Florida LAKEWATCH Annual Data Summaries 2004 presents limnological data collected from 607 lakes, 127 river/creek stations, 4 springs, and 142 saline stations sampled by Florida LAKEWATCH citizen volunteers during 2004 (Figure 1). More than 1500 Florida volunteers have monitored 880 water bodies and saline or offshore stations monthly in almost 50 counties.

This is the thirteenth annual Florida LAKEWATCH report in which Florida LAKEWATCH data are summarized and compiled. This years report contains a comprehensive summary of Florida LAKEWATCH water chemistry data collected during 2004. The aquatic plant surveys completed in 2003 and 2004 are also included for any water body that was sampled during 2004. A dot (.) recorded on a line indicates that no information was collected. The information contained in this report includes the following summaries when available:

1) Florida LAKEWATCH water chemistry summary (880 summaries)

a) Location of water body (Latitude and Longitude)
b) Period of record of sampling
c) Surface area (Dickinson et al. 1982, Shafer et al. 1986, or Florida LAKEWATCH bathymetric maps)
d) Florida Lake Region (Griffith et al. 1997)
e) Geologic (Brooks 1981 a) and physiographic regions (Brooks 1981b) Long-term, 2004 monthly, and 2004 yearly Florida LAKEWATCH averages for total phosphorus, total nitrogen, chlorophyll, and Secchi depth
g) Periodic water chemistry data: quarterly color for freshwater and monthly color and specific conductance for saline stations
h) Supplemental water chemistry data: pH, total alkalinity, specific conductance, color, chloride, silicon, sulfate, calcium, magnesium, sodium, potassium and iron

2) Florida LAKEWATCH aquatic plant summary (39 summaries in 2003 & 34 summaries in 2004):

a) Percent area covered by aquatic macrophytes; (PAC)
b) Percent volume infested with aquatic macrophytes (PVI)
c) Above-ground standing crop of emergent, floating-leaved, and submerged vegetation (kg/m2)
d) Average width (m) of the floating-leaved, and emergent zones
e) Average lake depth (m) All plant species seen while sampling, listed according to the frequency of occurrence in evenly spaced transects around the water body

This information is available thanks to the hundreds of LAKEWATCH volunteers who are sampling their lakes every month.
