ABSTRACTData provided by the Australian Commonwealth Bureaus of Meteorology and Mineral Resources are used in this water budget study of the Queanbeyan River watershed. Air and soil temperatures show close correlation from month to month during the five‐year period. A close parallel also exists for the air temperature values and the seasonal variations in the Nett‐Moisture (rainfall minus evaporation) plots. Ground‐water levels appear to be influenced by drought periods and by under groundwater storage conditions such as “nick‐points” in the sub‐surface migration conditions. The groundwater levels were unusually high early in the drought year of 1964‐65. The annual rainfall totals for 1962, 1963, and 1966 were all exceeded by the evaporation totals. In 1964 and in 1965 (the drought year) the evaporation total exceeded the rainfall total. The minimum annual water discharge values for the Queanbeyan River ranged from 4.9″ in 196
