Rivers HELP

 What Is This?
River Favorites: Provides the ability to save up to 40 favorite USGS gauges or NOAA coastal stations to a single quick-check page. The initial selection is based on popular rivers in your state. You can quickly switch to lists of river gauges in other states or search over 8,000 USGS gauges. Current flows and levels are updated automatically every 30 minutes from the U.S. Geological Survey Water Services.

Rivers are listed alphabetically based on their USGS gauge name. The tiny graphs to the left of each river name indicate the approximate rise and fall over the past seven days. Initially, a sample list of popular gauges is displayed based on your detected US state location. There are multiple options for viewing and selecting gauges. See below instructions for adding or removing gauges to your favorite list.

Color Coding of flow:
The current flow is color coded with a small arrow indicating it's change over the past four hours. This is NOT related to desireable paddling level (best determined by individual paddler judgement).
no change

Predicted Flow icon: Where is shown, clicking will display a NOAA hydrologic prediction graph for stream flow based on forcasted precipitation.

The Last USGS Refresh date and time is displayed at the top of the page. Between 8,000 and 9,000 USGS river gauges are accessed twice hourly to assure flow data is current.
