Overview & Objective(s):
The Everglades Depth Estimation Network (EDEN) supports the restoration of the Everglades by providing scientists and water-resource managers with current water-level and water-depth information for the freshwater part of the greater Everglades. The EDEN water-surface model uses the daily median values of up to 240 of the EDEN water-level gages to generate water-surface maps for the period January 1, 1991 to current. The target users are scientists examining trophic- and landscape-level responses to hydrodynamic changes in the Everglades. Other users include water-resource managers monitoring water levels and depths to meet mandated regulation schedules and wildlife-resource scientists managing habitat requirements for endangered species and other wildlife.

EDEN was initiated in 2006 with funding from REstoration COordination and VERification (RECOVER) Monitoring and Assessment Plan (MAP) program, a component of the Comprehensive Everglades Restoration Plan, through the US Army Corps of Engineers. That funding supports operation and maintenance of 25 (In FY13, reduced to 19 because of funding cuts) gaging stations, data management for daily data of the EDEN network of about 250 (In FY12-13, reduced by about 15-20 because of funding cuts) gages, generation of the daily water-level surfaces, and partial funding for website development and maintenance for public access to the EDEN datasets.

Greater Everglades PES funding allows the project team to explore research topics that would otherwise not be funded by the USACE MAP. In addition, publications and website development are partially funded using PES funds making EDEN findings more broadly available nationwide.

Specific Relevance to Major Unanswered Questions and Information Needs Identified:
As scientists and managers attempt to restore the natural volume, timing, and distribution of sheetflow in the wetlands; consistent, documented, and easily accessible hydrologic data is essential. The EDEN datasets and tools are used to advise policy makers, planners, and decision makers of the potential effects of water management and restoration scenarios of the natural resources of the Everglades. EDEN's real-time data approach coupled with biological models, such as ATLSS and HSIs should help scientists: 1) evaluate how well the simulated relations that drive both biotic and abiotic models reflect and anticipate real-world events; and 2) examine biotic and abiotic responses to hydrodynamic change.

Major accomplishments in FY13 (PES funding plus USACE funding) were:

  1. Real-time, provisional, and final EDEN surfaces are being produced and posted to EDENweb on schedule. Surfaces currently posted on the EDENweb include:
    • Provisional for 10/1/2012 through 6/30/2013
    • Real-time for 7/1/2013 through current
  2. With the support of USGS Greater Everglades Priority Ecosystem Science (GEPES) funds, maintained operation of 19 of the original 25 EDEN-funded gages and 2 coastal water-level gages (originally established for Tom Smith's SET project). Starting 10/1/12, 6 water-level gages funded by EDEN had to be discontinued because RECOVER funding was cut by 30% in FY12.
    • Four gages operated by SFWMD and used by the EDEN surface-water model were discontinued in FY13.
    • One gage was installed by ENP and added to the EDEN network of gages.
  3. Participated in numerous meetings for the 2014 System Status Report (SSR) and generated over 150 graphics using EDEN datasets for review and analysis by the SSR team. Assisted with draft 2014 SSR write-ups for Greater Everglades and Hydrology sections.
  4. Provided quarterly reports (March and June) for water-level monitoring under ERTP at gages and tree islands and continued to maintain access to real-time conditions on EDENweb.
  5. Provided support to several RECOVER principal investigators (PIs) and agencies representatives for EDEN data:
    • Joel Trexler and Chris Catano (FIU) - calculation of ponds for fish sampling data
    • Brad Mueller and Moriah Joy (Seminole Tribe) - information about webpage to monitor water levels under ERTP
    • Gabriela Bucini (Univ. of VT) - provided gage data for ENP
    • Roman Foti (Princeton Univ.) - provided gage and rainfall data for ENP
    • Lori Miller (USFWS) - water depth data for snail kite nesting analysis
    • Chris McVoy (consultant to ENP) - support for EDENapps tools
    • Dan Scheidt (EPA) - water depth data prior to field sampling event
    • Kevin Palmer (USFWS) - impacts of CEPP on water levels in CSSS habitat in ENP
    • David Warfel (Miccosukee Tribe) - EDENapps support and request for training
    • Gina Ralph (USACE) - ENP gage datasets for evaluation of ERTP
    • Matahel Anser (SFWMD) - SPARO gage data
  6. Continued to maintain EDENweb ( to provide data, metadata, and documentation to RECOVER PIs, water-resource managers, and others.
    • The member list for the EDEN newsletter is about 150 and includes participants from federal government agencies (such as DOI, ENP, USGS, FWS, EPA), State agencies (such as SFWMD, FDEP), many local and other universities and several international affiliations.
  7. Coastal EDEN webpages completed and posted to EDENweb, data provided includes:
    • Three parameters for 24 coastal gages
      • Water level
      • Water temperature
      • Salinity
    • Three statistics are computed and plotted
      • Current conditions
      • 7-day average
      • 7-day change
  8. Rainfall and evapotranspiration (ET) data continue to be updated regularly for the EDEN gage network and posted to the EDENweb. Currently, rainfall data is available for 2002 to July 2013 and ET data is available for 1995 to 2012.
  9. EDEN-Syn was developed and tested by users using the prototype application developed in FY12. EDEN-Syn generates synthetic hydrographs for WCA3A South thereby allowing users to create hypothetical hydrologic datasets for use in ecological models.
  10. Initiated development and testing of subarea models for water-level surfacing; may be used to improve daily surfaces and allow for more efficient testing of scenarios by users.
  11. In coordination with the USGS Center for Integrated Data Analytics (CIDA) began development of a graphical interface to allow access to the EDEN database replacing the less versatile USGS NWISweb. Design of Explore and View EDEN (EVE) Version 1 is complete and programming has begun.
  12. Revised two EDENapps tools to provide better user experience and to work with 64-bit machines
    • DataViewer (V2.0.2) was based on the EverVIEW Data Viewer used for viewing model data
    • TransectPlotter (V1.2) was recompiled for 64-bit machines
  13. Developed THREDDS Server to provide easier access to EDEN datasets. Test version shares space with another server in St. Pete USGS office. After testing will be migrated to production server.
  14. Published one and drafted four reports that document aspects of the EDEN project:

Future Planning:

In 2010, the EDEN project was renewed for funding by the USACE (under RECOVER MAP funding) for the period April 2010 through March 2015. The project will continue to create and post daily water-level surfaces on a real-time basis for Everglades investigators.

Recent Products:

In FY13, the EDEN team presented 3 posters and 2 oral presentations at numerous workshops and conferences. The EDEN team published one USGS-series publication and drafting of 4 other reports was initiated. Limited travel approval prevented more extensive workshop and conference attendance in FY13.
