The objective of this project is to provide estimates of inflow and outflow for any selected portion of Grand Traverse Bay. The determination is made first for the 17-year period from 1953 to 1971, for which continuous records are available on the upper Boardman River. For this period it was only necessary to find relations between the discharges of the gaged and ungaged portions of the basin. In order to extend inflow and outflow farther into the past or into the future, a deterministic hydrological model was developed for relating runoff to precipitation. This model enables the extension of the estimated inflow and outflow rates with accuracy over as many years as rainfall records are available or can be estimated.
