Ground-water conditions in southern Florida


Production of site imagemaps

The maps are based upon analysis of the real-time water-level monitoring sites that are on the USGS Center for Water and Restoration Studies cooperative data-collection program. This set is further restricted to those sites that have had water-level data transmitted within the past 120 days. For the remaining sites, the following data are also retrieved from the project database:

  1. County in which the monitoring site is located,
  2. Water-supply system monitored by the site (aquifer for wells),
  3. Whether it is a potential drought indicator,
  4. Latest available 7-day averages of daily water levels at the sites, and
  5. De-trended frequency statistics for the current week.

In addition to a large-area map showing the selected sites in South Florida, maps for each county, major aquifer, and the surface-water system are generated. The symbols for each site are determined by the type of monitoring system at the site, whether the site has recent data, and by comparing the 7-day running average of the stored daily values to the frequency statistics for the week of the year.

Basis of computations:



Funding for the USGS to design and maintain this site has been provided through a cooperative agreement with the South Florida Water Management District (SFWMD). Water-level conditions are monitored by the USGS with support from Federal, State, and local cooperators.
