History & Status of the Fishery
McMahon (Carl's) Lake is a productive 110-acre, Class 43 lake. It is located 6 miles south of the city of Prior Lake, in Credit River Township. The lake is primarily managed for Bluegill and Largemouth Bass, and secondarily managed for Northern Pike, Walleye, and Yellow Perch. The New Market Sportsman's Club stocks Walleye. A Standard Survey was conducted in 2015 to assess the gamefish populations.
Bluegill abundance was high in 2015; the catch rate of 24.3 fish per trap net exceeded the third quartile for this Lake Class. The average size of trap-netted Bluegill was 6.1 inches and 0.19 pounds. Thirty-four percent of the fish exceeded 7 inches, and only 2% of the fish exceeded 8 inches. The largest Bluegill was 8.5 inches and 0.45 pounds. Bluegill attained an average length of 6.6 inches by age 3, and 7.3 inches by age 4.
Walleye abundance is relatively high compared to other lakes in the West Metro Fisheries Area. The 2015 catch rate of 4.0/gill net fell between the first quartile and median for Class 43 lakes throughout the state. This is a decline from the 2010 catch rate of 6.0 fish per gill net. Walleye mean length and weight were 19.7 inches and 2.74 pounds, with the largest reaching 26.0 inches. Size structure revealed a population of large individuals, with 92% of fish exceeding 15 inches, 54% at 20 inches or longer, and 8% at 25 inches or longer. Walleye reach an average of 15.7 inches by age 4, and 22.0 inches by age 6.
Northern Pike were abundant in 2015. The gill net catch rate (11.7/net) exceeded the 75th percentile for class 43 lakes. This decrease in catch from the previous survey (in 2010), when 15.3 fish per net were caught, is also accompanied by an improved size structure since that survey. In 2015, the average Northern Pike was 22.0 inches and 2.58 pounds, an increase from an average size of 20.6 inches and 1.97 pounds. Fifty-seven percent of the 2015 catch exceeded 21 inches, compared with 39% of fish exceeding 21 inches previously. Eleven percent of Northern Pike exceeded 28 inches in 2015, compared with 6% exceeding 28 inches in 2010. The largest fish measured in 2015 was 33.7 inches and 9.35 pounds. The fish reached an average of 20.7 inches by age 3, and 27.2 inches by age 7.
Black Crappie abundance was high in gill nets (17.7, above third quartile) and moderately high in trap nets (5.2, between median and third quartile). For both gear types combined, 36% of Black Crappie were 8 inches or longer and the largest fish sampled was 10.6 inches and 0.68 pounds. Average size was 7.3 inches and 0.24 pounds.
In 2015, Yellow Perch were moderately high in abundance (20.0/gill net, between median and third quartile) compared with other Class 43 lakes in the state. Mean length and weight were 7.2 inches and 0.18 pounds. Eighteen percent were 8 inches or longer and the largest fish was 10.2 inches and 0.61 pounds.
Other species sampled in low abundance included Black Bullhead, Brown Bullhead, Golden Shiner, and Largemouth Bass.
