ENVIRONMENTAL INVENTORY OF LOWER ST. LOUIS RIVER COVERING PROPOSED IMPROVEMENTS TO DULUTH-SUPERIOR HARBOR, MINNESOTA AND WISCONSIN FINAL REPORT

Abstract

This report is the result of studies conducted in St. Louis River-Duluth Harbor in the summer of 1975. Specifically, three aspects of the harbor's biota were included, and are treated in subsequent sections. These include a sur­vey of aquatic vascular plants, fish populations and benthic organisms in the harbor. The proposed dredged spoil disposal sites (areas 1-5 in figure 1) received the most attention. An introductory section provides a general over­ view of the harbor.
