The U.S. Geological Survey's Streamer application allows users to explore where their surface water comes from and where it flows to. By clicking on any major stream or river, the user can trace it upstream to its source (s) or downstream to where it joins a larger river or empties into the ocean.

The Freshwater Explorer is map-centric and mobile-friendly, and works on all different screen sizes ranging from desktop computers and tablets to mobile phones. The application can be download to a third-party PC with full access to modify with an ArcGIS account. Preferred citation: Cormier S., Wharton C., Olson J., U.S. EPA Freshwater Explorer. V:...
EPA’s Freshwater Explorer allows users to quickly access and visualize predicted background salt and mineral levels for approximately 2.65 million stream segments of a few kilometers each. Users can conduct geographical searches, access information about how maps and water quality values are estimated in Freshwater Explorer, and access datasets and...
EPA’s Freshwater Explorer is most appropriate for assessments to see how measurements in watersheds differ from predicted background conductivity (a measure of salinity) and relationships among other water quality parameters, such as nutrients and land cover. It allows users to perform their own geographical searches and visualize calculated backgr...
EPA’s Freshwater Explorer works best when launched with Google Chrome. From the opening view, scroll past the opening title until a colorful map of the United States appears. Wait for it to load.Colors—Maps in Freshwater Explorer show predicted fresher water in blue, and more mineralized water in yellow.Tabs allow you to explore pre-loaded searches or do your own deep dive. The first four tabs at the top are fixed views. It’s a good way to try the Explorer. Information about these views are in the...Data and metadata—Links are in the information at the top right “Data Access,” in pop boxes, or scroll down for the link list and disclaimer as shown here.What is Fresh Water? Fresh water is characterized by the concentration of dissolved mineral ions in the water, and is essential for drinking water, agriculture, industry, and aquatic life. Increases in minerals and ion levels sometimes indicate a source of pollution in freshwater systems. Higher levels of minerals in the water can cause harmful alg...
