What You'll Find at Smith Lake

Smith Lake sits in the Idaho Panhandle near Bonners Ferry, a small mountain reservoir that holds native cutthroat trout and brook trout in cold, clear water. The lake runs roughly 40 acres and sits at elevation, so water temperatures stay cool even in summer. The shoreline is mostly forested, with some rocky banks and shallow bays where trout feed. Access is straightforward — a maintained road brings you to a public boat launch and parking area on the north end.

This is not a destination lake for trophy fish, but it is reliable for steady action if you know what to throw. Cutthroat here run 8 to 14 inches mostly, with occasional fish pushing 16 inches. Brook trout are smaller on average but more aggressive. The lake is shallow enough that you can wade from shore in many spots, and the water clarity means you can sight-fish if you arrive early or stay late.

Key Takeaways

  • Smith Lake holds native cutthroat and brook trout in cold mountain water, with fish averaging 8 to 14 inches and best action in early morning and evening.
  • A public boat launch and parking area sit on the north shore, and the lake is shallow enough to wade from shore in many locations.
  • Cutthroat respond well to small spinners and soft plastics; brook trout will take almost anything small and moving, especially near structure.
  • The lake sits at elevation, so water stays cold year-round, but access can be limited by snow in winter and early spring.
  • No motorboat restrictions exist, but the small size and shallow water mean trolling is less effective than casting from shore or a small boat.

When to Fish Smith Lake

Spring and early summer, from late April through June, is when Smith Lake fishes best. Snowmelt keeps water cool and oxygenated, and trout are actively feeding after winter. The lake typically opens to fishing around the time the road becomes passable — usually late April, though this varies by year depending on snow depth. Call the Idaho Department of Fish and Game regional office in Coeur d'Alene to confirm current conditions before you drive up.

Summer fishing slows as water warms, but early morning and late evening remain productive. Fall, from September through October, brings another strong bite as water cools again and trout feed heavily before winter. Winter access is unreliable — the road can close after heavy snow, and ice fishing is possible but not common here. Most anglers focus on spring through fall, when conditions are most predictable and the road stays open.

Tackle and Technique for Cutthroat and Brook Trout

Cutthroat trout at Smith Lake respond to small spinners in sizes 0 and 1, especially in silver, gold, and copper finishes. Cast from shore or a small boat and retrieve steadily, letting the blade flash in the clear water. Soft plastics work too — 2-inch minnow imitations in white, pearl, or natural colors fished on a 1/16-ounce jig head will take fish consistently. Work the edges of weed beds and rocky structure where trout hold.

Brook trout are less selective. They will chase small spinners, but they also respond to wet flies, small streamers, and even tiny crankbaits. If you are fly fishing, bring a 4-weight or 5-weight rod and small nymphs in black, brown, and olive. Strip them slowly near the bottom in deeper water, or fish dries in the early morning if you see rises. The shallow bays on the west and south shores often hold brook trout in the shallows, especially in spring.

Wading is effective here because the lake bottom is mostly silt and sand with scattered rocks. Wade out 20 to 30 feet from shore and cast parallel to the shoreline or toward any visible structure. The water clarity means trout can see you, so move slowly and avoid casting shadows across the water.

Access and Facilities

The public boat launch is located on the north shore and includes a gravel parking area with room for several vehicles and trailers. The launch itself is a concrete ramp in good condition, suitable for small boats and canoes. There is no developed campground at the lake, but dispersed camping is available on nearby Forest Service land — check with the Bonners Ferry Ranger District for current rules and conditions.

The nearest services are in Bonners Ferry, about 15 miles south, where you will find gas, food, and lodging. Bring water and supplies with you, as there are no facilities at the lake itself. The road to Smith Lake is paved and maintained year-round, but winter snow can close it temporarily. Cell service is spotty, so do not rely on your phone for navigation or emergencies.

Regulations and What to Know Before You Go

Smith Lake follows standard Idaho fishing regulations. You will need a valid Idaho fishing license, which you can purchase online through the Idaho Department of Fish and Game website or at any sporting goods store in Bonners Ferry. Check the current regulations for cutthroat and brook trout — daily catch limits and size restrictions can change, and some waters have special rules for native cutthroat.

The lake is open year-round to fishing, but practical access is limited to late spring through fall. No motorboat restrictions apply, but the small size means most anglers fish from shore or use small boats and canoes. Respect private property at the south end of the lake — some shoreline is privately owned, and access is limited to the public launch and immediate surrounding area.

Similar Waters Near Bonners Ferry

If Smith Lake is crowded or you want to explore other options, several similar mountain lakes sit within 30 minutes of Bonners Ferry. Priest Lake, to the east, is larger and holds kokanee salmon along with cutthroat and brook trout. Pend Oreille, the big water to the south, offers more variety but requires more planning and different tackle.

For smaller, quieter water similar to Smith Lake, ask locals in Bonners Ferry about access to other Forest Service lakes — many are less known and see fewer anglers. The Bonners Ferry Ranger District office can point you toward options that match what you found at Smith Lake, whether you are looking for more cutthroat, easier wading, or simply fewer people on the water.

Frequently Asked Questions

Can I fish Smith Lake in winter?

Technically yes, but access is unreliable. The road can close after heavy snow, and ice fishing is not common here. Spring through fall is when most anglers fish this lake. Call ahead to confirm the road is open before making the drive.

Do I need a boat to fish Smith Lake?

No. The lake is shallow and small enough that wading from shore is productive. A small boat or canoe gives you more water to cover, but many anglers catch fish without one by working the shoreline and bays.

What is the best time of day to fish here?

Early morning and late evening are most productive, especially in summer when water warms during the day. Spring and fall, the water stays cool longer, so fishing can be good throughout the day.

Are there any size restrictions on cutthroat at Smith Lake?

Check the current Idaho fishing regulations before you go — rules change and can vary by water. The Idaho Department of Fish and Game website has the most current information, or call the Coeur d'Alene regional office.

What should I bring that I might forget?

Bring water and snacks — there are no facilities at the lake. Sunscreen and a hat are essential at elevation, where sun exposure is intense. A headlamp or flashlight is useful if you plan to fish early morning or evening.
