Jewett Lake is a 737-acre mesotrophic (moderately fertile) lake located in west-central Otter Tail County approximately eight miles north of Fergus Falls, MN. Jewett Lake is located within the Otter Tail River Watershed; however, there are no natural inlets or outlets connected to the lake. The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. The maximum depth of Jewett Lake is 75 feet; however, 36% of the lake is less than 15 feet in depth. The secchi disk reading during the 2022 survey was 22.1 feet. Previous secchi disk readings ranged from 7.1 to 14.4 feet.
The north and east shorelines of Jewett Lake have been extensively developed. Homes and cottages compose the majority of the development. A DNR owned concrete public access is located off of the township road along the north shoreline of the lake. The shoal water substrates consist primarily of sand and gravel. Large stands of hardstem bulrush and common cattail are located along the southwest and southeast shorelines. 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 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.
A large area of hardstem bulrush and common cattail along the southwest shoreline is posted annually as a Largemouth Bass spawning area. A majority of this area is located immediately adjacent to an Aquatic Management Area. Restrictions imposed in the spawning area prohibit fishing or motor boating from ice-out to June 30th, inclusive. Suitable spawning habitat for Largemouth Bass, Bluegill, and Black Crappie in Jewett Lake is primarily limited to this posted spawning area.
Jewett Lake can be ecologically classified as a bass-panfish-Walleye type of lake and this is reflected in the assemblage of the fish community. Walleye, Largemouth Bass, and Bluegill are the dominant gamefish species present.
Walleyes have historically remained very abundant. Walleyes ranged in length from 8.9 to 23.4 inches with an average length and weight of 17.0 inches and 1.7 pounds. Walleyes attain an average length of 15.4 inches at four years of age.
Data from a spring electrofishing assessment indicate that a balanced Largemouth Bass population exists. Age data indicate that Largemouth Bass reproduction is consistently good. Largemouth Bass ranged in length from 9.1 to 17.8 inches with an average length and weight of 14.1 inches and 1.6 pounds. Bass attain an average length of 13.3 inches at five years of age.
Bluegill abundance and size structure have historically fluctuated. Bluegill abundance is presently at a moderate density. Nineteen percent of the Bluegill sample was 7.0 inches or greater in length. Bluegills attain an average length of 7.1 inches at seven years of age.
Anglers can maintain the quality of angling by practicing selective harvest. Selective harvest encourages the release of medium to large-size fish while allowing the harvest of the 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.
Jewett Lake was listed as infested with zebra mussels in 2018. Aquatic invasive species are threatening Minnesota waters. Aquatic invasive 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.
