Brooks Lake is a small (98 acres), shallow lake located within the City limits of Cokato. It has a history of winterkill, the last one recorded in the winter of 1991-92. This was the first lake survey since 1983, although a population assessment was conducted in 1989. Test netting and electrofishing revealed that principal species are northern pike, largemouth bass, and bluegill. Northern PikeThe 2005 northern pike catch rate (4.8/gill net) is very near what we would expect for lakes similar to Brooks. The average weight of northern pike caught in gill nets was 4.0 pounds. Northern pike ranged in length from 18.7 to 31.5 inches with a mean length of 25.7 inches. In recent years Brooks Lake has gained a reputation for a small lake that produces above average size northern pike.BluegillThe catch rate of bluegill (22.8/trap net) was less than the previous test netting in 1989 (70.2/trap net) but was near the average for lakes like Brooks. Growth rates were slower than statewide averages with a seven inch fish being seven years old. Most bluegill ranged in size from 4.5 to 7.0 inches; the largest was 7.8 inches. Anglers can expect good fishing for smaller bluegill.Black CrappieNo black crappie were sampled in trap nets in 2005. However, crappies were noted in the creel during the winter of 2004-2005 and a few were observed while electrofishing for largemouth bass.Largemouth BassLargemouth bass were sampled by evening electrofishing at a rate similar to most lakes in the Montrose management area. Of the catchable size bass (greater than 8 inches), 63 percent were greater than 12 inches. The average size of bass was 12.3 inches, while the largest bass sampled was 18.3 inches and 8 years old. Anglers report good success fishing for largemouth bass on Brooks Lake.
