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 08/04/2008)

Lake Waconia in Carver County is a 2,996-acre lake that has a diversity of aquatic habitats which create a popular multi-species fishery. The lake is primarily managed for walleye, largemouth bass, and muskellunge and secondarily for bluegill, black crappie, and yellow perch. In 1988, a 16-inch minimum size limit was implemented for walleye in an effort to reduce the harvest of small walleyes. A population assessment was conducted in August 2008 to determine the abundance and size structure of the fish community.

Walleye are moderately abundant (5.2 per gill net) compared to other class 27 lakes in the state. Gill net catch has remained relatively stable over the previous 4 assessments (2002-2008) averaging 5.1 walleye per net. Mean length and weight were 18.6 inches and 2.6 pounds, with the longest measuring 29.3 inches. Eighty-five percent of walleye sampled were 15 inches or longer, 34% were 20 inches or longer, and 7% were 25 inches and longer. Ages ranged from 1 to 15,with the strongest year-classes stocked in 2001, 2005, and 2007. These 1, 3, and 7 year-old fish comprised 87% of the fish sampled. Walleye tended to reach the 16-inch minimum length limit by age 4 or 5 and 80% were harvestable size, similar to the 2006 assessment. There was some evidence of natural reproduction from the 1996 and 2006 year classes, however it was only 3.6% compared to 22.5% found in 2006. In 2008, walleye grew fast until age 4, then slowed to below average. Walleye continue to be stocked in Lake Waconia on odd numbered years.

Neither largemouth bass nor muskellunge are sampled effectively with the gear used during summer population assessments. Therefore the data presented may not be indicative of the population abundance or size structure. Two largemouth bass were collected in gill nets measuring 13.1 inches and 1.1 pounds and 20.1 inches and 5.3 pounds. Five bass were collected in trap nets averaging 16.8 inches and 2.6 pounds. One muskellunge was collected in a trap net and measured 44.3 inches and weighed 22.0 pounds.

Bluegill abundance was moderately high with catch rates averaging 30.4 per trap net. Bluegill catch in trap nets has remained stable over the previous 6 assessments (1993-2006, mean = 29.6 per trap net) with the exception of 2006 which seems to be an outlier as only 5.6 were collected per trap net. Average length and weight were 5.6 inches and 0.15 pounds, with the largest measuring 8.2 inches in length. Mean weight was somewhat lower than the average for the previous 7 assessments at 0.20 pounds. Forty-one percent of bluegill were 6 inches or greater and less than one percent were 8 inches or greater. Bluegill were sampled up to age 9, with 22% age 2, 33% age 3, and 20% age 6. Growth in 2008 was slower than average.

Black crappie catch in both gill nets (14.2/net) and trap nets (6.7/net) was high compared to other class 27 lakes in the state. Gill-net catch has been stable over the previous 6 assessments (1993-2006) averaging 14.9 per net; however, trap net catch has been erratic and averages 7.8 per net. Average length and weight of black crappie in gill nets was 7.4 inches and 0.25 pounds, with the longest measuring 13.9 inches in length. Forty percent were 8 inches and longer and less than one percent were 10 inches and longer. Black crappie were age 1 to 9 with no age 7 or 8 fish sampled. Eighty-three percent were age 3 or younger. Growth in 2008 was slower than average.

Yellow perch abundance was moderately low at 8.5 per gill net. Historically, Waconia has had a moderately low density yellow perch population averaging 13.2 per gill net over the previous 6 assessments (1993-2006). Average length and weight were 7.0 inches and 0.15 pounds, with the largest reaching 8.5 inches in length. Eighty-nine percent of yellow perch sampled were between 6 and 8 inches in length, and only 7% were 8 inches or longer. Ages 1 through 6 were represented, with 93% either age 3, 4, or 5. Growth in 2008 was slower than average.

Northern pike are low in abundance, averaging 0.5 per gill net. This is typically the case in Lake Waconia as catch has averaged 0.8 pike per gill net in the previous 6 assessments (1993-2006). Average length and weight were 27.7 inches and 4.60 pounds, with the largest measuring 31.9 inches. Sixty-two percent were between 21 and 28 inches in length and 38% were greater than 28 inches. Ages 4, 5, and 6 were represented. Growth was slow for the first couple years then became average around age 3.

Freshwater drum are moderately abundant and were collected at a rate of 6.9 per gill net, which is fewer than in past assessments. Average drum catch over the previous 6 assessments (1993-2006) has been 13.1 per gill net. Mean length and weight were 16.5 inches and 2.19 pounds, with the largest measuring 24.2 inches. Other species collected in low abundance were black, brown, and yellow bullhead, pumpkinseed, bigmouth buffalo, common carp, golden shiner, hybrid sunfish, and white sucker
