Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Adley Lake is a 239-acre eutrophic (very fertile) lake located in southeastern Otter Tail County. The city of Parkers Prairie abuts the north and west shorelines of the lake. The immediate watershed is primarily composed of residential and commercial areas along with small tracts of agricultural land. Adley Lake has a maximum depth of 20 feet; however, the majority of the lake is less than 10 feet in depth. Consequently, the lake is subject to periodic partial winterkill. The Parkers Prairie Sportsmen's Club operates an aeration system during severe winters, which has recently minimized the severity of winterkills. The most recent partial winterkill occurred in 1996-97. The secchi disk reading during the survey was 11.0 feet. Previous secchi disk readings ranged from 1.5 to 4.2 feet. A city park is located along the east shoreline of the lake The park includes amenities such as picnic shelters with electricity, playground equipment, fire pits, volleyball nets, and a concrete public water access. Shoal water substrates consist primarily of gravel and sand. Hardstem bulrush and common cattails are abundant in several areas around the lake; however, they are most prevalent in the southern basin. These emergent plants provide valuable fish and wildlife habitat and are critical for maintaining good water quality. They provide critical spawning and nursery habitat for species of fish such as Northern Pike, Largemouth Bass, and panfish. They protect shorelines from erosion and can absorb and break down pollutants. Because of their ecological importance, bulrush and cattails may not be removed without a DNR permit. A standard fisheries survey was conducted to analyze the fish community of Adley Lake. Walleye, Northern Pike, Largemouth Bass and Bluegill are the dominant gamefish species present. Walleyes are moderately abundant. Walleyes ranged in length from 12.2 to 26.3 inches with an average length and weight of 19.0 inches and 2.5 pounds. Walleyes attain an average length of 14.9 inches at four years of age. A viable Walleye population is sustained by Walleye stocking efforts from MN DNR Fisheries and the Parkers Prairie Sportsmen's Club. Northern Pike abundance is also at a moderate level. Northern Pike ranged in length from 17.2 to 31.4 inches with an average length and weight of 22.0 inches and 2.3 pounds. Northern Pike growth is fast as they attain an average length of 23.3 inches at four years of age. A very abundant Largemouth Bass population with a quality size structure is present. Age data indicate that bass exhibit consistently good reproduction.…
