  • Fish Passage Literature Review
    Memorandum Plaza 600 Building, 600 Stewart Street, Suite 1700, Seattle, Washington 98101, Telephone: 206.728.2674, Fax:206.728.2732 www.geoengineers.com To: Dale Kerner, Gene Bosley (Midas Gold) From: Jeff Barrett Date: December 20, 2017 File: 19270-003-00 Subject: Memorandum on Fish Passage Literature in Support of Midas Gold Idaho, Inc. - Stibnite Gold Project, Request for Additional Information (RFAI) 55. GeoEngineers conducted a review of available scientific literature to identify studies that support the contention that salmonid fish will be successful in passing through the bypass tunnel of the East Fork South Fork Salmon River (EFSFSR) being proposed by Midas Gold Idaho, Inc. (Midas Gold) in their Stibnite Gold Project (SGP) Plan of Restoration and Operations (PRO). We prioritized finding and reviewing studies documenting fish passage through tunnels, and found several papers with applicable examples. However, the literature on tunnels is limited, so we also reviewed studies that show fish passage through long culverts or fish ladders. In addition, a number of studies were reviewed to assess the role of artificial illumination in facilitating or inhibiting fish passage, with an emphasis on studies of salmonid fishes. The collected literature documents fish passage in a variety of long tunnels, culverts, and fishways, over a wide range of flows, and with variable levels of fish passage improvements. Expected conditions for fish passage through the proposed EFSFSR tunnel fall well within the range of conditions noted in the reviewed studies. We believe this literature review therefore provides a strong basis for concluding fish passage through the tunnel will be successful if appropriate fish passage structures are included in the tunnel design.

  • Studies on the Freshwater and Anadromous Fishes of the Yukon River Within Canada
    I." Environment Canada Environnement Canada Fisheries Service des peches and Marine Service et des sciences de la mer Studies on the freshwater and anadromous fishes of the Yukon River within Canada C.E. Walker PAC T/76-7 North B.C. & Yukon Br Pacific Region STUDIES ON THE FRESHWATER AND ANADROMOUS FISHES OF THE YUKON RIVER WITHIN CANADA By: C.E. Walker PAC T/76-7 Department of the Environment Fisheries and Harine Service 1090 \vest Pender Street Vancouver, B. C. V6E 2P1 July, 1976 i ABSTRACT Characteristics of the adult chinook and chum salmon populations of the Yukon River within Canada are described. Significant differences were found between the composition of the catch and the composition of the escapement in terms of sex and length. It is hypothesized that any change in the fishery from wheels to gillnet will result in greater catch of larger size fish and also of females. Such a change may have severe con­ sequences on the reproductive capacity of the populations. Ten fish populations, other than adult salmon, are described for an area from Tatchun Creek to Fort Selkirk. Salmon is the most abundant fish, with longnose sucker, Arctic grayling and slimy sculpin occurring in this order. Growth data are presented for some species. In general, the growth of fish in the Yukon River is slower than that in tributary st~eams and other waterways of the territory. The predictive value of pre-determining the location of salmon spawning habitat based on pinpointing areas that are ice-free and/or have ground water intrusion was nil.

F. Brown Fisheries and Marine Services M.S. Elson N orthern Natural Resource Services L. W. Steigenberger PAC/T-76- 4 Northern Operations Branch Pacific Reg ion Te chnica l report series PAC/T 76-4 ~ -1 i FOREWORD The north is presently involved in a period of rapid change. Modern transportation methods now permit exploration and development even in the most remote areas. In order to ensure the perpetuation of fishery resources it is essen­ tial that the resource manager attempt to minimize and control the inevitable environmental damage that results from industrial development. Recommendations on environmental protection and resource harvest must be based on biologically sound facts. This report is an information source concerning fish species and their habitat in the upper Yukon River drainage and as such is a tool for resource management. It is one of a series covering the major drainage basins in the Northern British Columbia and Yukon Division that has been assembled for the use of those people involved in fishery management and environmental protec­ tion. The report should be considered as a preliminary documentation of fisheries and related information, and as a basis from which future resource management policy may stem. The aim of habitat protection is to. balance environmental concerns with economic demands. We believe that total environmental destruction does not necessarily accompany industrial progress, and that the concept of multiple use of resources can be safely implemented.

  • The Distribution of Introduced Rainbow Trout (Oncorhynchus Mykiss) in the Upper Yukon River Basin 2013
    The distribution of introduced Rainbow Trout (Oncorhynchus mykiss) in the Upper Yukon River Basin 2013 Prepared for: Yukon Fish and Game Association Prepared by: Al von Finster, AvF R&D Funded by: Yukon Fish and Wildlife Enhancement Trust Cover Image courtesy of the 2013 Whitehorse Rapids Fishway Staff Abstract Aquatic Invasive Species (AIS) are of increasing national and international concern. Rainbow Trout are considered to be an Invasive Species in many countries. It is not native to the Upper Yukon River Basin. In 2013 we conducted a literature review of the introduction of Rainbow Trout to the Upper Yukon River Basin and a field program to determine the species introduction and present distribution. We found the pathway of introduction was a successful introduction to Jackson Lake in the 1950’s. By the 1960s the species had colonized downstream as far as McIntyre Creek. In the 1970s it was reported from the Yukon River. In the 1990s it was documented in Croucher Creek, a tributary of the Yukon River downstream of McIntyre Creek, and a single Rainbow Trout was angled from the mouth of Laurier Creek, tributary to Lake Laberge. In the 2000s Rainbow Trout were commonly seen in the Whitehorse Rapids Fishway. The field investigation included monthly sampling in the Yukon River from the Takhini River to the Lewes River dam at the outlet of Marsh Lake. The inlet, outlet and tributaries of Lake Laberge, and the Ibex River above and below the mouth of Jackson Creek were sampled on two occasions. Sampling effort included a total of 248 minnow trap/nights.
