Some locations available only from other agencies (such as USGS) may not appear in this app.\n\nWhy does Rivercast sometimes show slightly different flow data (CFS) than USGS?\nCFS is a calculated estimate derived from stage height. NOAA and USGS may sometimes use different data models, so results can vary slightly—usually within a few percent. Stage height should always be identical between NOAA and USGS, and designated flood stages are usually based on height in feet.\n\nWhy does Rivercast only show observations, but not forecasts, for my river?\nNOAA provides forecasts for many, but not all, monitored rivers. Some forecasts are seasonal or only issued during high-water events.\n\nMy river gauge was there yesterday, but it’s gone today. Why?\nRiver gauges occasionally have technical issues transmitting data or may even be washed out during flooding. Some are also seasonal. NOAA typically restores data within a few days or weeks.\n\nCan you add location XYZ to your app?\nWe wish we could! If NOAA doesn’t report data for that location, we unfortunately can’t include it. Rivercast displays all stations that NOAA provides for public use.\n\nFor more information, visit www.RivercastApp.com\n\nTerms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula\n\nDisclaimer: Rivercast is not affiliated with or endorsed by NOAA, USGS, or any other government entity.\n\nRivercast","facts":{"developer_id":494748553,"developer_url":"https://www.RivercastApp.com","first_released":"2012-11-17T04:15:32Z","support_url":"https://www.rivercastapp.com/","privacy_url":"https://www.rivercastapp.com/ios_privacy.html","website_url":"https://www.rivercastapp.com/","app_version":"6.09","release_notes":"- Performance, stability, and usability enhancements.\n- Looks great on iPhone Duo!\n\nIf you like Rivercast  and find it useful, please consider supporting us by Upgrading to Premium, or leaving us a favorable review.
