Groundwater flow in the Precambrian Shield is considered to be negligible. Winter base­ flow records, chemical analyses of river waters, the presence of springs, and the local occurrence of halophytic flora provide evidences of groundwater movement in regions where no piezometric data from borings are available. Quantitative information on the groundwater contribution to the Upper Liard basin is obtained from the relation between discharge and specific conductance. This relation

  • Proposed Tłı̨chǫ All-Season Road Executive Summary March 2016
    Proposed Tłı̨chǫ All-season Road Executive Summary March 2016 Proposed Tłı̨ chǫ All-season Road Project Description Report March 2016 Department of Transportation i Proposed Tłı̨chǫ All-season Road Executive Summary March 2016 EXECUTIVE SUMMARY This project description report (PDR) has been written to accompany the Type A Land Use Permit and Type B Water Licence applications to the Wekʼèezhìı Land and Water Board (WLWB) for development of the proposed T ł ı̨ c h ǫ All-season Road (TASR). These applications are being submitted by the Department of Transportation of the Government of the Northwest Territories (DOT – GNWT). The T ł ı̨ c h ǫ Government supports these applications. This project has been identified as a GNWT commitment under the Proposed Mandate of the Government of the Northwest Territories 2016-2019 (GNWT 2016). Over the years, DOT and T ł ı̨ c h ǫ Government have contemplated the possibility of improved transportation to the Wekʼèezhìı area. In 2011, both governments became reengaged under the T ł ı̨ c h ǫ Roads Steering Committee (TRSC) in order to assess the feasibility, desirability and implications of realigning the T ł ı̨ c h ǫ Winter Road System to provide improved community access. As of May 2013, the vision of the TRSC has been to pursue development of an all-season road. The route would end at the boundary of the community government of Whatì and predominantly follow ‘Old Airport Road,’ an existing overland alignment that was utilized up until the late 1980s as an overland winter road. The proposed TASR is defined as an all-season road approximately 94 km in length and 60 m in width with a cleared driving surface of approximately 8.5 m in width in order to accommodate a two lane gravel road with culverts and/or double lane bridges over water crossings as necessary.

  • Represent 25 Species
    59.9(71.2) Article II.- MAMMALS FROM THE ATHABASKA-MIACKENZIE REGION OF CANADA. By J. A. ALLEN. During the summer of 1907 Mr. E. Thompson Seton, accompanied by Mr. Edward A. Preble of the Biological Survey as assistant, made an expedi- tion to the Barren Grounds in the vicinity of Aylmer Lake, Mackenzie District, for the purpose of natural history exploration. Their route was by way of the Athabaska River, Slave River, Great Slave Lake, and the chain of lakes northeastward to Aylmer Lake. The birds and mammals obtained on this trip were purchased for this Museum, through the generosity of Mrs. Morris K. Jesup. The birds have already been briefly reported upon by Mr. Seton; ' for the sake of the localities, and the measurements taken by Mr. Preble from the specimens in the flesh, it seems worth while to record these data for the mammals, which comprise about 2-70 specimens, and represent 25 species. The principal points at which collections were made are: Athabaska River, 20 miles below Athabaska Landing, May 18 and 19; Grand Rapids, Athabaska River, May 22-24; Fort McMurray, Athabaska River, May 28, 29; Slave River, June 6-8; Fort Smith, Slave River, on the Athabaska- Mackenzie boundary, June 13-July 2; Great Slave Lake (various points), July 19-27, September 10-27; east shore of Artillery Lake, August 2-5; Aylmner Lake (various points), August 14-29; Artillery Lake (mostly east shore at tree limit), August 31-September 8. The collection consists mainly of rodents, but lacks representatives of the genera Phenacomys and Synaptomys; it also contains only a single specimen of Sorex, and single specimens each of three species of Putorius; also only two specimens of Lepus, and one of Eutamias.

