History & Status of the Fishery
Lake Twenty-One is a 122-acre mesotrophic (moderately fertile) lake located in northwest Otter Tail County approximately five miles east of Erhard, MN. The immediate watershed is composed of mixed hardwood forest and grassland. Shoreline length is 3.8 miles. The maximum depth is 47 feet and 41% of the lake is 15 feet or less in depth. The secchi disk reading during the 2010 lake survey was 18.5 feet. Previous secchi disk readings have ranged from 9.0 to 23.0 feet.
Lake Twenty-One is located within Maplewood State Park. The lakeshore remains entirely undeveloped except for one small private cabin. An undeveloped, carry-in public water access is located along the southwest shoreline of the lake. Shoal water substrates consist primarily of sand and gravel. Stands of hardstem bulrush are scattered along the entire shoreline of the lake.
Special fishing regulations are in effect on Lake Twenty-One. The daily bag limit for sunfish is ten and the daily bag limit for black crappies is five. All largemouth bass and northern pike must be immediately released. The objective of these regulations is to improve the size structure of these species.
Lake Twenty-One can be ecologically classified as a bass-panfish type of lake and this is reflected in the assemblage of the fish community. Northern pike, largemouth bass, black crappie, and bluegill are the dominant species in the fish community. The prolificacy of these species can be attributed to the abundance of suitable spawning habitat that is available.
A high-density northern pike population exists. The northern pike test-net catch rate was the highest recorded for this lake. Age data indicate that northern pike reproduction is consistently good. Pike ranged in length from 11.7 to 32.7 inches with an average length and weight of 18.7 inches and 1.6 pounds. Northern pike attain an average length of 23.2 inches at four years of age.
The bluegill population is moderately abundant. Bluegill size structure is very good with 68% of the bluegills in the trap net sample measuring 7.0 inches or greater in length. Bluegills attain an average length of 6.6 inches at six years of age.
Data from a spring trapnetting assessment indicate that the black crappie population is abundant and it exhibits a very good size structure. Seventy-two percent of the black crappies were 10.0 inches or greater in length. Crappies attain an average length of 10.1 inches at five years of age.
Data from recent assessments indicate that a balanced largemouth bass population exists. Bass ranged in length from 8.3 to 17.2 inches. Largemouth bass attain an average length of 13.2 inches at five years of age.
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 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.
