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.

Status of the Fishery (as of 07/25/2011)

Green Lake is the largest lake in the Chisago City area. It has three distinct basins: the north end, which is commonly called Little Green, the large windswept main basin, and the southern end, which consists of shallow bays with abundant vegetation. Green and blue-green algae flourish in the summer, with average water clarity around 4.2 feet. The lakeshore is heavily developed, with 335 homes. Two invasive plant species, Eurasian watermilfoil and curlyleaf pondweed, are present.

Walleye management includes annual fingerling stocking at a rate of one pound per littoral acre (1,228 pounds) and a 17 inch minimum harvest regulation. Walleye abundance is within the normal range for this lake type, although survey gill net catch rates have decreased since peaking in 1986. A recent management change from biennial to annual fingerling stocking may help to boost walleye numbers; however, yellow perch, an important prey for walleye, have been declining as well. A 17 inch minimum length regulation is in effect for walleye, but nearly half the walleye caught in gill nets in the 2011 assessment were 17 inches or larger.

Green lake has a quality northern pike population, with an average length of 24 inches and large fish up to 35 inches present. Largemouth bass are abundant, but most of the bass have lengths less than 12 inches. Green Lake largemouth bass require 6 to 7 years to reach a length of 12 inches.

Black crappie and bluegill are the species most frequently caught by anglers on Green Lake, and abundance of both species is normal compared with similar lakes. Although some larger individuals are present, anglers will most often see 7-8 inch crappies and 6 inch bluegills.
