Data Methods

  1. Data Courtesy of CDEC
  2. Hourly data is retrieved from CDEC on a daily basis.
  3. Columbia Basin Research (CBR) QA/QC processes hourly data for outliers, false data (e.g., 32F measured by satellite), and data outside expected range of observation (e.g., 90F). Data loaded into CBR database.
  4. CBR calculates Daily Average values based on CBR cleaned hourly values.
  5. CBR calculates 7 Day Average of Daily Maximum (7DADM) values based on CBR cleaned hourly values.
  6. Query for daily average water temperature for selected year and query maximum hourly value per day for selected year.
  7. Examine daily average data for criterion during date periods.

Threshold Analysis Criteria

Please refer to the Sacramento River Temperature Task Group (SRTTG) annual reports for details on within water year activities.
