Real-Time Data from Continuous Monitoring Stations

Data associated with monitoring stations collecting data daily, at regular intervals.

• Stations and Data
  Information from stations continuously monitoring water quality, by river basin
• Water-Parameter Averages (Data by day by parameter)
  Hourly averages are calculated from data collected every 15 minutes.
• Data for Specific Monitoring Stations
  • Daily: Hourly averages of all water-quality parameters by station.
  • Monthly: A summary of hourly averages by parameter.
  • Yearly: A summary of hourly averages by parameter.
• Site Information (table)
  See site photos, maps, parameters monitored, current measurements, latitude and longitude, and elevation. The user may sort by Continuous Ambient Monitoring Station (CAMS) number, city, river basin, elevation, or responsible entity.
