Clear River Data at Your Fingertips

Rivercast’s map not only shows where gauges are located, but color-codes them to indicate whether each station is at normal levels, approaching flood stage, or above flood stage.

Tap any location to view the latest observations or open an interactive graph for detailed trends. Pinch or drag to zoom and pan, or tap and hold for precise readings using the crosshair tool.

Customize your hydrographs with personal level markers for bridges, sandbars, rocks, or safe navigation levels. Add favorite gauges for quick monitoring anytime.

Rivercast uses official NOAA observation and forecast data and requires an internet connection for data access. Data is displayed in feet or cubic feet per second (CFS) when available, always shown in your local time.

A trusted tool for boaters, fishermen, property owners, paddlers, scientists, and marine professionals who need clear, reliable river information.

River gauges are currently U.S. only.

We take our accuracy seriously!

Some Frequently Asked Questions

Where does Rivercast™ get its data?

This app uses NOAA and AHPS (Advanced Hydrologic Prediction Service) for its raw data for our custom graphing and mapping solutions. There are a few locations that are available via other government agencies (including USGS) that are not available via this app.

Why does Rivercast™ sometimes show slightly different flow data (CFS) than USGS?

CFS is a calculated estimate derived from stage height. NOAA and USGS estimates may sometimes slightly vary due to using different data models. Variances are usually within a few percent, but can sometimes be larger. Stage height should always be identical between USGS and NOAA. Designated flood stages are based on stage height in feet in the USA.

Why does Rivercast™ show only observations, but not forecasts, for my river?

NOAA issues forecasts for many, but not all, rivers it monitors. Sometimes forecasts are only issued seasonally, or during times of flooding or high water.

My river gauge was there yesterday, but it's gone today! What gives?

River gauges have a hard life. They occasionally have technical problems transmitting their data, or can even get washed out during extreme flooding. NOAA is usually pretty good about fixing them in a few days.

Can you add location xyz to your app?

We wish we could! If NOAA is not reporting it, we unfortunately are not able to add it. We include all stations that NOAA provides for public use.

I can find my location online, why can't I find it in the app?

There are some gauge locations ran by USGS or other govenment agencies that you may be able to find online or other apps that are not available via Rivercast. NOAA and other government agencies have not yet made all the raw data (required for our custom graphing and mapping solutions) available for all locations. We will add additional gauges if the data becomes available.

Is it spelled river gauge or river gage?

Both spellings are in use and considered "correct" The US Geological Survery has standardized on "gage", but most other organizations (including NOAA) have standardized on "gauge". And in case anyone was wondering, "guage" is not a word.
