Bass Lake is located approximately 6 miles south of Biwabik. There is a concrete plank boat ramp with a small parking lot located near the NE corner of the lake for public access. Bass is a highly developed lake with numerous homes and cabins surrounding the shoreline. Sandy substrates with aquatic plants are commonly found near shore.
Ten species of fish were sampled in 2015 by gill netting, trap netting and night electrofishing. Northern pike, largemouth bass, bluegill and black crappie were most common. Yellow bullhead were common in the trap net catch. Although Bass was stocked with walleye fingerlings up until 2010, only one walleye was sampled in 2015.
Northern pike numbers were average compared to other similar area lakes and similar to past surveys on this lake. Northern pike were generally small on the lake, averaging about 20 inches long. This is smaller than the long term average of 23.2 inches. Anglers are encouraged to keep the smaller average size pike and release the larger ones, which could help improve the overall size range of pike.
Largemouth bass were common in the electrofishing sample. This catch rate was more than three times the goal of 15.0/hr in the management plan for Bass Lake. The average largemouth sampled was 12.2 inches and the largest was 17.5 inches long. Sixty percent of the largemouth sampled by electrofishing were 12 inches or larger.
Bluegill numbers were slightly above average compared to similar lakes, however abundance was much lower than in past surveys. Bluegill on Bass lake are very slow growing. The average bluegill sampled was about 7 inches long and 9 years old. The largest bluegill sampled was 8.5 inches long.
Black crappie abundance was above average compared to other similar area lakes but slightly less than in past surveys. Crappie were generally on the small size mostly ranging from 4 to 9 inches. Crappie fishing can vary widely from year to year as is typical with a fish species that has boom and bust cycles. There is often only one or two year classes in the fishery at a time, so anglers typically see that the fish are mostly only one or two general sizes.
