Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

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 07/12/2010)

Lotus is a 246-acre lake located in Chanhassen in Carver County. It is primarily managed for walleye and largemouth bass. A fish population assessment was conducted during mid-July 2010 to determine the size structure and abundance of game fish species in the lake. The walleye population density in Lotus Lake has been stable over the last two assessments. Walleye density is moderate (3.3/gill net) and unchanged from the previous assessment in 2004 (3.3/gill net). Eighty-five percent were 10 inches or greater, 75% were 15 inches or greater, and 10% were 20 inches or greater. Mean length and weight in the gill nets were 15.4 inches and 1.4 lbs, with the largest measuring 22.9 inches. Walleye ranged in age from 1 to 7. The strongest year class was the 2006 cohort (age 4), which comprised 59% of the sample. Walleye reached 15 inches by age 3 and 20 inches by age 5.

The bluegill population, like the walleye population, has remained stable over the last two assessments. Bluegill abundance is moderate (25.4/ trap net), similar to the previous assessment in 2004 (25.0/ trap net). Sixty-four percent were 6 inches or greater and the largest measured 7.4 inches. Mean length and weight were 5.8 inches and 0.17 lbs. Bluegill ranged in age from 1 to 7, 61% were age 5 and 19% were age 4. Bluegill averaged 6 inches by age 4.

Black crappie abundance is moderately low compared with similar lakes in the state. Gill net catch has dropped by 74%, from 12.8/net in 2004 to 3.3/net in 2010; however, 2010 trap net catch (1.1/net) has remained similar to 2004 (2.0/ net). Based on gill net catch, 60% of black crappie were 8 inches or greater, and the largest measured 8.9 inches. Mean length and weight were 7.7 inches and 0.24 lbs. Ages 1 to 5 were represented, with the 2007 (age 3) and 2008 (age 2) year classes each comprising 34% of the sample. Black crappie averaged 8 inches by age 3.

Yellow perch abundance appears to be decreasing, from a high of 181/gill net in 1999 to a low of 4/gill net in the 2010 assessment. Compared to other similar lakes, 4/ gill net is considered low. Mean size (0.13 lbs) has improved over the previous assessments; however it is average compared to other similar lakes. All yellow perch sampled were between 6 and 8.3 inches, averaging 7.1 inches. Eighty-five percent were age 4 or 5, the remaining 15% were age 3. Yellow perch reached 8 inches by age 5.

Passive sampling gears, such as trap nets and gill nets, are not effective methods for collecting largemouth bass, so the data presented in these nets for this species is not indicative of relative abundance. Electrofishing is the typical method for largemouth bass assessments but was not conducted during this survey. Two largemouth bass were sampled at 4.4 and 17.4 inches.

Similar to previous assessments, northern pike abundance is low (0.3/gill net). The two captured were 20.9 inches and 24.7 inches. Other species sampled in low abundance were brown bullhead, golden shiner, hybrid sunfish, pumpkinseed, greens sunfish, and yellow bullhead.
