Growing along the banks of the lake are riverine plants such as peach-leaved willow, black willow, bulrush, rose mallow and sandbur. The lake contains fish populations of bass, catfish, crappie and carp. Wildlife such as map turtles, smooth soft-shelled turtles, wintering American bald eagles and a variety of waterfowl are commonly found. The lake continues to provide excellent recreational opportunities. Big Lake is a favorite spot in northwest Missouri for boating and fishing, and a boat launch is available in the park.
Picnic tables dot the shoreline, nestled under cottonwood and walnut trees.
An open picnic shelter with electricity can be reserved for various functions. A swimming pool, with hot showers and a changehouse, is located near the modern two-story motel overlooking the lake. Eight housekeeping cabins along the shore include air conditioning, fireplaces and screened-in porches. Visitors can enjoy eating at the park's restaurant, which offers a scenic view of the lake. In 1989, the Missouri Department of Natural Resources took another step in its mission of preserving the best remnants of Missouri natural landscapes when it purchased almost 300 acres of wetlands adjacent to the lake.
