  • 6 Existing Environmental Conditions in the Study Area 6.1 Study Area
    Webequie Supply Road Environmental Assessment Draft Terms of Reference 6 Existing Environmental Conditions in the Study Area 6.1 Study Area The Project is located in Northwestern Ontario, with the northern end of the road approximately 525 km northeast of Thunder Bay (refer to Figure 1.1). The Project is located on provincial Crown land, Webequie First Nation Reserve land under federal jurisdiction), and the traditional territories of Indigenous communities (refer also to Section 6.4.6 Land and Resource Use). Figure 6.1 illustrates the location of the alternative routes in relation to project area features and sensitivities. Due to confidentiality constraints (including those imposed by Webequie First Nation and Government of Ontario ministries), and the need to respect the wishes of potentially affected Indigenous communities with respect to divulging certain information on the use of lands in the project area, it is not possible to illustrate the location or bounds of a number of features and sensitivities, including First Nations’ traditional territories, individual camps/cabins, species at risk (e.g., caribou ranges), and government-regulated hunting areas (e.g., trapline licences). However, sensitive features and resources are described in general terms in this section of the ToR. The EA will summarize past investigations and analyses of alternative road alignments between Webequie and the mineral deposit area near McFaulds Lake, and will assess the potential impacts of alternative alignments in the preferred corridor for the Webequie Supply Road. The significance of an environmental impact partially depends on the geographic extent. As such, the impact assessment will be conducted on the basis of specific study areas related to the project development, adopting a multi-scale approach for describing baseline conditions (existing environment) and predicting effects from the Project.

  • Waterfowl in Iowa, Overview
    STATE OF IOWA 1977 WATERFOWL IN IOWA By JACK W MUSGROVE Director DIVISION OF MUSEUM AND ARCHIVES STATE HISTORICAL DEPARTMENT and MARY R MUSGROVE Illustrated by MAYNARD F REECE Printed for STATE CONSERVATION COMMISSION DES MOINES, IOWA Copyright 1943 Copyright 1947 Copyright 1953 Copyright 1961 Copyright 1977 Published by the STATE OF IOWA Des Moines Fifth Edition FOREWORD Since the origin of man the migratory flight of waterfowl has fired his imagination. Undoubtedly the hungry caveman, as he watched wave after wave of ducks and geese pass overhead, felt a thrill, and his dull brain questioned, “Whither and why?” The same age - old attraction each spring and fall turns thousands of faces skyward when flocks of Canada geese fly over. In historic times Iowa was the nesting ground of countless flocks of ducks, geese, and swans. Much of the marshland that was their home has been tiled and has disappeared under the corn planter. However, this state is still the summer home of many species, and restoration of various areas is annually increasing the number. Iowa is more important as a cafeteria for the ducks on their semiannual flights than as a nesting ground, and multitudes of them stop in this state to feed and grow fat on waste grain. The interest in waterfowl may be observed each spring during the blue and snow goose flight along the Missouri River, where thousands of spectators gather to watch the flight. There are many bird study clubs in the state with large memberships, as well as hundreds of unaffiliated ornithologists who spend much of their leisure time observing birds.

    Hydrogeology of Ontario Series (Report 2) AN ASSESSMENT OF THE GROUNDWATER RESOURCES OF NORTHERN ONTARIO AREAS DRAINING INTO HUDSON BAY, JAMES BAY AND UPPER OTTAWA RIVER BY S. N. SINGER AND C. K. CHENG ENVIRONMENTAL MONITORING AND REPORTING BRANCH MINISTRY OF THE ENVIRONMENT TORONTO ONTARIO 2002 KK PREFACE This report provides a regional assessment of the groundwater resources of areas draining into Hudson Bay, James Bay, and the Upper Ottawa River in northern Ontario in terms of the geologic conditions under which the groundwater flow systems operate. A hydrologic budget approach was used to assess precipitation, streamflow, baseflow, and potential and actual evapotranspiration in seven major basins in the study area on a monthly, annual and long-term basis. The report is intended to provide basic information that can be used for the wise management of the groundwater resources in the study area. Toronto, July 2002.
