This is the web portal that provides access to all of the Water Atlas websites. Each Water Atlas is a website that helps communities to make informed decisions by providing up-to-date information on our vital water resources. The Atlas Program is designed to provide citizens, scientists, professionals, and planners with comprehensive and current water quality, hydrologic, and ecological data, as well as information about recreational opportunities and a library of scientific and educational materials on water resource issues. The Atlas is a "one stop information shop" for concerned citizens and scientists alike. We encourage you to use the Atlas as a tool to help in maintaining and improving our vital water resources.
