However, for First Nations in British Columbia, these lands have been occupied since time immemorial and their riches cannot be counted tree- by-tree, fish-by-fish, or stone-by-stone . Instead, the wealth of these landscapes can only be known through the relationships between the people, the lands, and the waters . It is because of the knowledge of these relationships that First Nations in British Columbia assume a responsibility in deciding how the lands and resources in British Columbia are to be used . Unfortunately, capacity to participate as equal partners in decision-making is low among British Columbia’s more than 200 First Nations communities . However, lack of capacity can no longer be an excuse for governments and industry to exclude First Nations from the decision- making table . Nor can we as indigenous peoples afford to watch from the sidelines as others make decisions that will affect our communities, lands and resources both today and in the future . Perhaps nothing better illustrates this than the catastrophic failure of the tailings dam at Mount Polley . Expected to last in perpetuity, the tailings dam breach released 25 million cubic metres of mine waste into the receiving environment . The disaster not only devastated communities living downstream but also triggered anxiety in government, industry experts, shareholders and, most especially, communities living downstream of major tailings facilities across the province as everyone wondered, “Could a similar event happen again?” Following the investigation into the Mount Polley disaster by an expert panel, we now know that without significant changes to the current mining practices, in British Columbia alone we can expect two tailings dam failures every 10 years. With this latest disaster occurring on August 4, 2014, the clock continues ticking down reminding us we no longer have the luxury of time . We do, however, have an opportunity to make lasting change and ensure that no community will ever face the same devastation experienced by the communities downstream of Mount Polley . This will demand a commitment to work together with government and industry in order to change past practices that can impact, sometimes irreversibly, the homes and livelihoods of First Nations . Page 3 Executive Summary Since the failure of the Mount Polley tailings facility in August, 2014, there has been increased awareness of the long-term risks from potential failures of tailings facilities to the fish, wildlife, and general ecology of downstream rivers and lakes and the communities that depend on them . This GIS-based analysis of northern British Columbia and southeast Alaska (starting at Mount Polley and extending north to the Yukon border) shows the streams, rivers, lakes, and wetlands that would be impacted by a failure in existing tailings facilities, the special habitats for salmon and other fish and wildlife within the potentially impacted areas, and the First Nations communities and other cities and settlements that could be affected by future tailings failures . The analysis includes 35 tailings ponds at 26 mine site locations in northern British Columbia (from Mount Polley to the Yukon border) . The mines encompassed in this area are listed in Appendix I and include Red Chris, Endako, Mount Milligan, Yellowjacket, and others . A total of 8,678 kilometres of streams, rivers, and lakes lie downstream of the flow paths of contaminants that would result from failures in the 35 tailings ponds facilities within the selected area . Of this total, 3,275 kilometres are immediately downstream of these tailings facilities and 5,403 kilometres are further downstream where the contaminants could eventually reach . Within the selected area, there are 33 First Nations communities in watersheds that could be impacted by failures in the 35 tailings facilities, including 17 (52%) that would be within watersheds impacted by immediate flow paths of contaminants . Additional First Nations communities further upstream of potential contaminant flow paths may also be affected because of impacts to migrating fish that could be impacted downstream of a tailings facility failure . There are 208 additional cities and settlements within watersheds that would be impacted by downstream flow from failures of tailings facilities — 69 in watersheds that would receive immediate contaminant flows from failures in tailings facilities and 139 in watersheds that would receive eventual contaminant flows . Page 4 The amount of identified important anadromous fish habitat potentially impacted by a failure of the 35 tailings ponds is significant . The total kilometres of habitat downstream of tailings pond facilities is listed by species, along with additional habitat upstream of potential contaminant flow paths (access requiring migrating through potential flow paths) . • Chinook Salmon: 2,575 km (10,238 additional km upstream of flow paths) • Chum Salmon: 1,229 km (1,207 additional km upstream of flow paths) • Coho Salmon: 2,184 km (6,123 additional km upstream of flow paths) • Pink Salmon: 1,512 km (2,015 additional km upstream of flow paths) • Sockeye Salmon: 2,735 km (5,910 additional km upstream of flow paths) • Steelhead: 1,229 km (3,085 additional km upstream of flow paths) Because mining activities take place on Indigenous peoples’ traditional lands and disproportionately impact Indigenous communities, the principle of free, prior and informed consent must be applied in advance of mining operations, from exploration through all phases of development, including post-closure . Project planning must engage and be led by the communities which are most connected with these landscapes . A high priority should be placed on protecting entire river, lake, and wetland ecosystems from industrial activities and impacts . A renewed focus on establishing headwater to mouth watershed protected areas for river systems with full complements of migratory fish is needed to compensate for freshwater habitat and biodiversity lost and impaired in other watersheds . Protected areas should encompass watersheds and waterways to ensure that rivers remain unfragmented and hydrological flows remain unimpaired . Mining companies and government entities should ensure that communities impacted by mining activity secure lasting, long-term economic benefits that enhance community health and sustainability . Communities and the public should be protected by funding mechanisms against unanticipated post mine-closure impacts or financial burdens for clean-up and remediation . Page 5 Introduction Northern British Columbia is one of the most visually stunning and ecologically vibrant regions in North America . From dramatic snow-capped mountains to lush river valleys and majestic lakes, this still largely pristine region harbors a rich variety of wildlife that has sustained indigenous peoples for thousands of years . Rivers such as the Stikine, Nass, and Skeena — the origins of which form what is often called the Sacred Headwaters — as well as many others provide large networks of salmon and steelhead spawning habitat that have not been heavily altered, blocked, or degraded by human activities .1 These migratory fish provide sustenance and income for many northern First Nations communities and provide a healthy supply of fish for the major fisheries in southeast Alaska and coastal British Columbia . These fish populations also constitute a critical food source for the grizzly bear and form an integral part of the biological food web . Anadromous fish like salmon and steelhead have been found to reallocate considerable amounts of sea-born nutrients to the inland aquatic communities upstream where they breed as well as to the terrestrial environments in those watersheds via predatory birds and mammals 2. And although the British Columbia interior has witnessed heavier industrial disturbance levels than northern regions of some provinces, the intricate networks of rivers and lakes throughout the region continue to provide critical spawning habitat for the well-known Fraser River salmon run . Northern British Columbia is also increasingly being viewed as one of North America’s next great mining boom regions . The opening of numerous large mining projects as well as the construction of the Northwest Transmission Line, which was built primarily to provide energy for large industrial projects in northwestern British Columbia,3 has led to projections of as much as a 300 percent increase in mining output in northern British

