Title: Biological survey of the Etobicoke Creek 1962, 1963, 1964
Author: Owen, G. E.; Johnson, M. G.
Abstract: The examination of biological conditions of a watercourse provides information of practical use in assessing water quality and the effect of changes in water quality. Changes in the characteristics of water which adversely affect the amenities of a watercourse are usually associated with alterations in aquatic plant and animal communities. As well, the extent to which these communities are changed indicates the degree of water quality change and reflects conditions in the watercourse over several months Prior to examination. Biological data also provide a useful basis with which to compare future changes in water quality. For these reasons, biological surveys were undertaken on the Etobicoke Creek in 1962, 1963 and 1964.
