The Hydrological Monitoring Program is responsible for collecting data from a network of monitoring equipment in Lee County's major watersheds.

The network consists of:
  • Recording rain gauges equipped to allow real time access.
  • Stage recorders that record water levels in surface waterways.
  • Monitor wells that record water levels in shallow aquifer.

Currently, the Network consists of approximately 190 shallow monitor wells, 29 recording rain gages, and 12 continuous stage recorders. In addition, the County has a joint agreement with the U.S. Geological Survey (USGS) to operate eight additional continuous stage recorders. The original sole purpose of the Network has been replaced with a multi-objective program. As the database expands, so does recognition of the value of the information. The South Florida Water Management District (SFWMD) is also a great place to get hydrological data.

 Wet Season High Water Table Maps

The Wet Season High Water Table (WSHWT) contour map was developed using data collected from approximately 190 Water Table Aquifer wells throughout Lee County. The current year WSHWT at each well was determined by averaging the two wettest thirty day periods during the wet season. Then, the historical average of WSHWT for each well was calculated using prior years' data.

The following four specific steps are involved:

  • Step 1: Calculate the moving average of the three consecutive groundwater elevations at each well during the current wet season.
  • Step 2: Calculate the average of two highest moving average values determined in Step 1.
  • Step 3: Calculate time average of WSHWT for entire period of record at each well.
  • Step 4: Use the time averaged WSHWTs from the Step 3 to develop the contour map
