About Bull Lake, Montana

Location and Geography

Bull Lake is located in northwestern Montana’s Lincoln County, approximately 15 miles south of Troy and 25 miles southwest of Libby. Nestled in a valley between the Cabinet Mountains to the east and the Bitterroot Range to the west, this natural glacial lake stretches about 5 miles long and is just over a mile wide at its widest point. The lake’s setting among dense pine forests and dramatic mountain peaks creates a postcard-perfect Montana landscape that changes character with each season.

Lake Characteristics

Bull Lake covers approximately 1,200 acres, with a maximum depth of about 180 feet near its center. The lake features several bays and inlets, particularly along its western shoreline, creating protected areas perfect for paddleboarding and fishing. Several small islands dot the southern portion of the lake, creating interesting exploration opportunities for paddlers and boaters alike.

Best Seasons for Water Activities

While Bull Lake is accessible year-round, the prime season for water activities runs from late May through mid-October. June through August offers the warmest water temperatures and air temperatures consistently in the 70s and 80s Fahrenheit, ideal for swimming and paddleboarding.

Early summer (late May through June) often provides the clearest water visibility, sometimes exceeding 20 feet. Fall brings spectacular foliage colors to the surrounding forests, typically peaking in late September to early October, offering tranquil paddleboarding experiences with fewer visitors.

Weather Patterns and Water Conditions

Bull Lake’s mountain valley location creates some distinctive weather patterns. Mornings typically offer the calmest water conditions, with glassy surfaces ideal for paddleboarding and photography. As the day progresses, afternoon breezes often develop, particularly in summer months.

Summer thunderstorms can develop quickly, especially in July and August. Water temperatures range from the mid-40s°F in early spring to the upper 60s°F in late summer, so appropriate safety precautions should always be taken.
