Hydrologic Monitoring
Basic hydrologic data collection, processing, analysis, dissemination, and archiving are major parts of the California Water Science Center program. Streamflow data, for example, are used for flood and water-supply forecasts, planning and design, river regulation, streamflow statistics, and research investigations. Much of the data are available on a near-real-time basis by satellite telemetry. Types of data currently collected include:
- - Streamflow data for 449 gaging stations
- - Continuous ground-water level data at more than 56 wells
- - Water-quality data for more than 52 sites
- - Stream-sediment transport data
- - Climate data
