Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.

How to fish Moulton Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. In 3.2 ft of visibility, they sit shallower than you think.
Early summer
Walleye are setting up on the outside weed edge, points and shallow structure.
Summer
Walleye are working the weed edge, points and any wind-blown structure. With 85% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.

Largemouth bass

Spring
Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn. In 3.2 ft of visibility, they sit shallower than you think.
Early summer
Largemouth are on the shallow spawning flats and protected bays, where beds go on firm bottom next to isolated cover.
Summer
Largemouth are in and along the weeds: cabbage and milfoil edges, matted cover and shade. With 85% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Largemouth are chasing bait back onto the flats and into the remaining green weeds, feeding hard and shallow before the freeze.

Longest fish measured by DNR survey crews in each year's nets. Survey gear samples the population, so the lake usually holds larger fish than any survey measured.

MN DNR · in their words

From the 2024 survey

Moulton Lake is a secluded lake located along the Aitkin-Crow Wing county line. Most of the shoreline is unaltered and publicly owned. There is a state-owned public access located in the northwest corner of the lake, accessible through a state forest road off of Aitkin County Road 3. The water is soft and heavily bog stained with a Secchi disc reading of only 3 feet. Anglers fishing Moulton Lake have several species to target with Walleye, Black Crappie, and Northern Pike being the most popular, but opportunities to catch Largemouth Bass and Bluegill also exist.

A spring trap net survey (May 15) and gill net-only targeted survey (Aug 19) were performed on Moulton Lake to assist with review of the walleye stocking plan, assess the panfish population, and to harvest panfish spp. (Black Crappie, Bluegill, Hybrid Sunfish) for stocking at Long Lake (01-0101-00) in central Aitkin County. Long Lake had recently experienced a severe winterkill.

The gill net catch rate for Walleye was 1.3 per gill net, which did not meet the management goal of 2 to 4 fish per gill net. Six year classes of Walleye, from 1 to 18 years old, were observed and all were from years that were stocked. Walleye in gill nets averaged 16.6 inches and ranged from 8.2 to 27.6 inches. Growth rates were slow compared to county and state averages, with 4-year-old Walleye averaging 13.5 inches, which is typical for Moulton Lake. Fingerling stocking supports the Walleye population in Moulton Lake and they have been stocked annually since 2022. Although trace amounts of natural reproduction have been noted in the past, it does not appear to contribute significantly to the fishery. Also, no fish were observed from the 2019 or 2021 year classes, which had been fry stocked.

Northern Pike relative abundance was unchanged from 2021 (1.67 per gill net). Size structure was favorable with a mean length of 27.5 inches and individuals up to 34.9 inches were observed. Fifty percent of Pike captured were greater than 26 inches. Northern Pike ranged from 4 to 7 years old, and displayed fast growth compared to state and county averages, reaching 23 inches in 4 years.

Catch rates of Black Crappie in gill nets decreased from an all-time high in 2021 (28.7 per net), to a rate of 14.0 per net. While a decrease in relative abundance was observed, the gill net catch rate of Crappie still exceeded the normal range for this type of lake, as well as the historical median prior to 2021 (5.4 per net). Black Crappie were captured at a rate of 16.7 per trap net during the spring survey, which was hgher than what is usually observed in standard surveys in mid-summer (1-7 per trap net). Size structure of Crappie captured in trap nets was slightly wider than from gill net-captured fish and ranged from 4.9 to 11.6 inches and averaged 8.4 inches. For comparison, gill net-captured Crappie averaged 8.0 inches and ranged from 4.3 to 9.7 inches. Crappie ranged from 1 to 7 years old, with only the 2019 year class (age 5) missing from the sample. Growth rates continued to be below state and county averages, with 4-year-old Crappie averaging only 7.0 inches. Two hundred Crappie from the trap net sample were transferred to Long Lake.

Trap net catch rates for Bluegill were 37.0 per net, which is substantially higher than what has been observed during previous standard surveys in August (5-13 per trap net). Seven percent of Bluegill captured were over 8 inches in length, which was similar to the 2021 standard survey (6%). While typically not used to index Bluegill abundance, the gill net catch rate of 9.8 per net was the highest observed in any previous surveys. One hundred and thirty Bluegill and a combination of 20 Hybrid Sunfish and Pumpkinseeds from the trap net sample were transferred to Long Lake.

Largemouth Bass are not particularly abundant at Moulton Lake. Only two Largemouth Bass were sampled during the 2024 gill net survey, but did include one fish over 19.2 inches. Eight more Bass were observed in the spring survey and they averaged 12.0 inches long, with one fish reaching 19.3 inches.

The Yellow Perch catch rate in the gill nets (10.7 per net) continued an upward trend that first appeared in 2021 (6.2 per net). In the nine gill net surveys from 1968 to 2016, Perch abundance had been quite stable and averaged 2.3 per net with the narrow range of 1.2 to 3.3 per net. Perch sizes ranged from 5.4 to 9.6 inches long, with a mean length of 7.4 inches. No perch were observed in the spring trap net sampling.
