Weather, Water Levels and Flows, and Ice Conditions of the St. Marys River System for Extended Season Navigation
Abstract
The purpose of this study was to collect, identify, compile, and present the existing information on weather; water levels and discharge; and ice formation, coverage and thickness for the St. Marys River System connecting Lakes Superior and Huron. This includes the construction of wind roses for the winter periods (January to April) from 1969 to 1986, a river discharge chart, a water level chart and annual ice chart summaries (covering each week between 1 January and 15 February) exclusive of the years 1981 and 1982. The information thus compiled will provide a composite picture of the St. Marys River system on weather, water levels and discharge, and ice conditions for the proposed extended season operation of the Soo Locks for winter shipping to 31 January + or - 2 weeks. Keywords: Great Lakes; St. Lawrence Seaway system; St Marys River system; General study area; Major population centers; Limitations on vessel movement.
