On 28 Minnesota Lakes, Half or More of DNR Survey Crappies Reached 10 Inches

IBig Crappie Share

One in Nine Hit 10 Inches, Half or More on 28 Lakes

Among the 496 lakes the median had 8.8% of its crappies at 10 inches or longer. The list below draws the 28 from survey records in LakeFinder and pairs each lake's trap-net catch with its share. LakeFinder rounds its whole-inch bins down, so a crappie in the 10-inch bin was at least 10.0 inches long. For 978 of 1,111 DNR narrative maximum lengths ending in .5 or more, the top bin matched the rounded-down inch.

IISize With Numbers

Five Lakes Matched Size With Numbers When Pooled Over 2016 to 2025

A high share can come from very few fish. Pine Mountain in Cass County had 80% of its crappies reach 10 inches or longer and averaged 0.2 per trap net. That kind of lake is worth checking for one big fish rather than a mess of them. Independence Lake in Jackson County leads the list with 75 of 78 crappies at 10 inches, and the DNR's 2023 lake narrative plainly says that "Other species sampled in low abundance included Black Crappie and Largemouth Bass."

With surveys pooled over 2016 to 2025, five lakes match size with numbers. Moon Lake in Douglas County put 157 of 269 measured crappies at 10 inches and averaged 12.9 per trap net. Whiskey Lake in Douglas County put 59 of 102 at 10 inches and averaged 9.3 per net. Lady Lake in Todd County put 269 of 418 there and averaged 7.4. Christianson in Lake County at 5.7 per net and Betty in Meeker County at 5.2 complete the five. Lady and Christianson show that pairing only in the pooled figures.

IIINewest Survey Check

Five of Eight Repeat-Surveyed Lakes Beat Half in Their Latest Survey

Sixteen of the 28 had at least 75 crappies measured in their latest survey from 2016 to 2025, enough to read that survey on its own. Eight of the 16 have just that one survey, making their latest survey the one that earned them a place on the list. Among the eight with an earlier survey as well, five had half or more at 10 inches in the latest survey. Those lakes are Little Turtle, Stowe, Maple, Moon and Little Swan. In 2024 three dropped below half.

Douglas County has 7 of the 28 lakes and three of those five are Moon, Maple and Stowe. The share of measured crappies at 10 inches rose from 25% of 20 in 2017 at Moon, 33% of 69 in 2019 at Maple and 23% of 83 in 2019 at Stowe. Moon's 2023 survey found 61% of 249 crappies at 10 inches and caught 25.2 per trap net. Maple had 202 of 295 at 10 inches in 2025, and Stowe had 63 of 81 there that same year.

Lady dropped from 84.9% of 238 crappies in its 2016 survey to 37.2% of 180 in 2024. With no standard trap nets set the 2016 sample came from electrofishing, gill nets and special trap nets and held 202 of the 269 crappies at 10 inches in Lady's pooled 2016 to 2025 surveys. Lady's only survey with standard trap nets was in 2024. Its narrative states "Spring electrofishing produced an even larger sample of 109 crappies." That narrative also says that "The trap netted crappie averaged 10 inches long and 3 fish were over 12 inches." Wild Rice fell to 41.3% of 75 in 2024. Christianson finished just below half in 2024 with 50 of 101.

Special crappie rules are already in place on some lakes. LakeFinder shows a 10-inch minimum on Stuart and Maple and a five-crappie daily limit on West Battle, Wild Rice, Inguadona and Maple.

IVDNR Sampling Gear

Spring Gear Catches Larger Crappies

The DNR's sampling glossary describes the trap net as "the main piece of equipment used for sampling bluegill, crappie, and bullheads." Gill nets target other species, and the DNR describes them as "the main piece of equipment used for sampling walleye, northern pike, yellow perch, cisco, whitefish, trout, and salmon." Gill nets still caught 45.0% of the crappies in the 2016 to 2025 surveys, standard trap nets caught 42.4% and other gear caught 12.6%.

The length counts combine every gear used in a survey, so we checked whether extra gear changes the result. In 1,878 surveys where standard trap and gill nets caught every crappie, 10.5% of measured crappies were 10 inches or longer. In 186 surveys where other gear caught more than a tenth of the crappies, that share reached 17.2%. Surveys in April or May found 14.9% at 10 inches compared with 11.4% in summer surveys. The DNR's Whiskey Lake narrative offers a reason in its own words. "Spring surveys also offer the opportunity to sample larger Black Crappie (>8"), which can be difficult to sample in mid-summer surveys."

VThin Survey Records

Most Lakes Listed Rely on One or Two Surveys

Among the 28 lakes, 23 rely on one or two surveys and 17 on fewer than 150 fish. One strong year class can put a lake on the list and take it off at the next survey. Gear also muddies comparisons with earlier surveys. The statewide share ran 6.0% in 1990s surveys across 888 lakes compared with 11.6% from 2016 to 2025, but trap nets caught 69.1% of the crappies then compared with 42.4% now. Some lake figures come from a 2016 or 2017 survey, so check the tables for the latest survey year. The gear figures exclude 10,097 crappies caught in seines. LakeFinder regulations were checked in October 2026 and may have come after the surveys.

VIPlanning A Trip

Moon and Stowe Passed Both Bars in Their Latest Surveys

Our read is that a lake earns a place near the top of a crappie trip plan when half or more of its measured crappies reached 10 inches and its trap nets averaged five or more per net. Moon passed both bars in its 2023 survey and Stowe in its 2025 survey, making those the first two lakes we would fish. Whiskey and Betty passed both in older single surveys from 2021 and 2017, while Lady and Christianson passed them only in pooled figures. Before driving to the lake, read its LakeFinder narrative to see how the DNR caught its sample.
