Annie Battle

Annie Battle Lake is a 334-acre mesotrophic (moderately fertile) lake located approximately five miles northeast of the town of Battle Lake, MN. An unnavigable inlet from Molly Stark Lake is located along the southwest shoreline. An unnavigable outlet along the northwest shoreline flows into Blanche Lake. The immediate watershed is composed of rolling grassland interspersed with hardwood woodlots. The maximum depth is 51 feet; however, 45% of the lake is 15 feet or less in depth. The shoreline length is 2.7 miles. The Secchi disk reading during the 2019 survey was 6.3 feet. Previous Secchi disk readings ranged from 8.5 to 14.5 feet. The entire shoreline of Annie Battle Lake is located within Glendalough State Park; therefore, development along the lakeshore is very limited. There is a campground located on the northwest shoreline with four rental cabins and several campsites. Primitive camping sites are also located along the east shoreline. A carry-in water access is also located along the northwest shoreline. Shoal water substrates consist primarily of sand and gravel. Hardstem bulrush is prevalent along the entire shoreline. Emergent aquatic plants provide valuable fish and wildlife habitat and are critical in maintaining good water quality. They protect shorelines and lake bottoms from wave erosion and help absorb excess nutrients. Emergent plants also provide critical spawning habitat for several fish species including Northern Pike, Largemouth Bass and panfish. They also serve as important nursery areas for many species of fish. Because of their ecological value, emergent plants cannot be removed without a DNR permit. Prior to 1990, there was no public access to Annie Battle Lake. When Glendalough State Park was established in 1990 and public access was allowed to the lake, angling pressure was extensive, which negatively impacted the quality fishery that existed. In an attempt to re-establish the quality of the fish populations, Annie Battle Lake was closed to angling from 1993 to 1997. In 1997, special regulations were implemented which designated the lake as a "heritage fishery" in which electronic equipment (depth finders, GPS units, etc.) and motors of any type, including power augers, were prohibited. The regulation also includes catch and release angling for Largemouth Bass and Northern Pike and a reduced bag limit for Bluegill and Black Crappie (5 each per day). The intent of this regulation is to improve and/or maintain the size structure of these species. Annie Battle Lake can be ecologically classified as a bass-panfish type of lake and this is reflected in the assemblage of the fish community. Bluegill, Largemouth Bass and Black Crappie are the dominant fish species in Annie Battle Lake. The prolificacy of these species can be attributed to the abundance of suitable spawning habitat that is available. A spring trap netting survey was conducted in 2025 to collect data on the Bluegill population. This was the first survey specifically targeting Bluegill on Annie Battle Lake. Bluegill are abundant and quality fish are present as well. Age data indicates that Bluegill recruitment has been inconsistent in recent years. Fish sampled ranged in size from 3.2 to 8.7 inches in length, with 69% of the Bluegills measuring 7.0 inches or greater. Bluegills attain an average length of 7.4 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. Annie Battle 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.

A spring electrofishing survey was conducted to analyze the Largemouth Bass population. Survey data indicate that Largemouth Bass abundance, growth, and reproduction occur at moderate levels. Largemouth Bass ranged in length from 6.8 to 16.8 inches with an average length of 12.8 inches. Largemouth Bass attain an average length of 12.7 inches at five years of age.

Bluegill, Largemouth Bass and Black Crappie are the dominant fish species in Annie Battle Lake. The prolificacy of these species can be attributed to the abundance of suitable spawning habitat that is available. A low-density Northern Pike population exists. Northern Pike ranged in length from 13.9 to 32.2 inches with an average length and weight of 18.1 inches and 2.2 pounds. Pike attain an average length of 19.4 inches at four years of age. Bluegill size structure is excellent with 60% of the sample measuring 7.0 inches or greater in length and 9% measuring 8.0 inches or greater in length. Bluegills attain an average length of 7.0 inches at six years of age. The reduced bag limit may be having a positive influence on the size structure of the Bluegill population. Data collected from a spring electrofishing assessment indicate that a balanced Largemouth Bass population exists. Age data indicate that Largemouth Bass reproduction is consistently good. Bass ranged in length from 8.2 to 17.3 inches with an average length and weight of 13.0 inches and 1.3 pounds. Largemouth Bass attain an average length of 14.3 inches at six years of age. The Black Crappie population is moderately abundant. Black Crappie ranged in length from 5.4 to 12.2 inches with an average length of 9.4 inches. Forty-three percent of the crappies were 10.0 inches or greater in length. Crappies attain an average length of 9.1 inches at five years of age. Walleyes ranged in length from 14.7 to 23.5 inches with an average length and weight of 17.6 inches and 1.8 pounds. Walleyes attain an average length of 14.7 inches at five years of age.
