During the planning process, many datasets were developed to feed the analysis necessary for the Muddy Creek comprehensive watershed plan. Data from various sources were compiled and are provided below in case they are needed for future analysis or dissemination.

GIS data

GIS (geographic Information systems) is an integral tool for developing a watershed-based plan. Many datasets can be summarized and overlaid on various spatial features. The datasets listed below were used in the planning and analysis process. These GIS layers can be viewed for free with the ArcGIS Explorer  software program. Also, additional data can be downloaded through the WVGIS Technical Center.


A spatial database was created that contains all the GIS data layers used during the Muddy Creek planning project. A list of the data layers are detailed in the summary document and highlighted below.

  • Hydrology
  • Land use (2001)
  • Karst features, including dye tracing
  • Septic analysis results
  • Parcels with ownership information
  • Proposed agricultural project sites
  • Structures in the riparian zone
  • Water monitoring sites and lab data
  • Water quality analysis results and metrics by reachshed
  • Soil data
  • Roads
  • All TMDL-specific datasets with load allocations (provided by TetraTech)
  • 30-meter elevation and hillshade grids
  • Greenbrier watershed topographical map (provided by TetraTech)

A series of Google Earth files was created to highlight some of the major data deliverables for this project. These files are listed below by category and are shown on the mapping pages of this website.  In order to view these files, you will need to install Google Earth on your computer.

  1. Hydrology and Water Quality
  2. Land Ownership and Use
  3. Project Priorities
    1. Septic Project Priority
    2. Agricultural Project Priority

Water quality data

An Access database was created to house all the water sampling data collected by WVDEP for the Greenbrier River watershed, from 1999-2009. The Muddy Creek monitoring locations are listed in the database, and a query has been developed to show all the fecal coliform results in the Muddy Creek watershed over this time period; a chart summarizing this dataset is shown below. The database contains analysis results for many different parameters at each of the sample locations.

TMDL data and reports

Listed below and available for download are the GIS data provided with the Greenbrier River TMDL data CD, which was developed by Tetra Tech.

The Greenbrier River TMDL technical report provides a series of spreadsheet appendices, which help with various calculations necessary to determine restoration efforts.  Also listed below are the actual reports prepared by Tetra Tech and approved by USEPA.

Shown in these maps are the water quality improvement priority areas for both septic and agricultural projects. For more information about these priority areas please review the watershed-based plan or explore the results through our mapping application.
