Fresh water shapes British Columbia’s landscapes, communities and economies. But this most precious natural resource faces an increasingly uncertain future: with shifting climate and hydrology, and intense cumulative pressures, British Columbia is entering... -
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... -
Acute and Sublethal Copper Sensitivity, Growth and Saltwater Survival in Youn...
A series of experiments was conducted during the spring, summer and fall of 1977 to determine the potential copper toxicity hazard to Babine Lake sockeye salmon (Oncorhynchus nerka) fry, lake fingerlings and smolts. Acute 96 h LC50's were determined for the... -
Preliminary Categorization of the Productivity of 37 Coastal and Skeena River...
We carried out limnological surveys of 37 lakes on British Columbia's north coast and Skeena River system. Limnological data collected on these surveys enabled us to make preliminary estimates of the lakes' trophic status and productive capacity for... -
Chemical Studies of the Recent Sediments of Babine Lake British Columbia
The multi-disciplinary Babine Watershed Change Program (1973) was initiated in 1971-1972 by the Department of the Environment to assess effects of environmental change on Babine salmon and trout production. The program includes paleolimnological studies to... -
