Abstract The physical-chemical limnology of a desert lake in central Arizona was investigated from February 1971–July 1973. The reservoir was found to be a warm-monomictic, eutrophic lake which exhibited pronounced thermal stratification during the summer months. Surface water temperatures ranged from a minimum of ca. 9 C in January to a maximum near 30 C in July–August. Chemically the lake may be described as a hard water lake of moderately high alkalinity and salinity. The concentration of the principal ions was affected significantly by precipitation run-off. The primary nutrients N and P were subject to considerable seasonal variability, being influenced most by precipitation and phytoplankton abundance. Trace element concentrations were low and showed comparatively little fluctuation during the study.
