Fishing Bull Lake Montana: Expert Guide & Secret Spots

There’s something magical about the first light of dawn breaking over Bull Lake, Montana—the mist rising from the surface as you cast your line into the glass-like stillness. For those who love fishing, Bull Lake Montana offers a rare combination of beauty, solitude, and rich angling opportunities. Despite its impressive size and abundance of fish, it remains blissfully uncrowded compared to the state’s more famous fishing destinations.

The Shangrilog, A Bull Lake Cabin makes for the perfect basecamp. Perched right on the eastern shore, it provides immediate lake access and has become my second home in pursuit of the lake’s diverse and thriving fish population.

Bull Lake Montana’s Rich Aquatic Ecosystem

Native and Stocked Fish Species in Bull Lake

Bull Lake hosts an impressive variety of fish species that keep anglers coming back season after season. The lake is primarily known for its excellent lake trout (Mackinaw) fishing, with specimens regularly reaching 10-20 pounds and occasional trophy catches exceeding 30 pounds.

The smallmouth bass population has been flourishing in recent years, with 2-3 pound fish common and some reaching up to 5 pounds. Northern pike provide thrilling action, especially in the shallower north end, with fish up to 20 pounds not uncommon.

Other species worth targeting include:

Kokanee salmon (especially in late summer)
Rainbow trout (primarily in the creek mouths)
Bull trout (catch and release only)
Yellow perch (abundant but smaller sized)
Mountain whitefish (often caught while targeting other species)

Understanding Bull Lake’s Underwater Topography

Bull Lake’s unique bathymetry creates perfect habitat zones for different species throughout the year. The lake reaches depths of over 220 feet in the southern basin, providing ideal cold-water habitat for lake trout and kokanee salmon.

The north end features extensive shallow flats ranging from 5-15 feet deep, with scattered weed beds that northern pike and smallmouth bass call home. Multiple underwater points and humps rise from the depths along both shorelines, creating prime feeding stations where predator fish ambush their prey.

The most productive spots are often where distinct habitat transitions occur – where deeper water meets shallow flats, where rocky substrate changes to muddy bottom, or where current from incoming creeks creates flow patterns. These transition zones consistently hold fish throughout the seasons.

Best Time to Fish Bull Lake Montana – Seasonal Guide

Spring Fishing at Bull Lake (April-June)

As the ice recedes in April (sometimes earlier in mild winters), Bull Lake’s fish become increasingly active. This post-winter period offers excellent opportunities as fish move into shallower water to feed after the lean winter months.

Northern pike are particularly aggressive in spring, staging in shallow bays where the water warms first. I’ve had tremendous success casting large spinnerbaits and swimbaits along emerging weed edges during this time.

May brings the lake trout into somewhat shallower water (30-60 feet) as they follow baitfish schools. Trolling with downriggers using spoons or cut bait becomes highly effective. By June, the smallmouth bass begin their spawning activities, creating exciting sight-fishing opportunities in shallow, gravelly areas.

Summer Fishing Opportunities (June-August)

Summer transforms Bull Lake into a multi-species fishing paradise, though strategies must adapt to the changing conditions. Early mornings and evenings provide prime shallow-water action for smallmouth bass and pike, while midday often requires targeting deeper-holding lake trout.

During a scorching July trip last year, I discovered a pattern of trolling at 80-100 feet during midday that consistently produced lake trout in the 5-10 pound range. When the sun began setting, switching to topwater presentations near the weed edges resulted in explosive smallmouth strikes.

August brings the kokanee salmon into play as they school before their fall spawning run. Trolling small bright-colored lures at 30-50 feet often produces limits of these delicious fish, which make for incredible eating back at Shangrilog Cabin.

Fall Fishing Prime Time (September-October)

Fall might be Bull Lake’s finest fishing season. As water temperatures cool, lake trout move shallower, often into the 20-40 foot range, while feeding aggressively before winter. Some of my largest lake trout have come during October trips using large jigging spoons worked vertically over underwater humps.

Smallmouth bass cluster around rocky structure and feed heavily on crayfish during this period. Crayfish-imitating jigs and crankbaits can produce dozens of quality fish in a single outing.

An added bonus of fall fishing is the spectacular scenery, with the surrounding forests transformed into a mosaic of red, orange, and gold. The combination of fewer anglers, hungry fish, and breathtaking views makes autumn my favorite time on Bull Lake.

