What aquatic invasive species are found in Lake Ann?

Ann is a 116-acre lake located in Chanhassen, Carver County. The lakeshore is undeveloped and Lake Ann Park surrounds the majority of the lake. This city-run park includes a concrete boat ramp and fishing pier. Boats are restricted to electric trolling motors only. During high water, the lake is connected to Lake Lucy to the north. Largemouth bass angling is catch-and-release only and there is a 24- to 36-inch protected slot limit for northern pike. All pike within this slot range must be immediately released. One over 36 inches is allowed in possession. A population assessment, including spring electrofishing, was conducted in 2012 to characterize the status of the fish community in Lake Ann.

It appears the 24-to 36-inch slot limit on northern pike that was instituted in 2003 has had a positive effect on the size structure of the population. Gill nets averaged 15.0 pike per set, which is similar to the previous assessment in 2006 (15.5/net), however mean length and weight of pike has increased since 2006. Northern pike averaged 23.8 inches and 3.50 lbs in 2006, compared to 25.3 inches and 3.92 lbs in 2012. In the 2012 population assessment, size structure was skewed towards larger individuals where 81% were 21 inches or longer, 29% were 28 inches or longer, and 2% were 34 inches or longer. The largest pike measured 35.9 inches. Ages 2 through 8 were represented in the sample. Ages 4 and 6 were the most abundant comprising 30 and 25%, respectively. Northern pike grew faster than the statewide average, reaching 21 inches by age 3, and 28.7 inches by age 6.

Nighttime boat electrofishing, targeting largemouth bass, was conducted in May, 2012. Seventy-four largemouth bass were collected at a rate of 40.6 per hour. Bass averaged 10.5 inches and 1.01 lbs, with the largest measuring 19.4 inches and 4.14 lbs. Size structure was large where 41% were 12 inches or larger, and 24% were 15 inches or larger. Ages ranged from 1 to 9, with 30% age 3. Other ages were relatively evenly distributed. Growth was similar to statewide averages. Bass reached 7.6 inches by age 3 and 15.6 inches by age 6.

Bluegill abundance is high in Ann Lake. Catch averaged 69.4 per trap net which is near the 75th percentile compared to other similar lakes lakes. Bluegill numbers have remained consistent over the years averaging 61.2 per trap net from the previous 3 assessments dating back to 1995. Bluegill had a balanced size structure where 55% were 6 inches or longer and 0.5% were 8 inches or longer. Mean length was 6.1 inches and 0.18 lbs with the largest reaching 8.6 inches and 0.44 lbs. Ages ranged from 2 to 8, with the majority (72%) age 4 or 5. Growth was near statewide averages. Bluegill averaged 4.5 inches by age 3 and 7.6 inches by age 6.

In the 2012 population assessment, black crappie abundance was low. A total of 11 were netted. Gill net abundance was below the 25th percentile when compared to other similar lakes. Black crappie abundance is commonly low in Ann Lake, averaging 2.1/gill net in the previous 3 assessments. Fifty percent were greater than 8 inches and the largest measured was 8.6 inches.

Yellow perch abundance was low (2.3/gill net, near the 25th percentile). Perch numbers were higher than the previous assessments in 2006 (0.5/gill net) and 2000 (0.5 /gill net), however considerably lower the historical high of 28.7/gill net in 1995. In 2012, size structure was small; all measured fish were between 5.0 and 7.4 inches.

An assessment of fish in the shallow, nearshore habitats was also conducted using backpack electrofishing and seining. Nine species were sampled which included banded killifish, bluegill, bluntnose minnow, central mudminnow, green sunfish, hybrid sunfish, largemouth bass, northern pike, pumpkinseed, and yellow bullhead. The purpose of the nearshore sampling is to calculate an Index of Biotic Integrity score. An Index of Biotic Integrity (IBI) is estimated based on all fish sampled in this assessment. The absence of sensitive species such as minnows and darters contribute to a low IBI score. In August, Ann Lake scored 74.6 out of a maximum of 160, indicating possible water quality and habitat impairment. In September, the nearshore survey was replicated to look at the repeatability of scores. The second score was 76.4, very similar to the first.
