Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Oak is a shallow, eutrophic, 339-acre lake located in northern Carver County near the city of Watertown. It is primarily managed for northern pike and secondarily largemouth bass and bluegill. The lake is occasionally stocked with walleye by a landowner who lives on the lake (with a permit from the DNR). Oak lake is subject to periodic winterkill so a permit to aerate has been submitted by the landowner as well. In August 2011, a population assessment was conducted to determine the size structure and abundance of game fish in the lake. Walleye abundance is high (7.3/gill net) in Oak Lake, although the population seems to be aging. In the 2005 assessment, catch averaged 26.7 walleye per gill net, and consisted of smaller younger age-3 and age-4 individuals averaging 15.4 inches and 2.0 lbs. The current population is larger and older averaging 21.2 inches and 3.7 lbs. The largest fish measured was 27.2 inches and 7.1 lbs. Eighty-two percent of the walleye were 15 inches or longer, 52% were 20 inches or longer, and 23% were 25 inches or longer. Walleye body condition was fair, with the larger fish being in better condition than the smaller. Walleye were present from the 4 most recent stockings. The majority (64%) of the population was comprised of age-10 individuals from the 2001 fry stocking. Walleye from the 2002 (9%), 2005 (7%), and 2006 (4%) year classes were also present. Age-2 (11%) and age-3 (4%) walleye were present as well. Walleye were not stocked in these years indicating illegal stocking may have occurred due to the low likelihood of fish migration or natural reproduction. Age-2, 3 and 6, walleye grew fast, however growth was slow for all other year classes. Walleye averaged 13.1 inches by age-2, 24 inches by age 6, and 21.6 inches by age-10. The northern pike population is moderately low for its lake type (2.3/gill net). Pike have not been collected in high abundance since 1995 (when 10.3 per gill net were observed). Winterkill has occurred since then and may explain the shift in population abundance. In 2011, northern pike averaged 23.1 inches in length and 2.8 lbs, with the largest reaching 27.3 inches and 4.4 lbs. Eighty-nine percent were 14 inches or longer and 78% were 21 inches or longer. Northern pike displayed good body condition. Ages ranged from 1 through 6, with 44% age 5. Growth was average compared with statewide averages. Ten largemouth bass were collected during the assessment; however, passive sampling gears, such as trap nets and gill nets, are not effective methods for collecting largemouth bass.
