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 Lake Cowdrey through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. At 14.6 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 52 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 14.6 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 52 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.

MN DNR · in their words

From the 2025 survey

Lake Cowdry is a 243-acre moderately fertile basin located a few miles northwest of downtown Alexandria in Douglas County. Maximum and mean depths are approximately 52 and 25 feet, respectively. Lake Cowdry lies within the Long Prairie River watershed. Primary inflows come from Taylor Lake via a navigable (small boats only) culvert under Lake Cowdry Road NW. The lake outflows to Lake Darling via a channel that runs under the Central Lakes Trail. A concrete leveling sill within this channel limits navigation to mostly non-motorized watercraft (canoes, paddleboards, kayaks, etc.). Residential development surrounds the majority of the shoreline. Water quality and clarity are considered good and have further increased in recent years following zebra mussel infestation. Secchi disk readings often exceed 15 feet during summer months. A public water access is located on the northeast shore off of E Lake Cowdry Road.

A standard lake survey was completed during summer 2025 to assess the fish community of Lake Cowdry. Survey methodology included electrofishing, gill nets, and trap nets. Survey results were indicative of a typical bass-panfish fishery found in smaller, heavily vegetated basins in west-central Minnesota. Largemouth Bass and Northern Pike were abundant but most of the catch was comprised of small- to medium-sized fish. Mean size of bass collected with electrofishing was 10.8 inches but bass up to 18.9 inches were sampled. Mean length of Northern Pike was 21.0 inches. Very few pike exceeding the upper end of the North-central zone protected slot limit (i.e., 26 inches) were captured. Anglers are encouraged to harvest these surplus smaller pike that are below the protected slot limit (i.e., 22 inches).

Panfishes dominated net catches in 2025. Bluegill, Pumpkinseed and hybrid sunfishes are all abundant. These populations consist of mainly smaller fish in Lake Cowdry, but a few sunfish over 8 inches were observed in the survey. Bluegill growth rates are slow, most of the Bluegill over 8 inches were at least 10 years old. Black Crappie catch rates were low, but they are typically hard to sample in these mid-summer surveys. Large schools of Black Crappie were observed in shallow water during the spring Largemouth Bass survey. Yellow Perch were present but this population is limited and is typically not targeted by anglers. Walleye were also present in small numbers due to previous stockings and likely emigration from connected basins. Regular Walleye fingerling stockings were discontinued by the MN DNR in 2016 due to extremely poor survival of stocked fingerlings. The current stocking strategy consists of surplus stockings of larger Walleye, when available, to maintain a limited fishery.

Other fish species sampled during the 2025 survey include Bowfin (Dogfish), Brown Bullhead, Common Carp, Rock Bass, Shorthead Redhorse, White Sucker, and Yellow Bullhead. The next standard MN DNR lake survey is tentatively scheduled for 2031.

Lake Cowdry is designated as an infested waterbody due to the presence of zebra mussels. This infestation was first confirmed in 2011.
