A hydrograph shows how the river level changes over time at a specific location. Forecast hydrographs are displayed when flooding is expected, otherwise the hydrograph for the past few days is provided, if the data are available. At key river gages, such as along navigable rivers, daily forecast hydrographs are provided, whether or not flooding is anticipated. Click here for more information on how to read hydrographs.
