Water temperatures of California streams, San Francisco Bay subregion

A summary of water-temperature records is presented for data collected through September 1968 in the San Francisco Bay Subregion of California. This report is one of a series covering the 11 hydrologic subregions of the State and includes data for 87 stream sites.

Water temperatures, in degrees Celsius, are summarized by months, years, and for the period of record. A description is included to identify each station where data were collected. A tolerance interval analysis indicated that 99 percent of the point water-temperature observations, determined either with thermograph probes or hand-held thermometers, should be ±0.6°C of the mean water temperature at the 95-percent confidence level. The probable total error ranges from ±0.8°C for periodic data to ±1.4°C for thermograph data.
