FlowFinder helps you find local stream reaches, water bodies, and USGS stations. The app defaults to your current location, but allows for searches anywhere in the U.S. (using the OpenStreetMap geocoder).
FlowFinder let's you view five day forecasts for all of the ~2.7 million river reaches in the contiguous U.S. from the medium range NOAA National Water Model.
FlowFinder allows all data, maps and plots to be downloaded as csv, rda, shapefile, html, or png where appropriate.

"The National Water Model (NWM) is a hydrologic model that simulates observed and forecast stream flow over the entire continental United States (CONUS). The NWM simulates the water cycle with mathematical representations of the different processes and how they fit together." Learn More.
