Black Bear Lake is a fair distance from any major roads and the long access road in probably discourages many non-local anglers from fishing this lake. Development on the lake is restricted to the north and south ends of the lake, while State and County land preserves much of the lake as undeveloped. The aquatic plant community, which grew to a depth of 18 feet in 1998, is fairly diverse. These plants are extremely important to maintaining a healthy aquatic environment. Emergent plants, like bulrush, cattail and wild rice, which are quite numerous, are important for shoreline protection, regulating nutrient levels, and they provide essential spawning habitat for northern pike, bass and panfish. Submerged plants provide food and cover needed by fish and other aquatic species.
The two most abundant species in 2010 were largemouth bass, which were sampled by electrofishing, and tullibee (cisco). Both were caught in high numbers. Average size of the bass was 11.5" and 43% were 12" or larger. Tullibees are an important forage fish for the northern pike in the lake. Average size of the tullibee was 12.4". Even with abundant tullibee, the northern pike population was just average and size was on the small side, with an average length of only 18.6". Black crappies, which were seen in decent numbers while electrofishing for bass in the spring, weren't sampled well in nets.
Other fish species sampled included bluegill, bowfin (dogfish), brown bullhead, green sunfish, hybrid sunfish, pumpkinseed, rock bass, white sucker, yellow bullhead, and yellow perch. Various minnow species were also sampled while backpack electrofishing and seining, including a pugnose shiner, which is a species of concern.

Recreational activities such as recreational boating, angling, waterfowl hunting, and diving may spread aquatic invasive species. Some aquatic invasive species can attach to boats, while others can become tangled on propellers, anchor lines, or boat trailers. Many species can survive in bilge water, ballast tanks, and motors or may hide in dirt or sand that clings to nets, buckets, anchors, and waders. Fortunately, completing simple steps can prevent the transport of aquatic invasive species.