  • Movements and Distribution of the Bathurst and Ahiak Barren-Ground
    Movements and distribution of the Bathurst and Ahiak barren-ground caribou herds 2005 Annual Report Submitted to West Kitikmeot Slave Study Society Submitted By Project Leader Anne Gunn Project Team Adrian D’Hont, Judy Williams Organisation Wildlife Division, Environment and Natural Resources, Government of the Northwest Territories, Yellowknife. 2 Summary: Objectives for 2005 included deploying 10 collars on cows from the Bathurst caribou herd and 10 collars on cows from the Ahiak caribou herd. A reconnaissance survey over the winter range of the Bathurst herd found heavy concentrations of caribou at Lac Grandin southeast to Rae Lakes and then low densities of caribou until east of Yellowknife. Of the 10 collars put on the Bathurst range, three died between April and June and the remaining seven calved on the Bathurst calving ground. Flights over the Ahiak winter range resulted in no caribou seen east of Contwoyto, low concentrations on the Back River and high concentrations east of Artillery Lake and in the Nonacho Lake area. Five collars were deployed east of Artillery Lake and five in the Nonacho Lake area. Of the five collars deployed in the Nonacho Lake area, two caribou migrated to the Bathurst calving ground. The remaining eight collars calved on the Ahiak calving ground. In 2005, in addition to addressing the objectives of the movement and distribution study for individual herds we successfully collared 12 cows from the Bathurst herd and 8 from the Ahiak herd. We also documented overlap in the winter distribution of Ahiak and Bathurst caribou at Nonacho Lake. Acknowledgements: West Kitikmeot Slave Study Society funded the study and we thank the Board for their continued support.

This letter specifically addresses Information Request 1: Potential impacts to cultural use of Lac de Gras Area 1. Please describe how your group used the Lac de Gras area culturally (including the hunting, fishing, trapping, gathering, and travel) before mining started there. As this question pertains to the land use prior to the development of Diavik Diamond Mine, this information was collected and provided to the regulators during the initial environmental assessment of the mine. Please see the attached “Appendix A: Can’t Live Without Work” by North Slave Metis Alliance (1999). 2. Please describe how your group would use and feel about the Lac de Gras area under the following scenarios: a) reconnecting empty pits and underground mine workings with Lac de Gras at closure (that is, Diavik’s current closure plan for the mine), b) putting processed kimberlite into the pits and underground mine workings before reconnecting them to Lac de Gras (that is, the proposed activities for this environmental assessment), c) putting processed kimberlite into the pits and underground mine workings and not reconnecting them with Lac de Gras. During a community meeting, NSMA members expressed that their interest was to have the Diavik mine site (not just the pits) return to pre-development condition as much as practicable, in such a way that the area would be the cleanest and safest environment possible for humans and wildlife.

Chouinard D. Milburn Published under the authority of the Honourable Ronald A. Irwin, P.C., M.P., Minister of Indian Affairs and Northern Development Ottawa, 1995 QS-8507-030-EF-Al Catalogue No. R72-244/1-1995E ISBN 0-662-23939-3 © Minister of Public Works and Government Services Canada FOREWORD The Arctic Environmental Strategy (AES), announced in April 1991, is a six-year $100 million Green Plan initiative. The overall goal ofthe AES is to preserve and enhance the integrity, health, biodiversity and productivity ofour Arctic ecosystems for the benefit ofpresent and future generations. Four specific programs address some ofthe key environmental challenges: they are waste cleanup, contaminants, water management, and environment and economy integration. The programs are managed by the Northern Affairs Program ofthe Department of Indian Affairs and Northern Development (DIAND); however, there is a strong emphasis on partnerships with northern stakeholders including Native organizations, other federal departments and the territorial governments. The AES Action on Water Program specifically strives to enhance the protection ofnorthern freshwaters through improved knowledge and decision-making. Water Resources managers in the Yukon and the Northwest Territories administer this Program which focuses on freshwater aquatic ecosystems. This report is the first detailed compilation ofstudies.conducted under the AES Action on Water Program. It covers work done from 1991 to 1994. Many studies have been concluded, while others are ongoing. Although data may not be available for all studies, or results are preliminary at this time, this report presents detailed background, objectives and methodology.
