Florida LAKEWATCH Water Chemistry Summary
Location: Latitude 29°27'20", Longitude 82°10'20"
Period of record: 72 sampling dates; September 3, 1993 to November 29, 1999
Surface area (LAKEWATCH): No data available. Bathymetric Map
Lake Region (Griffith et al. 1997): Central Valley
Geologic formation (Brooks 1981):
The geology is dominated by terrace deposits of surface sand over clayey sand and clay with basal deposits of limestone of the preglacial Pleistocene.
Physiographic region (Brooks 1981):
The water body lies in the Alachua Prairies subdivision of the Northern Peninsual Plains division of the Ocala Uplift District.

2 Weights calculated using regressions from Hoyer and Canfield
1994 and from Bill Schaeffer, Florida Fish and Wildlife Conservation Commission
(personal communication).
Catch per unit of effort (kg of fish / hour of sampling) versus total chlorophyll (mg/m3) and number of fish species collected versus surface area of lake for 60 Florida lakes sampled by Canfield and Hoyer (1992) (•) and Lake Orange (Alachua County) electrofishing sampling (o). The lines represent linear regressions for logged values of the 60 Florida lakes.
