|River & Flood Levels
|A great river adventure requires good planning. Thunderstorms are frequent and sudden in the summer months and a downpour can ruin an otherwise enjoyable outing.
Flash floods are a risk at all times of the year. While in the area, listen to local radio stations for the latest weather. In general, the National Park Service will close the river to non-motorized vessels when the river level reaches two feet above normal. Those "flood levels" are indicated at the right. For the most up-to-date information about river closures, please visit our Facebook page. (A link is provided on the Park Home page.)
In flood conditions, the river runs faster, carries debris and is very treacherous. On land, flooding can make road crossings dangerous as well, never drive across a flooded roadway! Most flooding deaths occur in cars that are swept away.
Remember, you are responsible for your own safety. Proper planning and alertness to your surroundings should keep the weather where it belongs - as a topic of conversation, not a cause of harm.

Reading the Gages
The links on the above right lead to automated river level stations in several areas of the park. They will usually show two graphs:
Gage Height: Water level at the river gage. Compare the "flood" level cited to the right with the river level on the graphs (click river area of interest) to find if the river is up. If the river is at flood level, it is likely to be closed to non-motorized vessels. If it is at "Flood Level" or is rising toward it, dangerous conditions either exist or are likely.
Discharge: This is the volume of water moving past a certain point. In general, the larger the volume, the faster water is moving downstream.
Remember to pack dry clothes in a watertight container such as a trash bag! In cooler weather, you might want supplies to start a fire as well.
