O&M Water Quality News & Updates

Datalogger Upgrade Project

DWR’s Division of Operations and Maintenance (O&M) currently maintains 16 automated water quality monitoring stations located throughout the SWP. Several of these autostations contained outdated dataloggers that did not allow for data automation, easy programming, or functional expandability.

As of November 2016, the O&M Water Quality Section replaced the last of the outdated dataloggers. All 16 autostation dataloggers now provide automatic QA/QC'd data uploads to the public via California's online environmental database, CDEC, thus allowing many state water contractors, stakeholders, and interested parties access to the SWP O&M Water Quality data any time.

Data Archive Project

O&M's water quality lab data from 4/3/1962 to 4/15/1998 has been added to the Water Data Library (WDL) website. This long-term data archive project involved the review of over 9,000 hard copy field data sheets and data entry and verification prior to uploading the data into the WDL in the fall of 2013. The data ranges across many constituents and locations throughout the SWP.
