History & Status of the Fishery
Bog Lake is a 249 acre body of water located approximately 11.5 miles north-northwest of Isabella, completely within the Boundary Waters Canoe Area Wilderness (BWCAW). The present access is a 0.9 mile hiking trail from a small parking area (four cars) at the north end of USFS Rd. #377D. A self registration box and day-use permits are located at the trail-head for day-trips and off-season camping. From May 1 through September 30 a quota system is in place for overnight camping in the BWCAW, requiring a reservation (fee) for travel from each entry point. All BWCAW regulations apply to Bog Lake and the access area; state-wide fishing regulations for inland waters apply to Bog Lake.
The lake has a maximum depth of 16 feet, 93% littoral, with a secchi disk reading of 7.9 feet in the brown, bog stained water. Water quality indicated the lake was very soft and infertile. Sand is the most common substrate followed by boulder, ledge rock and detritus. Spawning habitat was rated as fair for northern pike, good for yellow perch and excellent for walleye.
The fish sample in 2010 consisted of northern pike, walleye, white sucker and yellow perch. Walleye were sampled in above average numbers for northeastern Minnesota lakes with similar characteristics. The average size of walleye was small at slightly less than 0.7 pound (11.75 inches); the largest walleye was 24.4 inches. The walleye catch was similar to catches in previous population assessments, dating back to 1962, where high numbers of small walleye were also sampled. Walleye growth was slow in Bog Lake compared to fish sampled in other Finland area assessments.
Northern pike were sampled in below average numbers for the lake class. The northern pike average size was 3.5 pounds (24.5 inches); the largest northern pike was just over 32 inches. Historically, the northern pike catch has been low numbers of small fish; the average size sampled in 2010 was the largest recorded in any assessment.
Yellow perch were sampled in above average numbers of above average size in the 2010 lake survey. The average weight was 0.33 pound (8.1 inches); 52% of the yellow perch sampled were greater than 8 inches, the largest 11.4 inches. Previous investigations have also recorded high numbers of good size yellow perch.
Although Bog Lake is not on a major canoe route to other interior BWCAW lakes, the current fish community structure and abundance should attract anglers to this lake. The lake's name is a misnomer as hard sand (not bog) is common along much of the shoreline.
