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 06/23/2008)

Lake Byllesby is a 1,435 acre impoundment created by a hydroelectric dam on the Cannon River. Water level and clarity are subject to rapid change due to the rivers influence. High turbidity levels also impact water quality by limiting aquatic vegetation. This lack of vegetation contributes to intense summer algal blooms. The reservoir is also affected by sediment loading in the upper reaches. It is likely these factors have a strong impact on fish populations. The fishery is similar to other reservoirs in that it has numerous riverine species, as well as species more typical of a lake environment. The lake provides fair fishing during the open-water season for black crappie and channel catfish. Bluegill, walleye and northern pike are present in low numbers, although angling success seems better for walleye during the ice-fishing season. The lake may be an important wintering area for walleye and other riverine species that move downstream from the Cannon River. Crappie fishing is also fair during the ice-fishing season.
