive fish.
As the curtain falls on this exploration, I encourage my fellow anglers to delve into the richness of Idaho’s lake trout fisheries. Whether you are a seasoned enthusiast or a novice adventurer, the allure of landing these majestic fish in an amazing environment is something that will keep you hitting the water over and over again.
Tight lines and happy fishing.
