Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

Lake Twenty-One is a small, 28 acre lake located within the Paul Bunyan State Forest in Hubbard County. There is a public access and day-use area with picnic sites on the north shore of the lake. There are DNR maintained primitive campground sites on the east shore and south shore between Lake Twenty-One and Nelson Lake. Lake Twenty-One is susceptible to over-harvest from angling due to its small size, low fertility, and slow growth rates of game fish. Anglers must practice selective harvest if they want to improve or maintain the fishery in Lake Twenty-One. The Minnesota Department of Natural Resources (DNR) has classified Minnesota's lakes into 43 different types based on physical and chemical characteristics. Lake Twenty-One is in lake class 36. Class 36 lakes are small in size and have a large littoral area (area of the lake less than 15 feet in depth). Other class 36 lakes in the Park Rapids management area include Lord, Owl, and Schroeder. Lake Twenty-One provides fishing opportunities for Northern Pike, panfish, and Largemouth Bass. Present and past surveys have shown that Lake Twenty-One supports an abundant Northern Pike population. Sampled Northern Pike had an average length and weight of 23.9 inches and 3.2 pounds, with pike measured up to 29.4 inches. Anglers will find moderate numbers of Largemouth Bass and a very abundant Bluegill and Pumpkinseed population. Bluegill and Pumpkinseed tend to run small in size, with low numbers of fish over 6 inches in length sampled. Bluegills in Lake Twenty-One have slow growth rates when compared to area lakes. Currently no aquatic invasive species (AIS) have been identified in Lake Twenty-One. To avoid spreading AIS, lake users are required to remove all aquatic plants or animals from their watercraft and drain all water from their boat before leaving the access.
