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.
Trout Lake is a 1,890-acre lake located just south of Coleraine, MN. There are three public accesses on Trout Lake. The 2019 lake management plan lists Walleye and Northern Pike as the primary species of management with Largemouth Bass and Smallmouth Bass as secondary species. In 2005, a 17 to 26 inch protected slot length limit with only one fish over 26 inches in possession was implemented for Walleye. In 2020, the Walleye regulation was modified to 20 to 24 inch protected slot length limit with only one fish over 24 inches in possession to better align with other area lakes. The 2025 targeted survey was conducted to help evaluate management activities, including the special Walleye regulation and current stocking strategy. The management plan goal for Walleye is to maintain a catch near 6.6 fish/net, with fish longer than 15 and 20 inches ranging from 30-60% and 10-30% of the sample. Walleye catches have alternated between some of the lowest and highest catches in the last five surveys. The fact that the record high Walleye catch in 2013 was preceded and followed by the lowest catches in recent history provides an excellent example of the dynamic nature of fish populations. The 2025 catch of 8.3 fish/net achieved the management goal. The sampled fish ranged from 7.2 to 24.5 inches and averaged 15.5 inches. The management goals for size distributions were also met as 69 and 26% of the sample were longer than 15 and 20 inches. The 2025 survey evaluated a period of annual Walleye fry stocking since 2019 (except for 2020 COVID). Though natural reproduction has been well documented, larger year-classes tend to correspond to years with stocking. Eleven age-classes from age 1 to 21 were observed in the survey. Growth rates for the 2023 and 2024 age-classes were notably slower than prior years. Slower growth for these younger ages may be due to strong year-classes resulting in more competition for food or perhaps in response to the introduction of zebra mussels in recent years. However, growth of older fish remained good. Walleye averaged 14.4 inches after three years of growth, which was similar to the three prior surveys. The population should provide decent fishing based on the number and size of Walleye sampled. The management plan goal for Northern Pike is to maintain a catch of 3.0 fish/net, with 30-60% and 10-20% of the sample longer than 21 and 28 inches. Lower pike numbers are desirable because they tend to have faster growth and better size distributions. Pike catches have varied from 1.0 to 9.3 fish/gill net since 1946. The 2025 catch of 4.4/gill…
