Abstract

The Coralville Reservoir, located on the Iowa River upstream from Iowa City, has been the subject of an intensive limnological study for the past five years. Interpretation of the physical, chemical and biological data obtained was difficult due to the large numbers of parameters measured and the frequency of sampling. The application of various statistical methods was undertaken in order to aid in analysis of the data. Preliminary correlation analyses yielded some meaningful correlations but had severe limitations. Auto-covariance and auto-correlation analysis for each parameter as well as cross-covariance and correlation tests between a number of parameters yielded useful data on the presence or absence of periodic components. Auto-covariance curves obtained from the study appear to be useful in determining optimal sampling frequency for each parameter.
