Average monthly minimum and maximum temperatures were obtained from the Victor
weather station for the period of record between 1966 and 1976. As shown, the highest
average temperatures occur during the months of July and August (71.4-69.1 °F) and
the lowest average temperatures during December and January (33.7-34.5°F).
Climate data were compiled from the two weather. stations (Victor and Bateman/Rigi)
and additional sources, as reported in Cresson Project Hydrogeochemical Evaluation,
(Adrian Brown, 2008). The precipitation record has recently been updated by Smith
Williams Consultants (SWC) and is presented in Table 2.2, with statistics compiled in
Table 2.3 (SWC, 2008).
