San Joaquin River Water Quality Data Atlas

The San Joaquin River Water Quality Data Atlas (Data Atlas) was created to give stakeholders, agencies, and other interested persons a rapid and consistent method to access all available data on the San Joaquin River and DWSC flow and water quality conditions for the 20-year period of 1984 to 2003 (now extended to 2005). The Data Atlas includes flow and water quality data from the San Joaquin River Stevinson gage downstream to the DWSC. Tributary flow and water quality data are included for the Merced, Tuolumne, and Stanislaus Rivers, as well as Salt Slough and Mud Slough.

The Data Atlas uses a spreadsheet format that enables you to easily display daily flow and water quality data by simply entering the year of interest.

While the Data Atlas contains many files, at present, direct access from this site is provided to the Data Atlas report and six spreadsheets. Right-click on the links below to download the files.
