2007Rates 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 Little Mantrap Lake through the year
Walleye
- Spring
- Walleye are shallow, on and just off the spawning flats and the first green weeds. At 15 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 54 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.
Largemouth bass
- Spring
- Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn. At 15 ft of clarity, fish them deeper and lighter than usual.
- 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. On a lake that drops to 54 ft, check the deep edge of that structure too.
- 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.

Largemouth Bass were sampled in good numbers again in 2022, with fish averaging 12.5 inches. The longest Largemouth Bass sampled was 17.8 inches in length. Currently, there is a special regulation for bass on Little Mantrap which states all fish from 12 - 20 inches must be immediately released, and one over 20 inches allowed in possession.
Little Mantrap has an abundant sunfish population, including Bluegill, Pumpkinseed, Green Sunfish and their hybrids. Most fish sampled were too small for anglers, but there were some nicer fish ranging up to 8 inches in length. Little Mantrap supports a healthy Black Crappie population. Special spring sampling targeting Crappies took place in 2022, with most of the fish in the 9.5 - 11.5 inch range.
Walleye abundance was better than recent years in Little Mantrap, with one trophy fish sampled at 30 inches in length. Walleyes averaged 17.8 inches in length and were spread out evenly from 13 to 20 inches. Yellow Perch, an important forage species, were sampled in very low numbers and all were under 7 inches in length.
Northern Pike abundance was at the high end of recent surveys in Little Mantrap. Anglers will find most northern from 15 - 21 inches in length, a great opportunity to take advantage of the current Northern Pike regulation. Northern Pike sampled had an average length of 18.3 inches and weighed 1.3 pounds.
Currently, no Aquatic Invasive Species (AIS) have been identified in Little Mantrap Lake. To avoid spreading AIS, lake users are required to remove all aquatic plants or animals from their watercraft and drain all water from their boat before leaving the access.
