What to expect at Fernan Lake

Fernan Lake sits in the Coeur d'Alene National Forest near Coeur d'Alene, Idaho, at roughly 2,300 feet elevation. The lake covers about 90 acres and holds kokanee salmon and rainbow trout as the primary species. The water is clear and cold, typical of mountain lakes in the region, and the shoreline is forested with ponderosa pine and Douglas fir.

The lake is accessible by a short drive from Coeur d'Alene — roughly 20 minutes northeast on Highway 95, then Forest Road 9 — making it a practical half-day or full-day destination. The setting is quieter than the larger lakes in the region, with fewer motorboats and a more intimate feel. Camping and day-use facilities are available nearby, though the lake itself has limited developed infrastructure on the water.

Key Takeaways

  • Fernan Lake holds kokanee salmon and rainbow trout, with kokanee being the primary draw during their spawning season in late summer and fall.
  • Access is by vehicle to a parking area, then a short walk to the water; no boat launch exists, so fishing is from shore or by canoe and kayak.
  • Idaho fishing regulations require a valid fishing license, and kokanee have specific season dates and daily catch limits that change year to year.
  • The lake is open year-round, but kokanee fishing peaks from August through October when the fish move into shallower water to spawn.
  • Nearby Forest Service campgrounds and day-use areas provide parking and facilities, though services are basic and the area fills quickly on weekends.

Seasons and what fish are active when

Kokanee are the signature fish at Fernan Lake and drive most of the fishing pressure. These landlocked salmon spawn in late summer and fall, typically from August through October. During this window, kokanee move into shallower water and become catchable from shore. Their spawning colors — bright red bodies and dark heads — make them visually distinctive and exciting to pursue. Early morning and late evening are most productive, as the fish are more active in cooler water.

Rainbow trout are present year-round but are secondary to kokanee in terms of angler focus. They are most active in spring (April through June) and again in fall after the water cools. Winter fishing is possible but slow; the lake does not freeze solid most years, though ice can form along the edges. Summer is the slowest season overall, as the water warms and both species move deeper.

How to fish from shore and what gear works

Fernan Lake has no boat launch, so shore fishing and small watercraft (canoe, kayak, float tube) are the primary methods. Shore anglers can walk the perimeter in most places, though some sections are steep or brushy. The best access points are near the parking areas and day-use zones on the north and west sides of the lake.

For kokanee, small spinners (size 0 to 2), spoons, and jigging with small soft plastics or maggots work well. Kokanee have small mouths, so downsizing tackle is important. A light spinning rod (5 to 6 feet) with 4- to 6-pound test line is standard. For rainbow trout, similar gear works, though slightly larger spinners and spoons are acceptable. Fly fishing is possible but less common; small nymphs and streamers in sizes 12 to 16 are effective if you have the skill to cast from rocky or brushy shore.

Jigging is particularly effective for kokanee in deeper water near the center of the lake if you are fishing from a kayak or float tube. A vertical presentation with a small jig or spoon tipped with maggot or a small soft plastic can produce steady action during the spawn.

Idaho fishing license and regulations

You must have a valid Idaho fishing license to fish Fernan Lake. Licenses are sold online through the Idaho Department of Fish and Game website, at sporting goods retailers, and at some gas stations and convenience stores in the Coeur d'Alene area. A one-day license is available if you are visiting briefly; annual licenses are cheaper if you plan multiple trips.

Kokanee and rainbow trout have separate regulations. Kokanee season dates, daily catch limits, and size restrictions change annually and are published in the Idaho Sport Fishing Seasons and Rules booklet. As of recent years, kokanee have had a daily limit of 5 fish with no size restriction, but this varies. Rainbow trout typically have a limit of 5 fish as well, though some waters have different rules. Check the current regulations before you go — the rules booklet is free and available online or at license vendors.

Bait restrictions may apply; some waters allow live bait, others do not. Fernan Lake generally allows bait, but confirm the current rules. Catch-and-release is always allowed, and barbless hooks are not required but are encouraged for fish welfare.

Getting there and where to stay

Fernan Lake is accessed via Highway 95 north from Coeur d'Alene. Turn east on Forest Road 9 (also called Fernan Lake Road) and follow it to the lake. The drive is paved and well-marked. Parking is available at a small lot near the lake; during peak season (August through October), arrive early on weekends as the lot fills quickly.

The nearest lodging is in Coeur d'Alene, about 20 minutes away, with hotels, motels, and vacation rentals throughout the city. For camping, the Coeur d'Alene National Forest has several campgrounds within 30 minutes of Fernan Lake. Fernan Lake itself has no on-site campground, but nearby options include Blackwell Lake Campground and other Forest Service sites. Facilities at these campgrounds are basic — vault toilets, no hookups — and they fill on summer weekends.

Coeur d'Alene has full services: grocery stores, gas, restaurants, and tackle shops. The town is a good base if you plan to fish multiple lakes in the region or want reliable lodging and meals.

What makes Fernan Lake different from other Coeur d'Alene area lakes

Fernan Lake is smaller and quieter than Coeur d'Alene Lake itself, which is much larger and busier with motorboats and recreation. Fernan is better suited to anglers seeking a more peaceful setting and willing to fish from shore or a small, quiet watercraft. The kokanee spawn is more predictable and concentrated here than on larger lakes, making it a reliable destination during late summer and fall.

Priest Lake and Pend Oreille Lake, also in the region, are larger and have more developed boat access and facilities. Fernan Lake appeals to anglers without boats or those who prefer a more intimate, less crowded experience. The trade-off is fewer services and a shorter peak season.
