The Delaware River supports thriving ecosystems and drinking water for 16 million people. How water is shared, and the quality of that water, has been the focus of decades of inter-state discussion, negotiation, and research. This data visualization story uses streamflow, salinity, and temperature to show how new USGS science and monitoring can inform water management in this age of cooperation.

The 2020 fire season provided stark evidence that wildfires are changing the landscape of America. But when a forest burns, the impacts on water supply and quality last long after the flames go out. Learn more about how wildfires threaten U.S. water supplies – and what we can do to adapt to the complex impacts of hotter and bigger fires.

The USGS has been measuring streamflow since 1889. Explore how USGS streamgages have been supporting our Nation's changing water-resource needs and priorities for 130 years in an interactive data visualization story.

The Satellite Collection Calendar tool allows users to find historical and projected satellite imagery dates based on the previous two months of data collection for the Sentinel-2A/2B/2C and Landsat-8/9 satellites.

Designing a survey for birds can be an overwhelming task. Our goal is to provide a set of simple questions to guide you through this process. Based on your answers, you will end up with guidance on the best approach to take with links to resources. In some cases, you may find that existing data sources, programs, or protocols can meet your needs.
