Annual means of specific conductance and salinity

Figure 7. Annual means of specific conductance (left axis) and salinity (right axis) at each station as a function of annual volume of freshwater inflow from the Sacramento–San Joaquin River Delta to the San Francisco Bay. For stations with both upper and lower sensors at the same geographical location, only data from the upper sensor is shown. Stations: 1) Benicia Bridge; 2) Carquinez Bridge; 3) Richmond Bridge; 4) Alcatraz Island; 5) San Mateo Bridge.
