Florida LAKEWATCH Water Chemistry Summary
Location: Latitude 29°38'53", Longitude 82°3'3"
Period of record: 119 sampling dates; December 3, 1989 to December 20, 1999
Surface area (LAKEWATCH): 277 acres / 112 hectacres Bathymetric Map
Lake Region (Griffith et al. 1997): Trail Ridge
Geologic formation (Brooks 1981):
The geology is a mixture of two major types dominated by deeply weathered clayey sand and granular sand and quartz sand and quartzite gravel with sandy clay beds of the Hawthorne Formation.
Physiographic region (Brooks 1981):
The water body lies in the Interlachen Sand Hills division of the Central
Lake District.
