Birch Lake is located on Birch Creek in Osage County, Oklahoma. The dam site is at mile 0.8 of Birch Creek approximately one and one half miles south of the town of Barnsdall and about 20 miles southwest of the city of Bartlesville.
Birch Lake offers several excellent outdoor recreational opportunities for year-round enjoyment of the project.
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.
