Sewell Lake a 338-acre eutrophic (fertile) lake located in south-central Otter Tail County approximately six miles southeast of Dalton, MN. Sewell Lake is part of the Pomme de Terre River Watershed. Land use in the immediate watershed is primarily agricultural. The maximum depth of Sewell Lake is 52 feet; however, 50% of the lake is less than 15 feet in depth. The secchi disk reading during the 2023 survey was 8.5 feet. Previous secchi disk readings have ranged from 4.0 to 17.0 feet. Water clarity in this lake sometimes diminishes during the summer months due to plankton and algae blooms.
A large majority of the shoreline is undeveloped and is primarily composed of agricultural crops. The shoalwater substrates are composed primarily of sand and gravel. A state owned public water access is located along the north shoreline of the lake. Large stands of hardstem bulrush are located along the south shoreline. Common cattail is also prevalent along various shorelines of the lake. Emergent aquatic plants such as bulrush and cattail provide valuable fish and wildlife habitat, and are critical for maintaining good water quality. Emergent plants provide spawning areas for fish such as Northern Pike, Largemouth Bass, and panfish. They also serve as an important nursery area for all species of fish. Because of their ecological value emergent plants may not be removed without a DNR permit.
A special gillnetting survey was conducted to analyze the Northern Pike and Walleye populations.
Northern Pike abundance has decreased over the recent series of surveys. The decline in abundance can be attributed to an outlet structure which was installed in 2016. Resulting lower water levels decreased the amount of available spawning habitat for Northern Pike. Northern Pike ranged in length from 16.5 to 29.6 inches with an average length and weight of 21.8 inches and 2.3 pounds. Northern Pike attain an average length of 23.5 inches at four years of age.
Walleye abundance has remained stable at a moderate level over the recent series of surveys. Walleyes ranged in length from 7.0 to 24.9 inches with an average length and weight of 17.5 inches and 2.2 pounds. Walleyes attain an average length of 12.2 inches at two years of age.
Data from a spring electrofishing survey conducted in 2018 indicated that the Largemouth Bass population is abundant, exhibits consistently good reproduction, fast growth rates, and has a good size structure. A spring electrofishing survey is proposed to be conducted in the spring of 2024 to provide data for an updated analysis of the Largemouth Bass population.
A slot length limit regulation for Largemouth Bass is in effect for Sewell Lake. The regulation is a 14.0 to 20.0 inch protected slot with one over 20.0 inches allowed in possession. The objective of the regulation is to maintain or improve the size structure of the Largemouth Bass population.
Anglers can maintain the quality fishing that this lake has to offer 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 opportunities to catch more large fish in the future.
Sewell Lake is not listed as an infested water. Aquatic invasive species are threatening Minnesota waters. The non-native species can potentially harm water quality, water recreation, aquatic habitat, native species, and fish populations. Anglers can help prevent the introduction and spread of invasive species by following watercraft transportation laws.
