Located just outside Coeur d’Alene, Idaho, Fernan Lake is a beautiful and tranquil natural oasis, perfect for outdoor enthusiasts.
Fernan Lake in North Idaho offers year-round fishing and easy access for both boaters and shore anglers. Two public boat launches make getting on the water simple, with a 24-hour east ramp convenient for overnight trips and a west ramp near the freeway ideal for quick kayak launches. The shoreline has plenty of space for bank fishing, and the lake retains a peaceful, away-from-it-all feel despite being just minutes from downtown.
Rainbow Trout
Rainbow Trout are stocked in Fernan Lake multiple times a year and are a top target species year-round. Trolling with corn or worms behind a dodger is one of the most effective ways to catch them, especially from a kayak or boat. Shore anglers often do well using sliding sinker rigs with PowerBait or trout marshmallows. In the summer months, trout move into deeper, cooler water and are best targeted by trolling. During late fall and winter, they come into the shallows and become much easier to catch from shore, particularly around the bays.
- Fish early or late – Trout bite best at dawn and dusk, especially in low-light conditions.
- Troll deep in summer – Use a dodger and short leader with corn or a worm when trout move to cooler depths.
- Use the right bait from shore – PowerBait or marshmallows on a sliding rig work great in the shallows during spring, fall, and winter.
- Follow the stocking schedule – Fishing tends to heat up shortly after each stocking, so time your trips accordingly.
Bass
Largemouth and Smallmouth Bass are both popular and prevalent during the warmer months. Spring and summer offer the best action, especially when the weather heats up. They respond well to a wide range of baits and lures, including crankbaits, jigs, soft plastics, spinnerbaits, and even live worms at times.
- Target warm, shallow water – In spring and summer, bass cruise the shallows near structure like docks, brush, and weed lines.
- Match the hatch – Use soft plastics, crankbaits, or jigs that mimic crawfish or baitfish—especially in natural colors.
- Fish early morning or evening – Bass are most active during low-light hours when water temps are ideal.
- Slow it down on hot days – When the sun’s high, work your baits slower and deeper near cover or drop-offs.
Channel Catfish
Channel Catfish are stocked once a year and remain catchable all summer long. Most average over three pounds and can be caught by bottom fishing with strong-scented baits. Target deeper water during the day and shallower areas after dark for the best results.
- Fish at night or early morning – Catfish feed most actively during low-light hours and overnight.
- Bottom fish in deeper water by day – During the day, target deeper holes with strong-scented baits.
- Move shallow after dark – At night, catfish move into the shallows to feed—focus on flats, bays, or shoreline drop-offs.
- Use smelly baits – Stink bait, cut bait, or even marshmallows soaked in scent can draw in cruising catfish.
Northern Pike
Northern Pike can grow to impressive sizes in Fernan Lake. The largest I’ve personally seen this year was over 11 pounds. They’re typically caught on crankbaits, spoons, large swimbaits, or dead baits fished slowly in the shallows or around weed lines. As soon as the ice melts, these things are on fire!
Tips for Success!
- Target weed edges and shallow bays – Pike often ambush prey along weed lines, especially in spring and early summer.
- Use flashy, aggressive lures – Crankbaits, spoons, spinnerbaits, and large swimbaits trigger reaction strikes.
- Fish during cooler parts of the day – Early morning and late evening offer the best chance for active pike.
- Go big for big bites – Don’t be afraid to throw larger lures or dead bait when targeting trophy-sized fish.
Yellow Perch
Yellow perch are available year-round in Fernan Lake and are most active in the warmer months. Most average 8–10 inches and are often caught in schools, providing steady action. They bite well on worms, small jigs, and soft plastics, especially near weed edges, docks, and drop-offs. Target slightly deeper water during the day and move shallower in the morning or evening for the best results.
- Fish early morning or late afternoon – Perch feed most aggressively during low-light periods.
- Target schools near weed edges – Look for vegetation close to drop-offs where perch often congregate.
- Downsize your tackle – Small jigs, soft plastics, or bits of worm work best for their smaller mouths.
- Adjust depth with the sun – Fish deeper during bright midday hours and move shallower when light levels drop.
Crappie
Crappie are a less common but welcome catch in Fernan Lake, showing up most often in the warmer months and especially in spring as the water temperature rises. They tend to school in the back end of the lake and feed actively during the morning hours. Small jigs tipped with soft plastics or minnows work best, especially when fished near submerged structure, docks, or along weed edges. While not as abundant as perch or bass, when you find a school, the action can be steady and rewarding.
Tips for Success!
- Fish early in the morning for the most consistent crappie action.
- Focus on the back end of the lake where crappie tend to school.
- Use small jigs with soft plastics or minnows for best results.
- Target submerged structure, docks, and weed edges to locate active fish.
Bullhead Catfish
Bullhead catfish are plentiful in Fernan Lake and bite readily from spring through early fall. They aren’t stocked like channel catfish but have established a strong, self-sustaining population. Most range from 1 to 2 pounds, though larger fish are possible. Bullheads feed aggressively in low-light conditions, making evening and nighttime fishing especially productive. Simple rigs with worms, cut bait, or chicken liver fished on the bottom will draw steady bites, and they can often be found in the same areas as channel catfish, especially in shallower flats and bays after dark.
- Fish in the evening or at night when bullheads are most active.
- Target shallower flats and bays after dark for the best results.
- Use worms, cut bait, or chicken liver on a simple bottom rig.
- Expect steady action from fish averaging 1–2 pounds.
Fernan Lake Access
Fernan Lake has two boat launches, plenty of bank fishing and one camping area that is accessible by boat.
East Fernan Lake Road on the north side of the lake offers plenty of bank fishing, just pull over in one of the many shoulder parking areas. Although some spots can be a bit steep and rocky to get down to the water, but there is plenty of cover for fish.
The West Boat Ramp is the main boat launch, near the freeway. If features multiple fishing docks, a small park, and a handicap accessible restroom. This area also has plenty of parking but can get busy during the summer months.
The East Boat Ramp is more remote and less used, with limited parking and just one small dock. It can get a bit overrun by lily pads for motorboats. It’s open 24 hours and does have a handicap accessible bathroom. Another nice thing is that it is right across the lake from the only legal campsite.
The boat-in campsite is pretty primitive and only accessible by boat. It doesn’t have bathroom facilities and can get a bit overgrown, but it usually accommodates a couple of small tents and a fire pit or two. It’s important to note that the western parking lot closes at 10:00pm, so be sure to park East Boat Ramp if you plan to stay overnight.
Easy drive from Coeur D’ Alene!
If you live in the Coeur d’Alene area, Fernan Lake is one of the quickest and easiest fishing spots to reach, just minutes from downtown. With a paved boat launch, parking, and public access along the north shore, it offers a convenient option for spontaneous trips.
