No recent survey rating

No recent survey rating.

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 Lower Comstock Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. In 4 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 76% 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 4 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 76% 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.

MN DNR · in their words

From the 2018 survey

Lower Comstock is a 160 acre lake located about 6 miles south of Markham, MN. The lake is accessed through a DNR administered public access on Upper Comstock Lake, then navigating up the channel to Lower Comstock Lake. Maximum depth is 30 feet, with about 76% of the lake less than 15 feet deep. Lower Comstock was last assessed in 2000. Lower Comstock was surveyed during the summer of 2018 to update information about fish populations.

Lower Comstock is stocked with 121,000 Walleye fry every even year. Walleye abundance of 2.5 per gillnet lift is average compared to other similar Minnesota lakes. Average length was large at 18.0 inches. Ninety percent of the Walleye aged corresponded to stocked year-classes suggesting limited natural reproduction.

Read the full DNR narrative

Black Crappie and Bluegill population densities were average compared to other similar Minnesota lakes. Black Crappie average length was 7.0 inches, but angling success and size should improve in 2019 and beyond with strong 2015 and 2016 year-classes maturing. Quality Bluegill angling opportunities exist with nearly 25% of the trapnet sample exceeding 8 inches in length. Bluegill average length was 6.6 inches.

Northern Pike abundance of 4.0 per gillnet lift was average compared to other Minnesota lakes of similar type. Average length from the gillnets was only 19.7 inches, but some large Northern Pike are present in Lower Comstock. The trapnets captured two large specimens that approached 40 inches in length.
