corresponds to a normal, etc. Once the runoff data between the two creeks were correlated,
regression equations to estimate annual runoff at Leroux Creek for the years of missing data
were developed and are shown on Figure 3 for the dry, normal and wet years.

Using the equations shown on Figure 3, Leroux Creek annual runoff was estimated using Surface
Creek data. The monthly runoff at Leroux Creek was then estimated by distributing the annual
runoff over the months of the year using the percentages shown in Table 4.

Table 5 below summarizes the actual and estimated runoff for Leroux Creek.
