USGS National Water Information System Mapper

The USGS has created an online mapping tool to easily access water resource data across the United States.  The National Water Information System Mapper offers up to date information on groundwater, surface water, springs, atmosphere data, and more.  The tool comes with a search feature to look up specific addresses or locations along with an export tool to convert the data into a Excel or ArcGIS compatible format.  Additionally, there are GIS layers you can overlay on the map such as watershed boundaries and aquifers.  Curious how clean the water in your town is?  Then check out the map by clicking the image below!
