Little Blueberry is located in eastern Becker County, seven miles southeast of Osage. Little Blueberry has a surface area of 69 acres and a maximum depth of 47 feet. There is a county access with an earthen ramp on the north shore of the lake. Little Blueberry provides fishing opportunities for northern pike, panfish, and largemouth bass. Due to its small size, Little Blueberry is very susceptible to over-harvest. Anglers must practice selective harvest if they want to maintain or improve the fishery in Little Blueberry.
The Minnesota Department of Natural Resources (DNR) has classified Minnesota's lakes into 43 different types based on physical, chemical, and other characteristics. Little Blueberry is in lake class 28. Other area lakes in this same classification include: Big Bass, Dinner, Emma, Gilmore, Indian, Nagel, Newman, Thomas, and Williams.
Northern pike abundance (1.5 pike/gillnet) was down from past surveys and below the range "typical" for this lake class. Past surveys have shown the northern pike population to be dominated by small, "hammer handle" pike, with an occasional large fish. Little Blueberry has good panfish populations, composed of black crappie, bluegill, and pumpkinseed. Anglers will find bluegill and pumpkinseed in the 6-8 inch size range. Black crappie abundance (0.8 black crappie/trapnet) was down from past surveys. Largemouth bass are present and were sampled in moderate numbers with standard survey gear. Largemouth bass up to 18.0 inches were sampled. Yellow perch were sampled in moderate numbers with fish measured up to 11.1 inches. Walleye were not sampled in 2010, but have been sampled in past surveys in very low numbers. Other species sampled included moderate numbers of bowfin (dogfish), and low numbers of black, brown, and yellow bullhead.
