USGS real-time streamflow data are typically recorded at 15-minute intervals, stored onsite, and then transmitted to USGS offices every 1 hour, depending on the data relay technique used.
Recording and transmission times may be more frequent during critical events (floods, for example). Data from current sites are relayed to USGS offices via satellite, telephone, and/or radio telemetry and are available for viewing within minutes of arrival.
Water-quality measurements are recorded in time intervals typically as small as 5 minutes to hourly.
