ACKNOWLEDGEMENTS
The following people are gratefully acknowledged for contributions of information and assistance during this study:
Ministry of Environment, Lands and Parks
Les Swain, P. Eng., Contract Manager, Water Quality Section
MacDonald Environmental Science
Ltd.
Don MacDonald, Water Quality Specialist
Les Swain provided a list of federal and provincial government contacts throughout Canada presently involved with the development of water quality guidelines. Don MacDonald provided a summary of temperature guidelines recently completed as a compendium for the federal government, and offered advice on the direction of guideline development to address future land-based development concerns. The contributions of both gentlemen are greatly appreciated. A critique of the draft guideline by Colin Gray and Cecilia Wong, Environment Canada and Ian Birtwell, Fisheries and Oceans Canada greatly improved the document. Our thanks for your insights and comments.
