- Output from four numerical-hydrodynamical models for the lake is compared to data from the field program of the Federal Water Pollution Control Agency (FWPCA) for September 1963 and/or to other limited data from which lake currents could be inferred. The comparisons between model-generated and observed currents are made by using real-time graphs for fixed locations, power spectra, lake-wide plots of average motion, progressive vector diagrams, cumulative scalar- and vector-averaged currents at fixed locations; horizontal scalar averages at various depths; and Fourier norms. The major merit of the models is their apparent ability to simulate circulation patterns. This ability can be used to expose important avenues of exchange between the northern and southern basins of the lake and to locate dominant features in the motion of the lake. The major failing of the models is their inability to simulate time-series currents at a fixed location. This failing is shown to be primarily the result of inadequate knowledge of wind and temperature fields. Choice of an appropriate means for data and model comparison evolves as a difficult and important task. Suggestions are made for model improvement and synthesis with future observations in order to focus on average motion in the deep lake.
