Bear Lake, UT

About Bear Lake

Bear Lake straddles the Utah-Idaho line in the northeast corner of Utah, a roughly 20-mile-long, high-elevation lake famous for its striking turquoise-blue water, the result of suspended calcium carbonate. At over 5,900 feet of elevation and reaching depths of around 200 feet, it is a big, cold, deep natural lake that fishes very differently from the typical Western reservoir. Anglers know it as much for its scenery as for its one-of-a-kind fishery.

What truly sets Bear Lake apart is its collection of endemic species found nowhere else on earth, including the Bonneville cisco, the Bonneville whitefish, the Bear Lake whitefish, and the Bear Lake sculpin. These native forage and gamefish, combined with a trophy Bear Lake cutthroat trout strain and stocked lake trout (mackinaw), give the lake a distinct character. The midwinter Bonneville cisco run is one of the most unusual and beloved fishing events in the Intermountain West.

Fish Species

Bear Lake supports a mix of native endemics and prized salmonids:

• Bear Lake cutthroat trout — the headline gamefish, a strain adapted to the lake that grows large by feeding on cisco and other forage. Trophy-class fish are realistic targets here.
• Lake trout (mackinaw) — stocked and well established in the deep, cold water; they can reach substantial sizes and are a popular target for deep-water anglers.
• Bonneville cisco — a small endemic whitefish-family species famous for its dense midwinter spawning run, when anglers dip-net and jig for them along rocky shorelines.
• Bonneville whitefish and Bear Lake whitefish — endemic species that provide good light-tackle action and are often caught while jigging.
• Other species — the lake also holds the small native Bear Lake sculpin (an important forage fish) and you may encounter other introduced or migratory fish, but the cutthroat, lake trout, cisco, and whitefish are the angling standouts.

Best Seasons & Times

Winter is Bear Lake's signature season. In mid-to-late winter, the Bonneville cisco run draws crowds who dip-net and jig small flies near rocky shorelines, and the cisco in turn concentrate predatory cutthroat and lake trout. When safe ice forms, hard-water anglers jig for cutthroat, lake trout, and whitefish. Always confirm ice conditions locally before walking out, as this large, deep lake does not freeze predictably.

Spring brings cutthroat closer to shore and to tributary mouths as water warms and as cutthroat move toward spawning. This is a strong window for trolling and casting in the upper water column. Summer pushes trout and lake trout deeper into cold water; downriggers, lead-core, and deep jigging become the productive approach, with low-light dawn and dusk periods best. Fall cooling brings fish back up and feeding aggressively ahead of winter, making it an excellent trolling season. Across all seasons, early morning and the last hour of light are the most reliable bites for the trout species.

Techniques & Baits

Techniques vary sharply by target species and season:

• Cutthroat trout — trolling is the mainstay. Pull spoons, minnow-imitating plugs, and flashers/dodger-and-fly setups at trout depth, going deeper and slower in summer. In spring and fall, troll the upper 30 feet and near drop-offs and shoreline structure.
• Lake trout — work deep, cold structure with downriggers and lead-core line, or vertically jig heavy spoons and tube jigs tipped with cut bait near bottom in 60-plus feet of water.
• Bonneville cisco — during the winter run, anglers use long-handled dip nets along the east-side rocky shorelines, and small jigging flies or tiny jigs also take them; cisco are commonly used (where legal) as bait for trout.
• Whitefish — small jigs, ice flies, and tiny tipped jigs fished near bottom produce well, especially through the ice.

Match your offerings to the lake's forage: cisco, sculpin, and whitefish imitations in silver, white, and natural tones are consistently effective for the predators.

Access & Launches

Bear Lake has good public access on both the Utah and Idaho sides. The Utah end of the lake includes state park facilities with developed boat-launching access, and there are additional public launch areas and shoreline access points around the lake, with marina and rental services available seasonally in the lake communities. Shore and rocky-shoreline access along the east side is especially important during the winter cisco run.

Because the lake is large, deep, and open, wind and sudden weather can build dangerous waves quickly, so check forecasts and use a seaworthy boat. Note the lake spans two states; if you fish near or across the state line, be aware that licensing and regulations differ by state. Confirm current ramp availability, marina services, and conditions locally before your trip.

Regulations & Licenses

A valid Utah fishing license is required to fish the Utah portion of Bear Lake, and because the lake also extends into Idaho, anglers fishing the Idaho side need the appropriate Idaho license; reciprocal or boundary-water rules can apply, so verify which license you need for where you intend to fish. Bear Lake has species-specific rules — including special regulations tied to the cisco run, cutthroat, and lake trout — and slot, size, and bag limits apply and can change from year to year.

Always check the current Utah Division of Wildlife Resources (and Idaho Fish and Game, if applicable) regulations before fishing for the up-to-date limits, gear restrictions, seasons, and any rules specific to the Bonneville cisco dip-netting season. Following these rules protects the lake's unique endemic species.

Frequently Asked Questions

What fish is Bear Lake, Utah best known for?
Bear Lake is best known for its endemic Bonneville cisco and the trophy Bear Lake cutthroat trout, along with stocked lake trout (mackinaw) and native whitefish. The cisco, found nowhere else on earth, draws anglers for its famous midwinter spawning run.

When is the Bonneville cisco run at Bear Lake?
The Bonneville cisco run happens in the middle of winter, typically in January, when large numbers of cisco move into rocky shoreline areas to spawn. Anglers use long-handled dip nets and small jigs to catch them, and the run also concentrates predatory trout nearby. Confirm timing and any special regulations locally each year.

How do you catch lake trout at Bear Lake?
Target lake trout in deep, cold water using downriggers or lead-core line to troll spoons and plugs near bottom, or vertically jig heavy spoons and tube jigs tipped with cut bait in 60-plus feet of water. Dawn, dusk, and the cold-water seasons of fall through spring are the most productive.

Do I need a special license to fish Bear Lake since it's on two states?
You need a valid Utah fishing license for the Utah side and an Idaho license for the Idaho side, since Bear Lake straddles the state line. Boundary-water or reciprocal rules may apply depending on where you fish, so always check current Utah DWR and Idaho Fish and Game regulations before your trip.
