A recently built simulation model for the Upper Wabash reservoir-river system in Indiana was used to study how best to operate that system. The construction of the model and of the three daily operating policies for it (that presently employed by the Corps of Engineers, the Drainage-Area Ratio and the Storage-Volume Ratio) were outlined in two preceding reports. This report discusses result that were obtained with each of the three policies applied to various reservoir configurations having up to five reservoirs, using a variety of runoff input, and for several alternative values of official flood-stage flows. The DAR and SVR policies were both superior to that used by the Corps when the runoff was less than 10 inches. Results obtained for the addition of a small water supply demand at one reservoir indicated that small changes in the mix of project require careful alteration of the operating policies throughout the system. The major conclusion was that this practical model and its operating policies can be a useful aid to design, planning and regulatory agencies. (Author)
