Stocking history
| Year | Species | Size | Number | Pounds |
|---|---|---|---|---|
| 2023 | Walleye | fry | 150,000 | 1.4 |
| 2022 | Walleye | fry | 150,000 | 1.6 |
| 2019 | Walleye | fry | 150,000 | 1.5 |
| 2018 | Walleye | fry | 150,000 | 1.7 |
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.
Round Lake is managed primarily for walleye and smallmouth bass. The current (2014) lake management plan established a long range goal for walleye consisting of a minimum gill net catch of 3.0 fish/set, with some fish over 20 inches present. That plan established a size-based long range goal for smallmouth bass: among smallmouth bass large enough to be taken by anglers (larger than eight inches), at least half must be quality-sized fish (over 12 inches in length). This was the first of three standard surveys scheduled in the 2014 plan to determine the contribution of stocked walleye to the population, and whether the stocking regime used in this lake since 2009 would produce a population meeting the long range goal. Fair numbers of walleye were present in 2015, including some fish larger than 20 inches; however, the long range catch goal for the lake was not met. The 2015 walleye gill net catch was similar to the catch observed in the 2008 survey, prior to the commencement of the current stocking effort. Although the 2015 catch fell within the normal range for a lake of this class, it was fairly low for this lake historically. Five year classes contributed to the 2015 catch. Of the 14 walleye captured, seven came from stocked years, and seven had apparently been produced naturally in years with no stocking. Because walleye can reproduce successfully in this lake, it was likely that some of the walleye from stocked years had also been produced naturally, so the contribution of stocked walleye to the 2015 catch was probably under 50 percent. No strong year classes were evident. Growth of young walleye had been about average, with fish reaching a mean length of 11.0 inches by the end of their third year. The smallmouth bass gill net catch was dominated by a strong group of small three-year-old fish from the 2012 year class. As a result, although the catch was fairly high, the mean weight for fish taken in 2015 was low. Among fish larger than eight inches (nine fish in all), only two (22%) were larger than 12 inches. Growth of young smallmouth bass taken in 2015 had been slow; three-year-old fish had reached a mean length of just 6.1 inches by the end of their third year. Similarly slow growth was observed among the four-year-old fish taken. Northern pike numbers were fairly low in Round Lake in 2015, although similarly low numbers have been seen in several past surveys of this lake. Thanks to the presence of fair numbers of five-year-old fish, and few younger fish, the mean weight for northern pike taken in 2015 was the highest seen to date in this lake.…
