The Northwest pilot has investigated a range of cumulative effect related topics as well as developed methods to assess impacts of industrial development on a selection of values at a broad spatial scale. The goal of the pilot was to improve the consistency...

As early as 1970, and continuing into the year 1973, concerned citizens of the Smithers area brought to the attention of the Water Resources Services the fact that nuisance weed growths were occurring (and increasing) in Kathlyn Lake. In response to this...

FO Habitat and Enhancement Branch initiated water quality monitoring in Toboggan Creek watershed in early 1996. Toboggan Creek is an important nursery stream for both wild and hatchery fish, primarily coho, pink, steelhead and Dolly Varden, with smaller...

The setting of water quality objectives in priority basins in British Columbia began in 1982. By the end of 2002, the Ministry of Water, Land, and Air Protection had set water quality objectives in 51 areas or basins and updated them throughout the...

The overall goal of this scan is to inform a shared vision for water monitoring and reporting in BC. This scan collected information on surface and groundwater quality and quantity monitoring and reporting in British Columbia, providing examples of who is...

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 objective of the Maxan Lake multi-land use study was to examine the interaction between various forms of land use on an area having multi-use capacity. To this end, various studies were conducted to examine different aspects of this complex subject. The...

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...

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....

This study was carried out to monitor the effects, if any, of the former Topley Concentrate Shed Site ("Topley Site") on concentrations of dissolved and total metals and other parameters and on aquatic life in the Bulkley River. The study included three...

This document contains information about Buckley lake habitat quality. Information recorded includes physical, chemical, temperature, oxygen, obstruction and pollutions, stocking, access, and habitation data. Maps and images are also included.

The Damsumlo Lake fish community was sampled with two standard experimental multi-mesh gillnets (one floating and one sinking) and five Gee-type minnow traps baited with salmon roe. Inlets and the outlet stream were sampled for fish presence by...

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...

This report presents the response to the 3rd Party Review of the Environmental Assessment for the Morrison Copper/Gold Project. The 3rd Party Review was requested by the Environmental Assessment Office and was mainly directed towards the hydrogeology, water...

This underground mining project will be located in the Bulkley-Nechako Regional District and in the traditional territory of the Wet'suwet'en people. Included in this dataset are the executive summary and elements of chapter six which deal directly with the...

This document contains a detailed fish habitat, riparian, and channel assessment of Dahlie Creek. Low channel complexity, removal of riparian vegetation, culvert obstructions to fish passage, sedimentation, altered flow regime, and channelization were some...

Approximately 800 000 m3 of acid mine drainage (AMD) is generated per year at the Equity Silver Mine southeast of Houston. This AMD would have devastating effects on the Bulkley River if it was allowed to flow untreated from the property for a prolonged...

Water quantity (streams and wells) and water quality (surface and ground) monitoring stations maintained by the Environmental Monitoring System, Northern Health Authority, BC Oil and Gas Commission, Water Survey of Canada, BC Environmental Assessment...

This report is the result of studies undertaken in 1984 that evaluated 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...

This report illustrates and discusses the temporal trends in groundwater and surface water chemistry before, during, and after mining. It is based on empirical and predicted geochemistry and on the latest groundwater modelling using the MODFLOW model.
