Lake Aurora is a freshwater lake located in eastern Polk County, Florida. The lake is approximately 9 miles (14 km) east of Lake Wales on State Road 60. While not a very big lake, the lake is relatively deep compared to other central Florida lakes with an average depth of 12 ft (3.7 m) and a maximum depth of 45 ft (14 m). The depth of the lake as well as its crystal blue waters indicate that the lake was probably once a sinkhole which filled with water. The lake is in an area east of the Lake Wales Ridge dominated by scrub oak with occasional sandspur clearings.
