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.

Fish Consumption Guidelines

These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Status of the Fishery (as of 06/09/2008)

Splake abundance in 2008 was average compared to other stream trout lakes in the Grand Marais area, while the average size of the splake collected in 2008 was higher than usual for fish taken in a spring assessment. Most of the splake collected in 2008 were survivors of a 2006 fingerling stocking, although a few fish from the 2005 and 2007 stockings were also taken. Growth rates for stocked splake had been faster than average, with fishing reaching a length of 10.6 inches at the end of their second year in the lake. Few rainbow trout were taken in 2008, despite their having been stocked just a few days before the assessment. It is likely that something in the behavior of those newly-stocked fish kept them out of the reach of gill nets and trap nets used in this assessment.

In addition to trout, Pine Lake supported a small number of bluegill in 2008, some of which were large enough to have been of interest to anglers. The lake also supported fairly high numbers of white sucker, but good growth observed for the splake taken in 2008 suggested that high white sucker numbers were not necessarily a problem in this lake. Walleye and smallmouth bass, which have been found in this lake in the past, were not found in 2008. That was very good news, since both species are highly undesirable in stream trout lakes.