Winter Ice Fishing Potential (December-March)

When safe ice forms (usually by late December), Bull Lake offers exceptional ice fishing opportunities. The lake’s yellow perch provide consistent action, while lake trout and northern pike offer trophy potential for those willing to drill multiple holes and stay mobile.

Safety is paramount during ice season. I never venture out with less than 4 inches of clear ice and always carry safety gear. The north end generally freezes first and provides the most consistent ice conditions for early-season ice anglers.

Top Fishing Locations on Bull Lake Montana

North End Hotspots

The north end of Bull Lake features extensive shallow flats interspersed with deeper channels, creating perfect habitat for northern pike and smallmouth bass. Key locations include:

Keeler Creek Mouth: This incoming creek creates current and attracts baitfish, making it a prime feeding station. The eastern side has a deeper drop-off that consistently holds fish.
North Bay Weed Edges: The expansive weed beds in the northernmost section hold impressive pike populations. Focus on the outer edges where weeds meet deeper water.
The Narrows: Where the lake constricts slightly about a mile from the north end, creating a natural funnel that concentrates fish.

South Basin Fishing Grounds

The southern portion of Bull Lake offers deeper water and different structure types:

South Basin Humps: Several underwater humps rise from 100+ feet to within 30-40 feet of the surface. These are prime lake trout locations throughout the year.
Ross Creek Inlet: This significant creek entrance creates an underwater delta with varied depths and current patterns that attract multiple species.
East Wall Drop-offs: Along the eastern shoreline (where Shangrilog Cabin is located), steep underwater cliffs drop quickly to deep water, creating perfect vertical structure for lake trout.

Creek Inlets and River Mouths

Bull Lake’s tributary creeks provide some of the most dynamic fishing areas:

Keeler Creek: As mentioned, this northern inlet attracts various species throughout the year.
Ross Creek: The largest tributary, located on the southern end, attracts rainbow trout and kokanee salmon during spawning seasons.
Copper Creek: A smaller inlet on the western shore that creates a quiet bay with fallen timber – a smallmouth bass hotspot.

Hidden Coves and Local Secrets

Some of my favorite spots on Bull Lake are less obvious but incredibly productive:

The Sunken Island: Located approximately midway down the lake’s western side, this underwater structure rises to within 15 feet of the surface but is invisible from shore. I’ve caught some of my largest lake trout here.
Cabin Point: Just north of Shangrilog Cabin, a subtle underwater point extends 100 yards into the lake, creating a natural feeding station.
South End Rock Pile: A boulder field in 10-20 feet of water that smallmouth bass find irresistible, especially in late summer and fall.

Bull Lake Montana Fishing Techniques and Tackle

Fly Fishing Success Strategies

While not traditionally known as a fly fishing destination, Bull Lake offers surprising opportunities for fly anglers. The creek mouths provide excellent rainbow trout action on standard nymphs and dry flies, while the shallow north end allows sight-casting to cruising northern pike with large streamers.

I’ve had tremendous success using 8-weight rods with sinking lines for smallmouth bass, particularly with crayfish patterns worked along rocky shorelines. During summer evenings, floating lines with popper patterns can trigger explosive strikes in the shallows.

Trolling and Deep Water Tactics

Trolling remains the most consistent method for targeting Bull Lake’s lake trout population. Downriggers are essential for precise depth control, with most productive depths ranging from 40-100 feet depending on the season and water temperature.

Effective lake trout lures include:

Silver/blue spoons (3-5 inches)
Cut bait rigs with sucker or herring
Glow-in-the-dark dodger and squid combinations
Deep-diving crankbaits in natural baitfish patterns

Jigging can be equally effective once fish are located. Dropping heavy metal jigs (1-2 ounces) and working them with an aggressive lift-fall action directly over suspended fish shown on your electronics often triggers reaction strikes from trophy lake trout.

Shore Fishing Opportunities

Don’t have a boat? Bull Lake still offers excellent shore fishing options, particularly near the public access points and along the developed eastern shoreline where Shangrilog Cabin is located.

The fishing dock near the north public access consistently produces yellow perch and smaller rainbow trout for anglers using simple worm rigs under bobbers. Casting weighted spoons or spinners from rocky points can connect you with smallmouth bass and the occasional northern pike.

For evening fishing directly from Shangrilog’s waterfront, I recommend medium-action spinning gear with 1/4 oz jigs tipped with twister tails, worked parallel to the shoreline as light fades.
