Abstract

Salinity, alkalinity, and dissolved and particulate organic carbon (DOC and POC respectively) concentrations in the Sacramento River water at Rio Vista were measured every three to five days during 1980 as part of an effort to identify time-dependent variations in the composition of the freshwater flow from the Sacramento-San Joaquin Delta to San Francisco Bay. Concentration ranges were generally small compared to the seasonal range of river flow rate; transport rates to the Delta and to the Bay varied primarily as a function of flow rate. Surface runoff from winter storms diluted salinity and alkalinity concentrations. DOC and POC were generally more concentrated during winter than during other times of the year. Variations in tributary flows resulted in sometimes-large salinity and alkalinity variations during spring through fall. Late summer concentrations were high because of large inflows of agricultural waste waters. POC and DOC concentrations were lowest during summer. (USGS)
