Graphical Plots - Data are collected through automated process and interagency data exchange. Data are provisional and subject to change. The PDF graphical plot version is a higher quality product which requires the free viewer (see note below). PDF graphical plots also allow user to "zoom in".

Graphical Plots in "Portable Document Format (PDF)" require a PDF viewer such as Adobe Acrobat.  Viewer should be loaded on your local computer as a "plugin" to your web browser before you view the documents directly. PDF files may also be downloaded to your PC and you may use the PDF viewer as a stand alone product without the browser.

Free PDF viewer software may be downloaded from Adobe.
