Econfina Creek

The river ends at Deer Point Lake, a reservoir that provides the freshwater supply for Panama City and much of Bay County.

[2][3] Econfina Creek flows through a hilly limestone karst landscape, and there are springs, sinkholes, caves and rock outcrops along the river.

The springs on Econfina Creek are concentrated in a 4.75 miles (7.64 km) long section where the river cuts through the Floridan Aquifer.

"[9] The Florida Department of Environmental Protection recommends that only experienced paddlers use the upper portion of the trail, and advises that the river is too dangerous for paddling when the water is high following heavy rains.

When humans first entered Florida about 12,000 years ago, the water table was much lower, and the course of Econfina Creek was a series of waterholes, and not a flowing river.

[2][7] White settlers started moving into the land along Econfina Creek shortly after the United States acquired Florida in 1821.

The reservoir receives an average of 600,000,000 US gallons (2.3×109 L) a day from four sources, and provides fresh water to Panama City and other parts of Bay County.
