Florida LAKEWATCH Water Chemistry Summary
Location: Latitude 28°49'54", Longitude 82°18'1"
Period of record: 54 sampling dates; August 23, 1991 to December 21, 1998
Surface area : No data available.
Lake Region (Griffith et al. 1997): Tsala Apopka
Geologic formation (Brooks 1981):
The geology is a mixture of two major types dominated by phosphatic sand, silty sand, and clay of the Hawthorne Formation and limestone consisting of skeletons of fossils in a silt to sand size matrix of the Ocala Limestone Formation.
Physiographic region (Brooks 1981):
The water body lies in the Hernando Hammock and Tsala Apopka Basin divisions of the Ocala Uplift District.
