Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Status of the Fishery (as of 08/16/2010)

Bone Lake is 46 acres with a maximum depth of 51 feet, located 16 miles northwest of Tofte, MN. The preferred access route is to head north 5.9 miles on USFS Road #357, continue north (beyond Whitefish Lake) on a rough logging road 2.3 miles (parking for three vehicles). This route is rarely plowed in winter and becomes an even longer trek if travel begins from Lake County Road #7, the last plowed road. Another route begins approximately 3 miles northeast of the Windy Lake access road on Lake County Road #7. There is a parking area (four vehicles) for the access trail, then take trail 0.8 mile (east) through old logging site. This unmaintained trail leads to the far western tip of the lake. Both routes are open to snowmobile travel. Designated stream trout lake signs are posted at each access.

Bone Lake gets moderate fishing pressure in the summer although less in the winter. Splake fingerlings are stocked every even year and rainbow trout yearlings are stocked annually in this designated stream trout lake. The 2010 population assessment found splake in average numbers for the Finland area and similar to catches in previous investigations. The average length of the catch was 11.0 inches (0.45 pound); the largest splake sampled was 17.6 inches.

The 2010 brown trout numbers were below average for the Finland area; however, brown trout were meant to provide an opportunity for large fish. The average weight of brown trout was 1.44 pound (14.2 inches); the largest brown trout was 21.1 inches (3.75 pounds). Brown trout were only stocked in 2005, 2007 and 2009.

The rainbow trout sample in 2010 was about average for rainbow trout lakes sampled in the Finland area. The mean weight was 0.34 pound (9.6 inches), with the largest rainbow trout 13.7 inches. Rainbow trout populations are difficult to assess with standard sampling gear, many different methods have been tried in the Finland area without much success. Angling for rainbow trout often produces better catches than what population assessment catch rates would indicate.

Bone Lake has a large population of small white suckers which compete with the stream trout population for forage and the anglers bait.
