Rivercast Avis

Rivercast™ puts the river level data you need at your fingertips with its intuitive and interactive maps and graphs.

• Search interface to find river gauges by waterway name, state, or NOAA 5 digit station ID.

• This app uses NOAA and AHPS (Advanced Hydrologic Prediction Service) for its raw data for our custom graphing and mapping solutions.

Rivercast™ uses the latest observation and forecast data available, and requires an Internet connection for use.

NOAA and USGS estimates may sometimes slightly vary due to using different data models.

Rivercast's map not only shows you where the stations are, but color codes them when it can to give you an indication whether the location is at normal levels, approaching flood levels, or above flood stage.

Favorites, Map "Instant Observations", and Hydrograph data is viewable in feet or cfs (when available).

To customize your graphs for what's important to you, you can add your own level lines to mark things like sandbars, rocks, bridges, safe conditions, or whatever you would like.

Stage height should always be identical between USGS and NOAA.

• Customize your graphs by adding river levels that are relevant to you.

All observation and forecast data is in your local time (per your device) for your convenience.

Designated flood stages are based on stage height in feet in the USA.

• NOAA issues forecasts for many, but not all, rivers it monitors.

They occasionally have technical problems transmitting their data, or can even get washed out during extreme flooding.
