Privately Stocked Fish
* indicates privately stocked fish. Private stocking includes fish purchased by the DNR for stocking and fish purchased and stocked by private citizens and sporting groups.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Fish Consumption Guidelines

These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Status of the Fishery (as of 08/10/2009)

Round Lake was opened to liberalized fishing ten times since 1945, the last time in 1979. A helixor aeration system was installed in 1981. Round was one of four Jackson County creel survey lakes during the 1990 open-water season. Walleye and black bullhead provided most of the catch on Round Lake, with walleyes up to nine pounds.

For many years local residents perceived that Round Lake was too low, the result of Judicial Ditch (J. D). No. 9 diverting much of the lake's natural watershed away to the north and east. As a remedy, a diversion project was proposed during the 1950's and early '60's to pump water back into the lake. Legislative funds were appropriated for that purpose, but for reasons that are unclear, it never happened. After the aeration system was installed, winterkill frequency lessened and interest in higher water levels faded away.

Round Lake has provided considerable angling opportunity over the years for southwest Minnesota, and attracts nonresident anglers as well for walleye, bullhead and channel catfish. Walleye natural reproduction occurs in some years and an experimental spawning reef was placed on the south side of the lake to enhance reproduction. However, the reef has failed to significantly increase walleye natural reproduction success. During the survey in 2001, two smallmouth bass were captured during a seine haul, which indicated possible broodstock in the lake that naturally reproduced. It is possible that with the addition of the spawning reef, spawning habitat for smallmouth bass was adequate for natural reproduction. Despite the fact that channel catfish have not been stocked since 1981, the fishery has done quite well and as a result may be controlling black bullhead relative abundance. Channel catfish may also be utilizing the cavities in the spawning reef for natural reproduction because shoreline seining captured age-0 channel catfish. Even though the reef may have been designed for walleye natural reproduction, it is possible that the reef is having an effect on the total fish community in Round Lake. The fish community composition and size structure, based on the 2001 survey, indicate intensive fish management on Round Lake has provided positive results.

The walleye population in Round Lake is high compared to other similar lakes. The walleye gill net catch rate of 28.3 was higher than what we normally see on lakes like Round Lake. Lengths of walleye sampled in our gill nets ranged from 10.9 to 26.0 inches and averaged 17.3 inches. A high percentage of the fish sampled were in the 16 to 19 inch range.

The yellow perch population is also doing very good in Round Lake. Lengths of yellow perch sampled in our gill nets ranged from 5.8 to 12.6 inches and averaged 10.3 inches.

Black crappie numbers are fairly low in Round Lake but lengths of black crappie are impressive. Black crappie lengths in 2009 ranged from 1.9 to 14.3 inches and averaged 10.1 inches.

Black bullhead numbers remain low in Round Lake. Black bullhead catch rates have not been within the interquartile range since 1990. It is likely the large predator base (walleyes and channel catfish) have reduced black bullhead abundance.

A fair number of northern pike are also roaming the waters of Round Lake. Lengths of northern pike sampled in our gill nets ranged from 15.2 to 21.5 inches and averaged 18.9 inches.

The white bass gill net catch rate of 3.7 fish per net was what we would expect for lakes similar to Round Lake. Lengths of white bass sampled in gill nets ranged from 12.1 to 13.4 inches averaged 12.6 inches. This is the first time white bass have been observed during a lake survey. Another survey first was a 23.2 inch shortnose gar sampled in trap nets during the 2009 assessment.

Channel catfish are quite numerous in Round Lake as well. Although numbers were higher in 2001, catch rates remain respectable. Lengths of channel catfish sampled in gill nets in 2009 ranged from 24.84 to 30.71 inches with a mean length of 27.16 inches. If the walleyes are not eating the bullheads, the larger channel catfish are likely eating them as well.

Other fish sampled during the assessment included common carp, freshwater drum, quillback carpsucker, and white crappie.

To maintain a healthy fishery in Round Lake, we need to promote Best Management Practices (BMPs) within the watershed to help reduce nutrients entering the lake. High nutrients and sediments in a lake can cause algae blooms and reduce water clarity.
