A Watershed Information System (WIS) has been developed that contains a set of stand-alone,
geographic information system (GIS)-based tools for the analysis and visualization of watershed
data including water quality, stream flow, land use, and other watershed based data sets. The WIS
software is designed to provide users with the ability to analyze existing data in order to make
decisions in watershed management and in the development of TMDLs. The WIS is based on a
set of mapping tools developed at Utah State University and has the ability to support and
display a variety of spatial data types, including terrain; point, line, and polygon features; as well
as imagery. The WIS is also customizable to any watershed with readily available sources of data
