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 McDonald Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. At 11 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.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.

Crappie

Spring
Crappie are up in the back bays and against wood in a few feet of water, spawning shallower than most people fish for them. At 11 ft of clarity, fish them deeper and lighter than usual.
Early summer
Crappie are pulling off the bays to the first deep weed edge and brush, still reachable shallow at dusk.
Summer
Crappie are over the basin of a stratified lake, well off any structure, which is why summer netting barely catches them inshore.
Fall
Crappie are schooled along the deep weedline and the basin edge, pushing shallow to feed at dusk while the water still turns over slowly.

MN DNR · in their words

From the 2022 survey

Schwartz Lake is a 489-acre mesotrophic (moderately fertile) lake located in north-central Otter Tail County approximately two miles west of Dent, MN. Schwartz Lake is connected to Big McDonald Lake via a shallow channel along the northwest shoreline. The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. The maximum depth is 33 feet; however, 60% of the lake is 15 feet or less in depth. Historical secchi disk readings have ranged from 11.0 to 13.6 feet.

Shoreline development is limited to the south shoreline. A DNR owned concrete public water access is located along the southwest shoreline. Shoal water substrates consist primarily of sand and gravel. Areas of hardstem bulrush and common cattail are located throughout the lake. Emergent aquatic plants such as bulrush and cattail provide valuable fish and wildlife habitat, and are critical for maintaining good water quality. They protect shorelines and lake bottoms, and can actually 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 nursery areas for all species of fish. Because of their ecological value, emergent plants may not be removed without a DNR permit.

Read the full DNR narrative

A spring trapnetting survey was conducted to analyze the Black Crappie population. Catch and length data indicate that an abundant Black Crappie population with a high quality size structure exists in Schwartz Lake. Black Crappies ranged in length from 7.4 to 13.9 inches with an average length of 11.4 inches. Eighty-four percent of the Black Crappies were 10.0 inches or greater in length and 36% were 12.0 inches or greater in length. Black Crappies attain an average length of 10.8 inches at five 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.

Schwartz Lake was listed as infested with zebra mussels in 2019. Aquatic invasive species are threatening Minnesota waters. The non-native 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.
