The U.S. Geological Survey’s National Water Information System (NWIS) created an interactive tool that maps water resources data at over 1.5 million sites across the country. The search tool allows the user to find sites by street address, location name, site number, state/territory, and watershed region. The sites are sorted into five main categories:
The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.
The U.S. Geological Survey conducts post-fire debris-flow hazard assessments for many major fires across the Western United States. The information from these assessments is provided in an interactive map, allowing users to view fires by location or name and access detailed maps of debris-flow probability in the area affected by each fire. Users can select fires by year back to 2013.
