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 06/21/2010)

Lake Minnewaska is a 7,110-acre lake located in central Pope County between Glenwood and Starbuck. For its size, Minnewaska is relatively shallow. Maximum depth is just 32.0 feet. It is the largest lake in the county and is a popular destination for anglers and recreational boaters. Swimming is also a popular activity during summer months. Municipal swimming beaches are located in Glenwood and Starbuck. Three public accesses are available. Two occur on the northeast side of the lake near Glenwood. The third access is located within the Starbuck Marina. Residential development occurs around the entire shoreline.

Lake Minnewaska supports a diverse fish community and offers a wide range of fishing opportunities. The lake is managed for walleye. Largemouth bass and other sunfishes are also important to the fishery. Although walleye abundance has decreased in recent years, gillnet catches remained above expected rates. Catches averaged 6.9-walleye/gill net in 2010. Mean size of captured walleye was 16.5 inches and 1.8 pounds. Walleye growth rates are relatively fast with fish usually exceeding 16.0 inches in length after their fourth growing season. Typical of most large walleye fisheries, natural reproduction accounts for much of the population abundance. However, walleye fry and fingerlings are routinely stocked to supplement and increase walleye numbers. The DNR stocks fry on an annual basis. Fingerling stockings are prescribed following documentation of two consecutive poor year classes. Walleye fingerlings are also stocked by the Lake Minnewaska Association.

Other gamefishes targeted by anglers include largemouth and smallmouth bass, bluegill, black crappie, northern pike, and yellow perch. Largemouth and smallmouth bass populations have expanded in recent years. Anglers can expect good catch rates of medium- to large-sized fish. Lake Minnewaska has become a popular choice for organized bass tournaments. Bluegill are also abundant and size structure of this population should prove attractive to panfish anglers. Mean size of 2010 captures was 6.2 inches and 0.2 pounds. Record-high black crappie abundance was documented in 2010 due to an extremely strong 2007 year class. Crappie fishing, in terms of both numbers and size, should greatly improve in the near future as this dominant year class recruits to a harvestable size. Northern pike abundance continues to increase. In fact, pike numbers have not been this high since the mid 1990s. Gillnet catch rate exceeded levels expected for this type of lake. Mean length of the 2010 capture sample was only 19.7 inches but large pike were recorded in the pike catch. Numerous pike exceeding 30.0 inches in length were captured. The largest pike measured was nearly 36.0 inches. Yellow perch catches averaged 31.5-fish/gill net. Harvestable-size perch are present, but the greatest proportion of the population is comprised of smaller fish.

Other fish sampled in the 2010 survey included bigmouth buffalo, black, brown, and yellow bullhead, bowfin (dogfish), common carp, freshwater drum (sheepshead), hybrid sunfish, pumpkinseed sunfish, tullibee (cisco), and white sucker. The next lake survey is scheduled for 2014.

Fishing pressure on Lake Minnewaska can be heavy at times, during both open water and winter seasons. To help maintain fishing quality, anglers are encouraged to practice selective harvest. The selective harvest concept promotes release of larger fish and harvest of more abundant smaller fish for eating. Releasing medium to large fish will ensure the lake will sustain enough spawning age fish and provide anglers with opportunities to catch more large fish in the future.

Eurasian water milfoil and curly-leaf pondweed are present in this basin. To reduce spread of these undesired exotic invasives, all boaters must remove all aquatic vegetation from their boat and trailer before leaving the public access. For more information on how to reduce the spread of exotic species via water recreation visit the Minnesota Department of Natural Resources website at http://www.dnr.state.mn.us/invasives/preventspread.html.
