What aquatic invasive species are found in Big McDonald Lake?
Join us in the fight to prevent the spread of invasive species These sneaky creatures can hitch a ride on boats, clinging onto propellers, anchor lines, and trailers. They can even survive in hidden places like bilge water and ballast tanks, or disguise themselves in dirt and sand that sticks to nets, buckets, anchors, and waders. But don't worry, we have the power to stop them in their tracks with just a few simple steps. So let's do our part and protect our waters from these unwanted invaders.
History & Status of the Fishery
Big McDonald Lake is a 935-acre mesotrophic (moderately fertile) lake located in north-central Otter Tail County approximately nine miles west of Perham, MN. Big McDonald Lake is located within the Otter Tail River Watershed. The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. Big McDonald Lake is connected to McDonald (Schwartz) Lake by a navigable channel located along the southeast shoreline. An unnavigable outlet is located along the south shoreline of the lake and connects Big McDonald Lake with Round Lake. The maximum depth of Big McDonald Lake is 46 feet; however, 39% of the lake is less than 15 feet in depth. The secchi disk reading during the 2021 survey was 14.9 feet. Previous secchi disk readings ranged from 9.0 to 13.9 feet.
The north and west shorelines of Big McDonald Lake have been extensively developed. Homes, cottages, and resorts compose the majority of the development. A DNR owned concrete public water access is located off of County Road 35 along the northwest shoreline of the lake. The shoal water substrates consist primarily of sand and gravel. Large stands of hardstem bulrush are located along the west, south, and east shorelines. Areas of common cattail and wild rice are also scattered along the southwest shoreline. Emergent aquatic plants such as bulrush, cattail, and wild rice 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.
Big McDonald 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, Northern Pike, Largemouth Bass, Black Crappie, and Bluegill are the dominant gamefish species present.
The Walleye population continues to be abundant. Several strong year classes are present and should provide good Walleye angling for several years. Walleyes ranged in length from 9.4 to 26.0 inches with an average length and weight of 16.3 inches and 1.6 pounds. Walleyes exhibit excellent growth rates with an average length of 15.2 inches at four years of age.
Northern Pike abundance has remained at a moderate density and age data indicate that natural reproduction continues to be consistently good. Northern Pike ranged in length from 15.2 to 26.9 inches with an average length and weight of 20.1 inches and 1.7 pounds. Pike growth is slow with an average length of 19.2 inches at four years of age.
The Bluegill population is moderately abundant. A quality size structure exists as 26% of the Bluegills were 8.0 inches or greater in length. Bluegills attain an average length of 7.8 inches at seven years of age.
The Largemouth Bass and Black Crappie populations have also been historically abundant with excellent size structures, consistently good reproduction, and average growth.
Anglers can maintain the quality of fishing 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.
Big McDonald Lake was listed as infested with zebra mussels in 2019. 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.
