Upper Cretaceous Aquifers
Composite Hydrographs


1/19/2018 9:08:27 AM

Additional Information
The mean and median composite hydrographs have different trends because the median curve is represented by one well (Site Number: 472641102105901) for the last 28 years of the curve, which is not representative of the entire principal aquifer. Thus, the mean composite hydrograph is probably more representative of the entire Principal Aquifer. This discrepancy is most likely due to the limited number of wells (15 wells) used to calculate the composite hydrographs.
