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 07/22/2013)

Lake Independence is an 844-acre lake located in western Hennepin County in the city of Maple Plain. Baker Park Reserve (Three Rivers Park District) borders the southeast portion of the lake and provides a two-lane concrete boat access (subject to park hours and parking fee) as well as shore fishing, a swimming beach and recreation area. The lake stratifies strongly in mid-summer, and dissolved oxygen levels below 15 feet can be low during this time.

Lake Independence is primarily managed for its Walleye, Muskellunge, and Yellow Perch fisheries. Present management includes Walleye fingerling stocking in odd-numbered years and Leech Lake brood Muskellunge stocking in even-numbered years. In 2013, a fisheries population assessment was made, consisting of 12 gill net sets during the last week of July, followed by 12 trap net sets during the first week of October.

Walleye abundance (8.4/gill net) is high for this type of lake. Average length and weight were 16.6 inches and 1.99 pounds, with the longest measuring 29.0 inches. Sixty-seven percent of sampled fish were 15 inches or longer, 30% were 20 inches or longer, and 2% were 25 inches or longer. The strong 2009 year class formed 50% of the catch. The next strongest year class was in 2011, which formed 35% of the catch. Walleye averaged 19 inches by age 4 and 22 inches by age 6.

Black Crappie abundance is very high compared to similar lakes in the state, with a catch rate of 75.0 fish per gill net. Mean length and weight of Black Crappie was 7.8 inches and 0.26 pounds. Thirty-one percent were 8 inches or longer, and the longest fish measured 11.7 inches. The 2010 year class (age 3) dominated the sample, comprising 94% of total catch. Black Crappie averaged 7.6 inches by age 3 and 9.1 inches by age 8.

Bluegill abundance is high (65.6 fish/trap net) and size is good (mean = 0.21 pounds) compared with similar lakes. Mean length of Bluegill in trap nets was 6.5 inches. Seventy-two percent were 6 inches or longer, and the longest fish measured 8.1 inches. Ages ranged from 1 to 8. The largest year class was 2010, which comprised 54% of the sample. Bluegill averaged 6.9 inches at age 7.

Northern Pike abundance has historically been low in Lake Independence, averaging 2.2/gill net over the previous 7 assessments. In 2013, 2.2 /gill net were sampled, low relative to similar lakes. Conversely, size structure is good. Eighty-eight percent were 21 inches or longer, and 38% were 28 inches or longer. Ages 2 through 5 were represented, with the 2010 year class (46%) being the most abundant. Northern Pike reached 24 inches by age 3 and 28 inches by age 4.

Yellow Perch are moderately abundant. Gill net catch, 16.4/net was above the median of its Lake Class. Yellow Perch gill net catch has declined in recent years; abundance this survey was well below the 2010 sample catch (39.3/net). Mean length and weight were 7.2 inches and 0.17 pounds. Eight percent were 8 inches or longer, and the longest measured 8.5 inches. Ages 2 through 5 were represented, with the 2010 year class (75%) being the most abundant. Yellow Perch reached 7.8 inches by age 4.

Nine Largemouth Bass were collected during the assessment; however, net sampling under-represents the true abundance. Mean size was 11.2 inches and 0.8 pounds with the largest reaching 14.1 inches and 1.7 lbs.

Spring ice-out trap netting is used to index adult Muskellunge abundance but this was not conducted in this assessment, so this survey's data is likely not indicative of relative abundance. Nine Muskellunge, with a size range of 15.9-50.0 inches, were sampled with survey nets. Lake Independence is a popular Muskellunge fishery in the western metro area.
