Data from realtime streamflow gages are relayed to the District's office through the Geostationary Operational Environmental Satellite (GOES) data-collection system. Data are transmitted from each station at intervals of either 3 or 4 hours and are loaded onto the District's computer system.
Realtime streamflow data available on the District Home Pages are PROVISIONAL data that have not been reviewed or edited. These data may be subject to significant change and are not citeable until reviewed and approved by the U.S. Geological Survey. Realtime streamflow data may be changed after review because the stage-discharge relationship may have been affected by:
Data are reviewed periodically to ensure accuracy. Each station record is considered PROVISIONAL until the data are published. The data are usually published within 6 months of the end of the water year.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences.
Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained by contacting the individual listed on the data page.
