Science Advisory Report 2013/061
Advice on the Standardized Data Collection Methods in Support of a Classification Protocol for the Designation of Watercourses as Municipal Drains
Summary
- Watercourses designated as municipal drains are currently classified based on temperature, permanency of flow and fish species present. Proper drain classification is imperative to ensure that appropriate mitigation is used during drain maintenance works.
- Information related to drain segmentation, as well as sampling protocols to determine temperature, permanency of flow and fish species present to ensure that drains are properly classified is provided.
- Advice on sensitive species criteria, as well as a classification method to determine whether a species should be classified as 'Sensitive' or 'Tolerant' is discussed. Following the proposed classification criteria, all fish species in Ontario were classified as either 'Sensitive' or 'Tolerant' [refer to Appendix 1 of Mandrak and Bouvier (2014)].
- Guidance is also provided on proper vouchering techniques, including both preserved vouchers, as well as digital vouchers. A list detailing vouchering requirements for all species in Ontario is provided [refer to Appendix 2 of Mandrak and Bouvier (2014)].
This Science Advisory Report is from the July 11, 2013 Science review of standardized data collection methods in support of a municipal drain classification sampling protocol. Additional publications from this process will be posted as they become available on the DFO Science Advisory Schedule.
