GVWA creates watershed products using Geographical Information Systems–GIS–that improve our understanding of the why there is so much diversity in the health of our streams. One example of this is mapping out impervious cover on a watershed wide scale to create information about which streams are most heavily impacted by stormwater run off. This example looks at headwater stream along Rt 100. To view this GIS product, scroll through the window below, or go directly to the model page.
