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 08/08/2013)

Peanut Lake is 8.4 acres with a maximum depth of 25 feet with about 70% of the lake fifteen feet deep or less. The lake water is bog-stained and brown with a Secchi disk reading of about eight feet. Brook Trout management began in 1985 with an introduction of 500 brook trout fingerlings. Peanut Lake was listed a designated stream trout lake in the late 1980's with special rules and regulations applying to that fishery. Brook Trout stocking has maintained the fishery, with no known trout reproduction occurring in Peanut Lake.

Brook trout were sampled in above average numbers in 2013, compared to other brook trout lakes with similar characteristic in the Finland area. The average weight of the brook trout was about a quarter pound, below the average for this type of lake in the Finland area. All the brook trout captured in 2013 were aged and identified as fingerlings stocked in 2012, explaining the smaller average size. When angling on Peanut Lake (winter or summer) realize that the dissolved oxygen may not be sufficient in the lower portion of the lake for brook trout to inhabit and fishing the shallower water may be more productive.

Early access to Peanut Lake was through a newly logged area, on a foot path, to the north end of the lake when stream trout management began. This route is now overgrown and not useable. An alternate access route to the south end of the lake uses a logging road for 0.5 mile and then about a 100 yard foot path across a logged area to the south end of the lake.
