We've updated the Map Viewer! It has a cleaner interface and more functionality. You can draw and annotate your map, export shapefiles, do limited analysis, and share your map for later use or collaboration.
Map Viewer is a free, web-based GIS application that provides water feature information in the form of an interactive map of Colorado. Features can be selected and identified, and links are provided to more detailed information and data available for download for that feature.
There are a variety of map viewers designed with specific tasks in mind. To see a list, check out DWR's FAQ here
