Lake Jackson is a shallow, prairie lake on the north side of Leon County, Florida, United States, near Tallahassee, with two major depressions or sinkholes known as Porter Sink and Lime Sink.

The lake is located in the Red Hills Region, and has fluctuated from periods of being dry to a maximum elevation of 96 feet (29 m) above sea level. The lake is approximately 7.5 miles (12 km) long and its area is 6.2 square miles (16 km2). There is no outflow from streams or runoff.

Geography [ edit ]

Interstate 10 runs across the southern tip of the lake.

Geology [ edit ]

Karst [ edit ]

Drainage [ edit ]

Water drains from the lake into the Floridan Aquifer through the sinkholes. These are usually partially or completely plugged with sediments, but collapse when groundwater levels drop[citation needed], allowing lake water to funnel into the aquifer, which can completely drain the lake. Early 1840 newspapers report the lake drained empty. The lake also drained on September 16, 1999.[1] On May 10, 2007, the lake flowed down the Porter Sink, but pools of water still remained.[2]
