We have numerous creeks, streams and rivers across our viewing area. Not all are going to have river monitoring gauges but many do. Here’s some helpful information for you to check whether you plan to be on the water, camp near the water, or if you live near a creek or river. A few things about river and stream monitoring:

Not all rivers or creeks will have forecasts. Some are observation data only
River forecasts are updated several times a day based on need during heavy rain events
Click on the stream/river name to see a graph. Then click on the graph image for even more information.
When you click the link below, the map will show a diamond or a round circle where gauges are
The diamond represents a gauge that has observation information only. Past to current stage
The circle represents a river gauge that includes observation data and a forecast

MODERATE FLOODING (RED): Inundation of structures and roads near streams. Some evacuations of people and/or transfer of property may be necessary.
