Privately Stocked Fish
* indicates privately stocked fish. Private stocking includes fish purchased by the DNR for stocking and fish purchased and stocked by private citizens and sporting groups.

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 07/31/2006)

Woman Lake is a 5496-acre lake with a maximum depth of 54 feet located in northern Cass County about three miles west of Longville. Two Minnesota Department of Natural Resources (DNR) public accesses are located on Woman Lake. The DNR classifies Minnesota's lakes into 43 different lake classes based on physical and chemical characteristics. Woman Lake is in Lake Class 22, and this Lake Class can be characterized as very large, deep, and irregularly shaped lakes with clear water.

The DNR Section of Fisheries operates a walleye spawntake trap on Boy River upstream from Woman Lake. On average, about 20% of the adult walleye population in Woman Lake goes up the Boy River each year to spawn and the remaining 80% spawn in the lake. Walleye fry that result from eggs taken at the Boy River are stocked into other lakes that have little or no natural walleye reproduction. Typically, walleye fry equal to 10% of the eggs taken are returned to Woman Lake to assure no negative impact on the walleye population.

Woman Lake provides good to excellent fishing for many species of fish. During surveys of anglers in 1996, 1997, 2005, and 2006, most anglers targeted walleye or walleye in combination with other species, but yellow perch was the most commonly caught species. Other species popular with Woman Lake anglers are black crappie, largemouth bass, muskellunge, northern pike, rock bass, smallmouth bass, and sunfish.

Yellow perch are an important food for predator fish and are a popular sport fish for anglers. The majority of the yellow perch were small (5 - 7 inches); however, Woman Lake can provide angling for perch up to 13 inches. The walleye abundance was similar to previous surveys with many ages present. The average length of fish sampled was 16 inches, and over half the fish were greater than 15 inches. Catches of northern pike in 2006 DNR sampling was similar to earlier years on Woman Lake. Many small fish (14 to 20 inches) were sampled and the average length of all fish sampled was 23 inches. A 24- to 36-inch protected slot regulation was implemented in 2003 to improve the size structure of northern pike on the Woman Lake Chain (Child, Girl, Little Woman and Woman Lakes).

Woman Lake has an abundant population of rusty crayfish. Rusty crayfish, an exotic species, has been present since prior to 1984. It is unlawful to transport live crayfish to other waters or to use them as bait in waters other than where they were taken.

Anglers can help maintain or improve the quality of fishing, which has decreased on many lakes, by practicing selective harvest. Selective harvest allows for the harvest of smaller fish for table fare, but encourages release of medium- to large-size fish. Releasing these fish can help maintain balance in the fish community in Woman Lake and provide anglers with opportunities to catch more and larger fish in the future.

There has been much development on Woman Lake. From 1948 to 2003, the number of lake homes drastically increased from 140 to 551. Shoreline areas (on the land and into the shallow water) provide essential habitat for fish and wildlife that live in or near Minnesota's lakes. Overdeveloped shorelines cannot support the fish, wildlife, and clean water that are associated with natural undeveloped lakes. Some portions of the shoreline have remained undeveloped and become a vital component in maintaining the water quality and fish habitat. As the demand for lakeshore lots increases, the development of the remaining shoreline of Woman Lake remains very likely.

Shoreline habitat consists of aquatic plants, woody plants and natural lake bottom soils. Plants in the water and at the water's edge provide habitat, prevent erosion and absorb excess nutrients. Shrubs, trees, and woody debris such as fallen trees or limbs provide good habitat both above and below the water and should be left in place. By leaving a buffer strip of natural vegetation along the shoreline, property owners can reduce erosion, help maintain water quality, and provide habitat and travel corridors for wildlife.
