Book excerpt: The St Marys River, the connecting channel between Lake Superior and Lakes Huron and Michigan, is part of the vast surface waters of the Great Lakes and therefore bears a considerable amount of recreational boat and commercial ship traffic. Several questions have been raised regarding the impact of large ship passage on the indigenous fish and wildlife. Extended winter operation of the lock complex at Sault Ste. Marie, Michigan has been proposed to 31 January + or - 2 wk. This contract was prepared to obtain data to allow predictions regarding the impact of winter shipping to as late as 15 February on the St. Marys River. Because of the surge and currents that ships can generate, they may have substantial effects on the spawning grounds of such important fish as lake whitefish (Coregonus clupeaformis), lake herring (C. artedii), and other recreationally important species. There is also concern about the effects of ship passage on benthic invertebrate communities, and how sediment resuspension, possibly caused by ship traffic, may impact the primary producers in the system, especially the aquatic macrophytes. The fauna of the St. Marys River is a combination of animals drifting or moving in from Lakes Superior, Huron, and Michigan and those produced within the system. The river includes backwater; connecting channels, embayments, and Lakes; scattered wetlands; and other estuarine habitat. To examine some of the impacts of winter and summer navigation on the indigenous fauna and flora, we studied three components of the St. Marys River ecosystem; the macrophyte community, the drifting benthos and zooplankton community, and the larval fish community.

Liston and published by . This book was released on 1986 with total page 828 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to expand existing biological and physical/chemical data for the St. Marys River during 1982 and 1983 to help assess environmental impacts from proposed navigation season extension (January 31 2 weeks). This study builds upon previous data bases gathered during 1979 - 1981. Previous investigations were limited mainly to localities near Neebish Island, while the present study involves sampling sites ranging over some 64 km (40 mi) of the St. Marys River, including a site above the locks at Sault Ste. Marie. Similar techniques have been employed over the years whenever possible to assure comparability for assessing potential natural annual changes in the system's biota nd limnological characteristics. Thus, extensive pre - project data, involving collections carried out during 1979 through 1983, are available. This report contains data on the following topics: Physical and chemical aspects of water; winter sedimentation rates; benthic macroinvertebrates; aquatic macrophytes and primary productivity; ichthyoplankton; and, juvenile and adult fish. Keywords: St. Marys River system; Study stations; Aquatic plants; Primary production; Winter sedimentation; Benthic macroinvertebrates; Fish. (kt).
