Anna Lake is a 538-acre mesotrophic (moderately fertile) lake located in south-central Otter Tail County approximately four miles north of Underwood, MN. The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. The maximum depth is 55 feet; however, 69% of the lake is 15 feet or less in depth. The secchi disk reading was 7.0 feet. Previous secchi disk readings have ranged from 4.0 to 9.3 feet.
The majority of the shoreline of Anna Lake remains undeveloped. A DNR owned concrete public access is located along the southwest shoreline. Shoal water substrates consist primarily of sand and gravel. Hardstem bulrush and common cattail are prevalent along the shoreline of the entire lake. Emergent aquatic plants such as bulrush and cattail provide valuable fish and wildlife habitat, and are critical for maintaining good water quality. They protect shorelines and lake bottoms, and can actually absorb and break down polluting chemicals. Emergent plants provide spawning areas for fish such as Northern Pike, Largemouth Bass, and Panfish. They also serve as important nursery areas for all species of fish. Because of their ecological value, emergent plants may not be removed without a DNR permit. To maintain the excellent water quality and angling that this lake has to offer, it is imperative to preserve the quality of the aquatic habitat.
Anna Lake can be ecologically classified as a Bass-panfish type of lake and this is reflected in the assemblage of the fish community. Largemouth Bass, Black Crappie, and Bluegill are the dominant game-fish species. The prolificacy of these species can be attributed to the abundance of suitable spawning habitat that is available.
A spring electrofishing assessment was conducted to analyze the Largemouth Bass population. Data indicate that Largemouth Bass are abundant and that the population is well balanced. Bass ranged in length from 4.6 to 16.0 inches with an average length of 11.1 inches. Bass attain an average length of 14.3 inches at five years of age.
Data collected from a spring trapnetting assessment indicate that Black Crappies are very abundant. The 2009 and 2010 year classes are strong and should provide consistently good Black Crappie angling for several years. Sixty-six percent of the crappies sampled were 10.0 inches or greater in length. Crappies attain an average length of 11.1 inches at five years of age.
Bluegill abundance tends to fluctuate due to inconsistent levels of reproduction. Twenty-two percent of the Bluegills were 7.0 inches or greater in length. Bluegills attain an average length of 6.3 inches at five years of age.
Walleye abundance is at a historical high for this lake. Walleyes ranged in length from 10.3 to 21.9 inches with an average length and weight of 14.5 inches and 1.1 pounds. Walleyes attain an average length of 14.5 inches at four years of age.
Anglers can maintain or improve the quality of angling by practicing selective harvest. Selective harvest encourages the release of medium to large size fish while allowing the harvest of more abundant smaller fish for table fare. Releasing the medium to large fish will ensure that the lake will have enough spawning age fish on an annual basis and will provide anglers with more opportunities to catch large fish in the future.
