What Am I Looking At?
The National Weather Service (NWS) has a variety of flood forecast and warning tools that can provide you with critical advance notice of floods. These tools include maps and graphs that can help you know when rivers near you are going to flood, and to what extent.

Current and Forecasted River Levels:
The "hydrograph," is a chart that shows you current river levels. If a flood is predicted in your area, the hydrograph will also show you predicted flood levels and timing. It is a good idea to bookmark this page and check it regularly during times when the river level is rising or expected to flood. Hydrographs are created by the NWS.
See NWS Brochure; NWS User Guide; NWS Explanation; NWS Accuracy

Historic Crests:
Displays historic record levels of flooding for that location. Data compiled by the NWS.

Extent of Flood Waters:
Mapping from the NWS that displays the extent of flooding by "stage," or river level. First determine forecasted or historic stage of interest, then mouse over the stage to view range of possible floodwater inundation.
See NWS User Guide.

Flood Impacts by Water Level:
Specific impacts, such as street closures and other inundation impacts, as reported by emergency managers and verified by the NWS.
