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 Lake is a 422 acre lake in northern Pine County. A paved public access and a private resort are both located on the south shore of the lake. Water clarity is good despite sporadic algae blooms in August. Oak Lake is managed primarily for Walleye. Walleye fry have been stocked in odd years since 2017. Lake use is light to moderate for both boating and fishing. In 2023, a fisheries survey was conducted which included spring and fall electrofishing, trap netting, and gillnetting. Six gill net sets and nine trap nets were used during the assessment. The previous assessment on Oak Lake was conducted in 2015. No juvenile Walleye were sampled during the fall electrofishing survey. Adult Walleye gill net catch rates were below average for this type of lake in Minnesota. Northern Pike catch rates were 8.8 fish per net which is well above average for this type of lake. Both Northern Pike and Walleye growth was average. Bluegill and Crappie catch rates were higher in the 2023 survey than the previous survey. Black Crappies had very high catch rates; however, lengths ranged from 4.2 to 9.7 inches and only averaged 6.2 inches. Bluegill catch rates were above the normal range for this type of lake. Measured Bluegill ranged from 3.2 to 7.9 inches. Spring night electrofishing found good numbers of Largemouth Bass that had an average size of 1.1 pounds. Lengths ranged from 9.4 to 18.5 inches with an average length of 14.7 inches. Anglers can anticipate catching good numbers of moderate sized Largemouth Bass.
