Water Quality of SF Bay

Link to Water Quality of SF Bay website For over three decades the U.S. Geological Survey has maintained a program of research and observation in San Francisco Bay. The program includes regular measurements of water quality along a 145 kilometer transect spanning the length of the entire estuarine system, from the South San Francisco Bay to the Sacramento River. This website describes the measurement program, displays results of water quality measurements, and makes the full data set available to all interested users via a searchable database.

Continuous Monitoring in San Francisco Bay and Delta

Link to Continuous Monitoring in SF Bay websiteThe purpose of this project is to make time series data of salinity, temperature, water level, and SSC in San Francisco Bay available to scientists, resource managers, educators, and the general public. Data are collected every 15 minutes at many sites in the Bay and usually at two elevations in the water column at each site. Salinity, water temperature, and water level time series began in 1989 and SSC time series begin in the 1990s. All data have been reviewed, edited, and approved for release.
