The purpose of this study was to conduct a survey of the pore water chemistry of a few lakes with dissimilar trophic conditions and geothermal characteristics within the Taupo Volcanic Zone. Three lakes (Ngahewa, Okaro and Taupo) were studied in greater detail while five others (Ngapouri, Okareka, Rotokawau, Rotorua and Tikitapu) were sampled infrequently. Major emphasis was placed on pore water dissolved gases, but additional samples were also analyzed for a variety of solid phase components and interstitial chemical constituents such as nutrients and organic acids (and major ions for a few samples). This report provides a summary of these data along with graphical presentation. (auth.)
