Correlation analysis was performed to determine the
statistical relationships of water elevations at different
stations to each other and the probability that these
relationships were due to chance. The analysis is presented in
Table 1 and indicates that a number of very high and significant
correlations exist between stations. In many instances staff
gauges have similar correlation coefficients with groundwater
monitoring wells as with other staff gauges. Thus, the
groundwater levels in most wells appear completely connected with
the stream, and stream levels determine groundwater levels.

Table 1. Pearson product moment correlation coefficients (r) for
all stations. N-2=48. Significance, *=<.05; **=<.01; ***=<.001;
ns=not significant.
