Studies were undertaken during 1984 to evaluate aquatic resources in the Telkwa Project study area in west-central British Columbia. Stream periphyton, invertebrates and fish populations were assessed in Goathorn and Tenas creeks and the lower Telkwa River....

This meteorology and hydrology baseline report summarizes results from 2006, 2007, and 2008 from the Davidson meteorology station and for 6 hydrometric stations established for the Davidson Project. It also includes available data from government operated...

This report includes an assessment of present water quality, a prediction of future water quality, recommended water uses that should be protected, and recommended monitoring to check whether those objectives are being met and to develop future objectives.

The purpose of this report is to assess the water quality and aquatic ecosystem data gathered to date and to recommend water quality objectives specific to the Toboggan Creek watershed. Designated water uses, to be protected by water quality objectives, are...

Predominantly all wastes, both tailing and blasted rock, contain pyrite and are classified acid generating. Acid generation occurs within waste rock fills around the property however not within tailing thus far due to sub- aqueous disposal of the product....

The Equity Silver Mine operated between 1980 and 1994, producing silver, gold, and copper from three open pits and a small underground operation. Mine components include a flooded tailings impoundment constructed from till and waste and quarried rock. This...

Telkwa Coal Limited (TCL) is proposing to develop the Tenas Project (the Project), a surface coal mine designed to produce approximately 15.0 million tonnes of washed metallurgical coal product at about 0.750 million saleable tonnes per year to be used in...

The Application should be read in the context that it is the basis for the first major stage of the Environmental Assessment Process as it applies to new mine developments proposed for British Columbia. The purpose of the Application is to provide an...

Samples were collected for the first time from a watercourse on the proposed project site on the north side of the Telkwa, and from sites on the Telkwa River and Goathorn Creek which were previously sampled in 1988. Samples were also collected from the...

Studies were undertaken during 1984 to evaluate aquatic resources in the Telkwa Project study area in west-central British Columbia. Stream periphyton, invertebrates, and fish populations were assessed in Goathorn and Tenas creeks and the lower Telkwa...

This report assess present water quality of the mainstem Bulkley and Morice Rivers, to predict future water quality, and to recommend water uses that should be protected, and to recommend provisional water quality objectives to protect those uses.

Site-specific water quality guidelines for the Skeena River at Usk for the purpose of national reporting (May 2005). This document is one in a series that presents ambient site-specific water quality guidelines (SSGs) for British Columbia and the Yukon....

In summary, the risk assessments identified COCs in soil that may have potential to cause adverse effects, especially to soil invertebrates and plants, although this is principally a theoretical risk owing to important habitat limitations in the most...

This report attempts to provide a preliminary review of the some of the possible impacts, monitoring, and mitigation measures for many of the pollution issues including sewage and waste disposal, mining and smelter activities, various large industrial...

The Equity Silver Mine operated between 1980 and 1994, producing silver, gold, and copper from three open pits and a small underground operation. Future liability is important at the site due to the environmental risk and high cost of treating acid rock...

Historical water quality data presented for the Skeena River watershed are divided into nine subsequent sections, corresponding to the nine major watershed reaches. Each section is divided into 6 subsections: hydrology, land use history, water withdrawals,...

A reconnaissance survey of Cerber Lake within the Bulkley River watershed. The purpose of this survey was to provide essential fish and fish habitat information required for resource planning or making management decisions for Cerber Lake.

An assessment of discharge regulation, aquatic monitoring, and aquatic impacts related to Bell and Granisle Mines.

This study focused on the diffuse sources of nutrients and the trophic status of the Upper Bulkley River. Monthly water chemistry monitoring of the Upper Bulkley and tributaries was conducted between November 1997 and March 2000, and the end of growing...

Natural Resource Stewardship Monitoring and Assessment Reports are a summary of existing resource value monitoring and assessment information for a given geographic area. Data in this report has been arranged into the following categories: fish and water,...
