2018 Yellowknife Geoscience Forum Abstract and Summary Volume

2018 Abstract and Summary Volume Cover photograph Carcajou River, NWT; Viktor Terlaky, Senior Petroleum Geologist at the Northwest Territories Geological Survey The picture was taken following a rainstorm along Carcajou River, NWT, which resulted in a spectacular rainbow across the river valley. In the background are outcrops of the Late Devonian Imperial Formation, interpreted to be submarine turbidite deposits. The light bands are sandstone bodies intercalated with the darker shale intervals, representing periodic activity in sedimentation. Compiled by D. Irwin, S.D. Gervais, and V.

South Saskatchewan River Legal and Inter-Jurisdictional Institutional Water Map

South Saskatchewan River Legal and Inter-jurisdictional Institutional Water Map. Derived by L. Patiño and D. Gauthier, mainly from Hurlbert, Margot. 2006. Water Law in the South Saskatchewan River Basin. IACC Project working paper No. 27. March, 2007. May, 2007. Brief Explanation of the South Saskatchewan River Basin Legal and Inter- jurisdictional Institutional Water Map Charts. This document provides a brief explanation of the legal and inter-jurisdictional water institutional map charts in the South Saskatchewan River Basin (SSRB). This work has been derived from Hurlbert, Margot. 2006. Water Law in the South Saskatchewan River Basin. IACC Project working paper No. 27. The main purpose of the charts is to provide a visual representation of the relevant water legal and inter-jurisdictional institutions involved in the management, decision-making process and monitoring/enforcement of water resources (quality and quantity) in Saskatchewan and Alberta, at the federal, inter-jurisdictional, provincial and local levels. The charts do not intend to provide an extensive representation of all water legal and/or inter-jurisdictional institutions, nor a comprehensive list of roles and responsibilities. Rather to serve as visual tools that allow the observer to obtain a relatively prompt working understanding of the current water legal and inter-jurisdictional institutional structure existing in each province. Following are the main components of the charts: 1. The charts provide information regarding water quantity and water quality. To facilitate a prompt reading between water quality and water quantity the charts have been colour coded. Water quantity has been depicted in red (i.e., text, boxes, link lines and arrows), and contains only one subdivision, water allocation.
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.
Hay River Region

The Hay Water RiverMonitoring Activities in the Hay River Region Kátåo’dehé at Enterprise Kátåo’dehé is the South Slavey Dene name for the Hay River. In Chipewyan, the Hay River is Hátå’oresche. In Cree, it is Maskosï-Sïpiy. The Hay River is a culturally significant river for Northerners and an integral part of the Mackenzie River Basin. Given its importance, there are several monitoring initiatives in the region designed to better understand the river and to detect changes. The information collected through these programs can also help to address questions that people may have. While amounts vary from year to year, the volume of water in the Hay River has remained relatively stable since monitoring began in 1963. Only a slight increasing trend in winter flow was revealed. Some changes in water quality were also found, such as increasing trends in phosphorus and decreasing trends in calcium, magnesium and sulphate. This means that the levels of these substances have changed since sampling began in 1988. Further work is needed to understand the ecological significance of these trends. Overall, the water quality and quantity of the Hay River is good. Continued monitoring activities will increase our knowledge of this important river and identify change. It is important that all water partners work closely together on any monitoring initiatives. 1 Water Monitoring Activities in the Hay River Region For information regarding reproduction rights, please contact Public Works and Government Services Canada at: (613) 996-6886 or at: [email protected] www.aandc.gc.ca 1-800-567-9604 TTY only 1-866-553-0554 QS-Y389-000-EE-A1 Catalogue: R3-206/2014E ISBN: 978-1-100-233343-7 © Her Majesty the Queen in right of Canada, represented by the Minister of Aboriginal Affairs and Northern Development Canada, 2014 This Publication is also available in French under the title: La Rivière Hay : activités de surveillance de l’eau dans la région de la rivière Hay.

SLAVE MÉTIS ALLIANCE PO Box 2301 Yellowknife, NT X1A 2P7 July 4, 2019 Mackenzie Valley Review Board 200 Scotia Centre, 5102-50th Ave Yellowknife, NT X1A 2N7 To: Kate Mansfield & Catherine Fairbairn Re: Review Board Information Requests to Parties for Diavik EA1819-01 As requested for the Diavik Environmental Assessment (EA1819-01), the Mackenzie Valley Environmental Impact Review Board (Review Board) issued two information request to several parties, including the North Slave Métis Alliance. 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.
