  • Water Quality: Second Report on Chemical Sensitivity of BC Lakes to Acidic In...

    This second summary document provides information (pH, alkalinity, calcium, and sensitivity rating) for about 760 lakes sampled between 1977 and 1986. This represents about 3.5% of the estimated 22,000 lakes in British Columbia. It provides locations where...
  • Water Quality in British Columbia Objectives Attainment

    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...
  • Water Management at Equity Silver Mines Ltd.

    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 Distribution of Aquatic Vegetation in Lakelse Lake and the Partitioning o...

    This report was requested by the regional staff as part of a complete study on Lakelse Lake. There was a need to know the value of aquatic plants, for fish habitat, and their relative value in the nutrient cycle of Lakelse Lake.
  • Seymour Lake: 1984 Data Summary and Recommendation

    The 1984 sampling program for Seymour Lake was designed to provide nutrient loading data for the lake such that a management prescription for the lake and watershed management guidelines could be proposed. Water quality sampling of the lake showed that...
  • Reconnaissance Survey of Buckley Lake

    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.
  • Literature Review and Data Summary of Studies Related to Bell Mine, Babine Lake

    This report summarizes available information on selected chemical and physical parameters of Babine Lake. The information has been reviewed in order to understand long term effects of a possible permanent copper mine tailings pond supernatant discharge into...
  • Kathlyn, Seymour, Round, and Tyhee Lakes: Water Quality Assessment and Object...

    This study quantifies the inputs of phosphorus from various sources and determines the extent to which additional phosphorus could be tolerated by each lake without a serious decrease in water quality. Based on this information, appropriate land uses and...
  • Deception Lake Survey 1982

    This lake survey evaluates Deception Lake. Elements included are the location, physical characteristics, and water quality of the lake, the species present, and the surrounding anthropogenic activities.
  • Consequences of Unregulated Release of Raw Acid Mine Drainage into the Bulkle...

    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...
  • A Reconnaissance Survey of Toboggan Lake

    This survey data includes information regarding the location, physical data, terrain features, water chemistry and temperature, obstructions and pollutions, miscellaneous, netting results, stomach analysis, resort and campsite, habitation, access, oxygen,...
  • A Reconnaissance Survey of McQuarrie Lake

    This survey collected information about the fish species that are present in McQuarrie Lake, as well as information about the physical characteristics of the lake. This included oxygen and temperature profiles, water chemistry data, obstructions,...
  • A Check of How Well Water Quality Objectives Were Achieved in 1986

    Provisional water quality objectives had been set in 18 water basins up to February, 1987. In 1986, water quality data relevant to objectives were collected in 14 of the water basins and these data are evaluated in this report. Although the quantity of data...
