Environmental Baseline Studies of St. Marys River Near Neebish Island, Michigan, Prior to Proposed Extension of Navigation Season, 1981. Great Lakes- St. Lawrence Seaway, Navigation Season Extension Program

Abstract

The objective of this study was to expand existing biological, physical and chemical data for the St. Marys River to monitor possible environmental changes associated with winter navigation-related activities, such as icebreaking and winter ship movements. The field data gathered for this study also supplements data taken during 1979 and 1980. In addition, Lake George, a non-navigated portion, was studied as a potential control site. This report contains data on the following: Benthic macroinvertebrates; aquatic macrophytes; ichthyoplankton; juvenile and adult fish; sediment chemistry of shipping vs. non-shipping channels; winter sedimentation rates; and physical and chemical aspects of the water.
