Real-time data typically are recorded at 15-60 minute intervals, stored at the gaging station and then transmitted to USGS offices every few hours.

Recording and transmission times may be more frequent during critical events.

Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within 30 minutes of retrieval by the USGS office.

All real-time data are provisional and subject to revision.

The following stations have been or are about to be discontinued due to the lack of funding. If you have questions about specific stations, please contact Rob Waschbusch (608-821-3868 rjwaschb@usgs.gov).
