Florida LAKEWATCH Water Chemistry Summary
Location: Latitude 28°5'20", Longitude 82°35'6"
Period of record: 43 sampling dates; January 13, 1991 to November 23, 1999
Surface area : No data available.
Lake Region (Griffith et al. 1997): Keystone Lakes
Geologic formation (Brooks 1981):
The geology is a mixture of two major types dominated by argillaceous to sandy impure limestone of the Tampa Formation and clastic and shell deposits of the Fort Thompson Group Formation.
Physiographic region (Brooks 1981):
The water body lies in the Land-O-Lakes and Lake Tarpon Basin subdivisions of the Tampa Plain division of the Ocala Uplift District.
