1 fish purchased and stocked by private citizens and sporting groups. 2 fish purchased by the DNR for stocking.
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.
Maple Lake is a 777-acre lake located just east of the City of Maple Lake in Wright County. It is a popular destination and offers a variety of angling opportunities (Walleye, Northern Pike, bass, and panfish). The lake has a maximum depth of 76 feet and water quality is good. There are two public accesses on the lake, one ‘along the northeast shore and one along the southwest shore. Walleye are stocked every two years, and while catch rates remain low, individual fish are typically healthy, fast-growing, and of good size. A standard lake survey was completed in 2025 to update fisheries data last collected in 2020. In 2023, daily bag limits for panfish were reduced to help protect size quality and extend angling opportunities throughout the year. The sunfish limit was reduced from 20 to 10 fish, and the crappie limit from 10 to 5 fish per day. These changes aimed to protect and potentially improve the population size-structure and consistently produce more large individuals for anglers to catch. Emergent and floating-leaf vegetation were not mapped in 2025 but occur along much of the shoreline. Common species include cattail, white waterlily, and arrowhead. Past submerged vegetation surveys found plants growing out to a depth of 15 feet with coontail, star duckweed, and northern milfoil being the most common submersed species observed. Maple Lake is known to contain three aquatic invasive species: Eurasian watermilfoil (found in 2007), flowering rush (2015), and zebra mussels (2019). Lake users should remain vigilant to prevent the spread of these species to other lakes. Walleye are a primary managed species in the lake and the population is sustained through fingerling stocking during even numbered years. Walleye catches have historically been low and 2025 was no exception. While the Walleye catch was low, it was similar to 2020 and within the range of expected values for the lake. Walleye lengths ranged from 14 to 24 inches with an average length and weight of 19 inches and 3 pounds. Walleye ages ranged from 1 to 10 years with most fish being less than 7 years old. While Walleye abundance is low, growth is fast, reaching 20 inches in 4 years. High Northern Pike abundance likely limits Walleye survival and prevents population growth beyond current levels. Northern Pike catches in Maple have historically been high and dominated by small fish and that remained the case in 2025. Only 11% of the pike sampled were 26 inches or longer and 2% were longer than 30 inches. Northern Pike sampled in 2025 ranged in length from 13 to 33 inches with an average…
