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 Long Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. At 13 ft of clarity, fish them deeper and lighter than usual.
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. On a lake that drops to 128 ft, check the deep edge of that structure too.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.

Northern pike

Spring
Pike are in the shallow bays and along new weed growth. At 13 ft of clarity, fish them deeper and lighter than usual.
Early summer
Pike are on the outside weed edge and points.
Summer
Pike are on the deep weed edge and points near the coolest water they can find. On a lake that drops to 128 ft, check the deep edge of that structure too.
Fall
Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops.

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

Long Lake is a 1,273-acre lake located in north-central Otter Tail County. The southwest shoreline of the lake abuts the city of Vergas, MN. Long Lake is composed of two distinct basins. The west basin is characteristic of an oligotrophic lake (i.e., deep and unfertile) while the east basin is characteristic of a mesotrophic lake (i.e., moderately deep and fertile). Several intermittent inlets are located along the north and south shorelines. An outlet to the Otter Tail River is located along the east shoreline. The inlets and outlet are not navigable by boat. The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. The maximum depth is 128 feet; however, 42% of the lake is 15 feet or less in depth. Historically, secchi disk readings have ranged from 8.0 to 18.1 feet.

Development is scattered around the entire shoreline of the lake and consists of homes, cottages, and resorts. Approximately 40% of the shoreline remains undeveloped mixed hardwoods. A DNR owned concrete public water access is located off of State Highway 228 along the northwest shoreline of the lake. A city park is located along the west shoreline of the lake. A disabled accessible fishing pier is located in the park and is available for public use. The shoal water substrates consist primarily of sand and gravel. Large stands of hardstem bulrush and common cattail are prevalent around the entire shoreline of the lake. Emergent aquatic plants such as bulrush and cattails provide valuable fish and wildlife habitat, and are critical for maintaining good water quality. They protect shorelines and lake bottoms, and can absorb and break down polluting chemicals. Emergent plants provide spawning areas for fish such as Northern Pike, Largemouth Bass, and panfish. They also serve as important nursery areas for all species of fish. Because of their ecological value, emergent plants may not be removed without a DNR permit.

Long Lake can be ecologically classified as a bass-panfish-walleye type of lake and this is reflected in the assemblage of the fish community. Walleye, Northern Pike, Largemouth Bass, and Bluegill are the dominant gamefish species. The prolificacy of these species can be attributed to the abundance of suitable spawning habitat that is available. A targeted survey (special gill netting) was conducted in 2024 to assess the Walleye and Northern Pike populations.

Walleye ranged in length from 9.3 to 26.2 inches with an average length and weight of 16.6 inches and 1.9 pounds, respectively. Walleyes attain an average length of 15.9 inches at four years of age.

Northern Pike ranged in length from 17.7 to 38.0 inches with an average length and weight of 22.8 inches and 2.6 pounds. Age data indicate that pike reproduction is consistently good. Northern Pike exhibit fast growth with an average length of 22.4 inches at four years of age.

Anglers can maintain the quality of fishing by practicing selective harvest. Selective harvest encourages the release of medium to large size fish while allowing the harvest of the more abundant smaller fish for table fare. Releasing the medium to large fish will ensure that the lake will have enough spawning age fish on an annual basis and will provide anglers with more opportunities to catch large fish in the future.

Long Lake was designated as infested with zebra mussels in 2018. Aquatic invasive species are threatening Minnesota waters. Aquatic invasive species can potentially harm water quality, water recreation, aquatic habitat, native species, and fish populations. Anglers can help prevent the introduction and spread of invasive species by following watercraft transportation laws.
