IPSFC Annual Report 1953
INTERNATIONAL PACIFIC SALMON FISHERIES COMMISSION APPOINTED UNDER A CONVENTION BETWEEN CANADA AND THE UNITED STATES FOR THE PROTECTION, PRESERVATION AND EXTENSION OF THE SOCKEYE SALMON FISHERIES IN THE FRASER RIVER SYSTEM ANNUAL REPORT 1953 COMMISSIONERS ROBERT J. SCHOETTLER SENATOR THOMAS REID A. J. WHITMORE ALBERT M. DAY ELTON B. JONES H. R. MacMILLAN OFFICERS LOYD A. ROYAL ROY I. JACKSON Director Assistant Director NEW WESTMINSTER CANADA 1954 FIGURE 1.-Sockeye spawning scene on the Upper Horsefly River in August 1953, showing the remarkable "Rebirth" of the Quesnel sockeye run. REPORT OF THE INTERNATIONAL PACIFIC SALMON FISHERIES COMMISSION FOR THE YEAR 1953 In the year 1937 the President of the United States of America and the Government of the Dominion of Canada, recognized that the protection, preservation and extension of the soclieye salmon fisheries in the Fraser River system were of common concern to the United States of America and the Dominion of Canada: that the supply of this fish in recent years had been greatly depleted and that it was of importance to the interests of both countries that this source of wealth be restored and 1tiaintained. A Conv'.ention to the above effect was ratified on July 28, 1937, including therein specific terms of reference for accomplishing the protection, preservation and extension of the sockeye salmon fisheries in the Fraser River system and an equal sharing of the allowable harvest of the resource. The Commission, appointed under the Convention, has now functioned for the initial treaty period of sixteen years with the members appointed originally by Canada and the United States and with individual replacement members appointed later by each country as vacancies occurred. -

Tailings Dam Spills at Mount Polley & Mariana Summary
BY JUDITH MARSHALL August 2018 Tailings dam spills at Download the Mount Polley & Mariana full report at: corporatemapping.ca/ CHRONICLES OF DISASTERS FORETOLD tailings-disasters Summary THIS PAPER EXPLORES THE MANY PARALLELS between the tailings dam spills at the Mount Polley mine in British Columbia (BC), Canada, and the Samarco mine in Mariana, Minas Gerais, Brazil. The Mount Polley disaster took place in August 2014, when the dam holding toxic waste from the copper and gold mine collapsed, creating the largest environ- mental disaster in Canada’s mining history. It was not long after — in November of the following year — that the largest mine disaster in Latin American history took place in Mariana, Brazil, when an even larger reservoir of waste collapsed at the Samarco iron mine.

BY JESSE ALLEN, USING LANDSAT DATA FROM THE U.S. GEOLOGICAL SURVEY. — VISIBLE EARTH, NASA The enormity of tailings ponds Despite their name, tailings ponds are often more like lakes — many square kilometres in size, held in by dams that may be from 40 to more than 100 metres high. “Tailings” refers to the chemical-laden waste rock left behind from the processing of ore: in milling and separating ore from marketable minerals, a huge quantity of waste rock is ground to the consistency of sand and ends up mixed with a tremendous amount of water into a “slurry,” which is then piped into a tailings pond. The solids settle to the bottom of the pond and also form “tail- ings beaches” that become an important buffer between a pond’s embankment (waste rock set 2 SUMMARY — TAILINGS DAM SPILLS AT MOUNT POLLEY AND MARIANA up to hold in solids) and the water. -
Eocene Paleo-Physiography and Drainage Directions, Southern Interior Plateau, British Columbia1
215 Eocene paleo-physiography and drainage directions, southern Interior Plateau, British Columbia1 Selina Tribe Abstract: A map of reconstructed Eocene physiography and drainage directions is presented for the southern Interior Plateau region, British Columbia south of 53°N. Eocene landforms are inferred from the distribution and depositional paleoenvironment of Eocene rocks and from crosscutting relationships between regional-scale geomorphology and bedrock geology of known age. Eocene drainage directions are inferred from physiography, relief, and base level elevations of the sub-Eocene unconformity and the documented distribution, provenance, and paleocurrents of early Cenozoic fluvial sediments. The Eocene landscape of the southern Interior Plateau resembled its modern counterpart, with highlands, plains, and deeply incised drainages, except regional drainage was to the north. An anabranching valley system trending west and northwest from Quesnel and Shuswap Highlands, across the Cariboo Plateau to the Fraser River valley, contained north-flowing streams from Eocene to early Quaternary time. Other valleys dating back at least to Middle Eocene time include the North Thompson valley south of Clearwater, Thompson valley from Kamloops to Spences Bridge, the valley containing Nicola Lake, Bridge River valley, and Okanagan Lake valley. During the early Cenozoic, highlands existed where the Coast Mountains are today. Southward drainage along the modern Fraser, Chilcotin, and Thompson River valleys was established after the Late Miocene. Résumé : Cet article présente une carte reconstituée de la géographie physique et des directions de drainage, à l’Éocène, pour la région du plateau intérieur de la Colombie-Britannique, au sud du 53e parallèle Nord. Les formes de terrain à l’Éocène sont déduites de la distribution et du paléoenvironnement de déposition des roches de l’Éocène et à partir de relations de recoupement entre la géomorphologie à l’échelle régionale et la géologie du socle, d’âge connu. -

Environmental costs of salmon culture and other food systems in the Northeast Pacific 167 the assimilative capacity of an ecosystem and this information is necessary to manage the overall scale of aquaculture. At present, far-field effects have not been observed at the relatively low density of netpen operations in the Pacific Northeast. They are therefore a Category IV hazard and a quantitative environmental cost assessment is not possible at this time. PUTTING THE ENVIRONMENTAL COSTS OF SALMON PRODUCTION IN PERSPECTIVE WITH THE COSTS ASSOCIATED WITH OTHER FORMS OF FOOD PRODUCTION Assessing the environmental costs of other food producing activities is being undertaken by other contributors in these proceedings. However, the following comments are provided in an attempt to put the costs of salmon aquaculture into perspective with the environmental costs of producing an equivalent amount of beef. Beef cattle production Image 1 is a photograph of an old growth forest IMAGE 1 in the Canadian Rockies. These forests and Old growth forest on Horsefly Lake in the Canadian their associated wetlands support small, but Rockies diverse, communities of plants and animals. The organic debris created by wind-thrown old- growth cedar, Douglas fir, true firs, hemlocks and birch trees creates a dense detrital food web that support marvelous communities of fungi, ferns, mosses and lichens. Many of the Douglas fir trees are five and six feet in diameter. They do not have a limb on them for perhaps the first hundred feet of their 200 foot heights and they are (by actual tree-ring counts) several hundred years old. -
