9. USGS Streamgaging Network Typically the data is collected in 15-minute, 30-minute, or one hour intervals, but can be collected on any interval required. The data is transmitted thru the GOES satellite to our office on 1-hr or 4-hr intervals, depending on the baud rate of the transmitter. The data may be transmitted on a random interval once certain threshold limits are reached.
