Environmental Monitoring Program (Field)

The Environmental Monitoring Program (Field) section monitors discrete and real-time water quality throughout the Sacramento-San Joaquin Delta and San Pablo Bay. Discrete data is stored online here: http://www.water.ca.gov/bdma/meta/.

Data is transmitted to the California Data Exchange Center (CDEC) via wireless telemetry real-time to provide information on Delta conditions. Click here for station map and click on each station code for the station Meta Data lookup (D6A, in Suisun Bay; D12A, D16A, P8A, C7A, C10A on the San Joaquin River;C3A, D10A, D24A, D11A on the Sacramento River, D29, D19A, D7A, D8A, D9A in the Delta). For more station Meta Data details, you can also visit the link " Description of Both Active and Historic RTM Sites " in the Real Time Monitoring Website: http://www.water.ca.gov/rtm/meta/.  When you click on the link, you can see the two existing descriptions of both current and historic stations .

We also provide instrumentation support for special studies used by scientist to find answers to the complex ecological issues that face the Delta. These systems utilize a standalone instrument (YSI Model 6600 and the new EXOs) that is dropped into the water and floated at one meter depth. At critical locations redundant Instruments are installed to insure the constant availability of data. The Section is always ready to install at new locations as the needs of the Department change.
