Topic	WQ: 1973-2000 pH at Five Russian River Sites

 

Caption:  This chart shows average pH for all measurements at five mainstem Russian River sites for the period 1973-2000. Note that the average pH measured at Cloverdale exceeds the Basin Plan objective for maximum pH. Average pH at Wohler Bridge increased through the 1980s but appears to have decreased since 1997. Plotted values are the average of all measurements taken in the calendar year. Number of samples per year varied from 1 to 56. Earlier years had more sampling intensity, in general. Data were provided by the North Coast Regional Water Quality Control Board (NCRWQCB). See InfoLinks for more information.
