Cradled in valleys surrounded by Osage County's rolling, forested hills, Birch Lake is a perfect setting for nature lovers and other outdoor enthusiasts. The general character of the small lake's shoreline ranges from gentle to steep slopes with numerous sandstone outcrops. The hilltops and upper slopes are generously forested with small hardwood trees, primarily post oak, blackjack oak, hickory, hackberry, and elm. In the damsite area, the terrain is semirugged, with the maximum relief being about 100 feet.
The area's plant life represents a transition zone of the cross timbers forest, oak-hickory forest, tallgrass prairie, and bottom-land plants and shrub. Several species of grasses and numerous colorful flowering species are particularly beautiful in spring and fall.
Two swimming areas are located on Birch Lake. Paid campers are invited to use the area located insde the campground. Visitors exploring the lake just for the day are welcome to use the area located inside Twin Cove on the north side of the lake.
