Water Quality: Second Report on Chemical Sensitivity of BC Lakes to Acidic Inputs

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 ten lakes with pH less than 6.0 have been found and presents a generalized sensitivity map for the province. A distribution of lakes in the Province by sensitivity indicator is presented which shows that about 20% of the lakes have high sensitivity to acidic inputs. Information is also provided on calculated relationships between total dissolved solids and several characteristics. Relationships with a high level of confidence list for calcium, inflection point alkalinity and alkalinity to pH 4.5.
