Bivens Arm is a small shallow lake covering approximately 189 acres (76 ha) in southwest Gainesville.

Bivens Arm is a unique environment, which supports a wide diversity of plant and animal life in an urban setting.

Tumblin Creek, which is fed by small springs and seeps, drains into Bivens Arm and is the primary source of drainage into the lake.

In 1981, the City of Gainesville purchased the land between the lake and Williston Road (SR 331) to form the Bivens Arm Nature Park.

This park features a lush Live Oak Hammock habitat and marshlands, which periodically become inundated with rising water levels from the lake.
