Wall

Wall Lake is a 683-acre mesotrophic (moderately fertile) lake located in southwestern Otter Tail County approximately five miles east of Fergus Falls, MN. Wall Lake is part of the Otter Tail River Watershed. An unnavigable outlet is located along the west shoreline of the lake which is a tributary to the Otter Tail River. The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. The maximum depth of Wall Lake is 34 feet; however, 33% of the lake is less than 15 feet in depth. Historical Secchi disk readings range from 4.1 to 14.3 feet. A majority of the shoreline of Wall Lake has been developed. The development consists primarily of homes and cottages. A DNR owned concrete public water access is located along the north shoreline. The shoal water substrates consist primarily of sand and gravel. Large stands of hardstem bulrush are prevalent throughout the lake. Emergent aquatic plants such as hardstem bulrush provide valuable fish and wildlife habitat and are critical for maintaining good water quality. They protect shorelines and lake bottoms and can 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 an important nursery area for all species of fish. Because of their ecological value, emergent plants may not be removed without a DNR permit. Because of its proximity to Fergus Falls, Wall Lake is a popular angling lake during both the open water and ice fishing seasons. Wall Lake is a good all-around fishing lake with most gamefish species having abundant populations and good size structures. Northern Pike abundance has been trending upward in recent surveys. Northern Pike ranged in length from 17.1 to 31.5 inches with an average length and weight of 23.4 inches and 2.9 pounds. Northern Pike growth is fast with an average length of 26.3 inches at four years of age. Walleye abundance is moderate. The 2019, 2021, and 2024-year classes should provide consistently good Walleye angling for several years. Walleyes ranged in length from 8.2 to 26.3 inches with an average length and weight of 19.6 inches and 2.9 pounds. Walleyes attain an average length of 16.3 inches at four years of age. MN DNR Fisheries sustains a viable Walleye population by stocking Walleye fingerlings two out of every three years. A spring electrofishing survey was conducted to analyze the Largemouth Bass population. Catch and length data indicate that a balanced Largemouth Bass population exists. Age data indicate that Largemouth Bass reproduction is consistently good. Largemouth Bass ranged in length from 5.4 to 20.0 inches with an average length and weight of 13.9 inches and 1.7 pounds. Largemouth Bass attain an average length of 13.9 inches at five years of age. A reduced daily bag limit regulation for sunfish (10 per day) was implemented in 2021. The objective of the regulation is to maintain the quality of the Bluegill size structure. A spring trap netting survey was conducted in 2025 to collect data on the Bluegill population. This was the second survey specifically targeting Bluegill on Wall Lake. Bluegills are abundant, but length data from this survey indicates that quality-size fish are not. Age data suggests that Bluegill reproduction has been consistently good in recent years. Bluegills ranged in length from 3.3 to 8.5 inches in length with 21% of the fish measuring 7.0 inches or greater. Bluegills attain an average length of 7.6 inches at seven years of age. Anglers can maintain the quality of fishing by practicing selective harvest. Selective harvest encourages the release of medium to large fish while allowing the harvest of more abundant smaller fish for table fare. Releasing the medium to large fish will ensure that 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. Wall Lake was listed as infested with Zebra Mussel in 2023. 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.

The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. The maximum depth of Wall Lake is 34 feet; however, 33% of the lake is less than 15 feet in depth. Historical Secchi disk readings have ranged from 4.1 to 9.0 feet. A majority of the shoreline of Wall Lake has been developed. The development consists primarily of homes and cottages. A DNR owned public water access is located along the north shoreline. The shoal water substrates consist primarily of sand and gravel. Large stands of hardstem bulrush are prevalent throughout the lake.

This was the second survey specifically targeting Bluegill on Wall Lake. Bluegill are abundant, but data from this survey indicates quality fish are not. Age data suggests that Bluegill recruitment has been fairly consistent in recent years. Fish sampled ranged in size from 3.3 to 8.5 inches in length, with 21% of the Bluegills measuring 7.0 inches or greater. Bluegills attain an average length of 7.6 inches at seven years of age.

A special gillnetting assessment was conducted to analyze the Northern Pike and Walleye populations. A moderate density Northern Pike population exists. Age data indicate that Northern Pike reproduction is consistently good. Northern Pike ranged in length from 13.2 to 33.9 inches with an average length and weight of 20.7 inches and 2.2 pounds. Pike attain an average length of 24.5 inches at four years of age. The Walleye population is also of a moderate density. The 2018 and 2019 year classes of Walleyes are strong and should provide consistently good angling for several years. Walleyes ranged in length from 8.7 to 26.0 inches with an average length and weight of 17.0 inches and 2.0 pounds. Walleyes attain an average length of 14.2 inches at three years of age. Catch and length data indicate that a balanced Largemouth Bass population exists. Age data indicate that Largemouth Bass reproduction is consistently good. Bass ranged in length from 10.2 to 18.5 inches with an average length and weight of 13.0 inches and 1.3 pounds. Largemouth Bass attain an average length of 13.7 inches at five years of age. The 2018 year class of Black Crappies is very strong and should provide excellent crappie angling opportunities for several years. Black Crappies ranged in length from 5.4 to 12.6 inches with a mean length of 8.1 inches. Crappies attain an average length of 9.2 inches at four years of age.
