Florida LAKEWATCH Water Chemistry Summary
Location: Latitude 30°35'38", Longitude 84°14'21"
Period of record: 80 sampling dates; February 23, 1993 to December 17, 1999
Surface area (Shafer et al. 1986): 65 acres / 26 hectacres
Lake Region (Griffith et al. 1997): Tifton/Tallahassee Uplands
Geologic formation (Brooks 1981):
The geology is a mixture of two major types dominated by granular sand and clayey sand with some clay lenses of the Hawthorne Formation and gravel, sand and clay of the Citronelle Formation.
Physiographic region (Brooks 1981):
The water body lies in the Tallahassee Red Hills subdivision of the State Line Hills division of the Ocala Uplift District.