Declining metal prices resulted in the closure of the last producing mine in 1957, but in recent years extensive geophysical and geochemical surveys have been made by several major exploration com­ panies and new prospects have been discovered.

    BRITISH COLUMBIA MINISTRY OF WATER, LAND AND AIR PROTECTION - 2002 Environmental Indicator: Fish in British Columbia Primary Indicator: Conservation status of Steelhead Trout stocks rated as healthy, of conservation concern, and of extreme conservation concern. Selection of the Indicator: The conservation status of Steelhead Trout stocks is a state or condition indicator. It provides a direct measure of the condition of British Columbia’s Steelhead stocks. Steelhead Trout (Oncorhynchus mykiss) are highly valued by recreational anglers and play a locally important role in First Nations ceremonial, social and food fisheries. Because Steelhead Trout use both freshwater and marine ecosystems at different periods in their life cycle, it is difficult to separate effects of freshwater and marine habitat quality and freshwater and marine harvest mortality. Recent delcines, however, in southern stocks have been attributed to environmental change, rather than over-fishing because many of these stocks are not significantly harvested by sport or commercial fisheries. With respect to conseration risk, if a stock is over fished, it is designated as being of ‘conservation concern’. The term ‘extreme conservation concern’ is applied to stock if there is a probablity that the stock could be extirpated. Data and Sources: Table 1.

(A study supported by the Northern Fund under the auspices of the Pacific Salmon Commission) Ian Boyce, Peter Etherton, and Bill Waugh Fisheries and Oceans Canada Suite 100, 419 Range Road Whitehorse, Yukon Territory Y1A 3V1 Executive Summary A total of $64,600 was set aside from the Northern Fund to support the collection of tissue samples from Stikine, Taku and Alsek river Chinook and sockeye salmon stocks in 2012, in order to continue development of DNA baselines for genetic stock identification purposes. A total of 26 Chinook salmon samples were collected from four spawning locations, and a total of 763 sockeye salmon samples were collected from 14 spawning locations. Sample collection took place from July to October. The locations sampled were remote and generally not accessible by road except to limited departure points (Dease Lake, Telegraph Creek, Atlin, and Haines Junction). Therefore access was primarily via helicopter or float-plane. Fish capture methodology included weirs, angling, gaffing, gillnetting and seine netting for post-spawn fish. i | P a g e 1.0 INTRODUCTION 1 2.0 OBJECTIVES 1 3.0 METHODS 1 4.0 RESULTS AND DISCUSSION 3 4.1 BUDGET AND PROJECT OPERATIONS 10 5.0 CONCLUSION 10 6.0 ACKNOWLEDGEMENTS 11 7.0 LITERATURE CITED 11 List of Tables Table 1.

Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 255 p. Populations of Pacific salmon (Oncorhynchus spp.) in southeast Alaska and adjacent areas of British Columbia and the Yukon Territory show great variation in biological characteristics. An introduction presents goals and methods common to the series of reviews of regional salmon diversity presented in the five subsequent chapters. Our primary goals were to (1) describe patterns of intraspecific variation and identify specific populations that were outliers from prevailing patterns, and (2) evaluate escapement trends and identify potential risk factors confronting salmon populations. We compiled stock-specific information primarily from management research con- ducted by the Alaska Department of Fish and Game.
