Siltation at the Continental Grain Port, Minnesota River: Diagnosis and Recommendation for Alleviation

Abstract

The Continental Grain Company operates a port on the Minnesota River near Savage for the purpose of loading grain onto barges for down~river shipment. The port consists of an inlet excavated into the south bank of the Minnesota River (Figure 1). The inlet was excavated between 1957 and 1962. Its position corresponds to the upstream limit of navigability of the Minnesota lliver. The U. S. Army Corps of Engineers dredges up to this point in order to maintain conditions for navigation. In recent years the inlet has been subject to siltation, resulting in increased requirenients for dredging in order to maintain navigability into the inlet. This report is devoted to a study of the problem and its rectification.
