Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2009 Walleye fry 100,000 1.0
2007 Walleye fry 100,000 0.9

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 07/06/2009)

McCormick Lake, also known as Third Lake, is a small lake located in northern Pine County just east of Willow River, MN. Despite the lakes abundance of shallow water acreage, a fish winterkill has never been documented. The entire shoreline and immediate watershed surrounding McCormick Lake is characterized by undeveloped forest or woodland and marshland. Currently, the property around most of the shoreline is state owned. State forest land makes up most of the surrounding acreage while a general use Aquatic Management Area (AMA) makes up a buffer strip around the lakes shoreline. Activities allowed on general use AMA's includes angling, wildlife observation, hunting, trapping, and collection of edible seeds, fruits or mushrooms for personal use. Dogs are allowed to enter these areas, but operation of motorized vehicles is not allowed. A public boat launch is located on the northwest end of the lake. The fish population in McCormick Lake is managed for northern pike primarily with bluegill sunfish, black crappie, and largemouth bass as the secondary management species.

A standard lake survey was conducted during the week of July 06, 2009 to evaluate the current status of the fish population, the physical, chemical, and biological factors concerning habitat, and the water quality. Evaluation of the fish population utilized spring night electrofishing, two gill nets, and nine trap nets. Northern pike were normal in both numbers and size for this lake type. Pike lengths extended from 14.3 to 27.4 inches. Spring night electrofishing sampled only one largemouth bass, down from 19 in 1999. Both bluegill sunfish and black crappie were found at normal abundance levels. Lengths extended from 3.7 to 6.6 and 4.4 to 10.4 inches respectively. Average size was below normal levels for both fish species. Yellow perch abundance has historically been low in McCormack Lake. The 2009 assessment was no exception. Perch ranged from 6.0 to 7.1 inches in length. Other fish species present during the 2009 survey included brown bullhead, white sucker, hybrid sunfish, and pumpkinseed sunfish.
