Proceedings of the regional peer review on the effects of water flow management regimes in the Trent River on Channel Darter (Percina copelandi) spawning activities; January 15, 2016
Chairperson: Kathleen Martin
Editor: Kathleen Martin
Summary
A regional science peer-review meeting was held on 15 January 2016 in Burlington, Ontario. The purpose of the meeting was to provide advice on the effects of water flow management regimes on Channel Darter spawning activities in the Trent River (Trent-Severn Waterway), Ontario.
The Channel Darter (Percina copelandi) is a small benthic fish, listed as Threatened on Schedule 1 of the Species at Risk Act (SARA) and under the Ontario Endangered Species Act (ESA). Many of the Canadian rivers that support Channel Darter populations are affected by dams, and the species is considered sensitive to altered flow regimes, particularly during spawning. In the Recovery Strategy for Channel Darter, Critical Habitat has been delineated in the Trent River from Glen Ross to Trenton, Ontario. A habitat modelling study was undertaken to inform setting of minimum flow level or regime recommendations for the Trent River during the spawning period of the Channel Darter and is the basis for this peer review.
Participants included DFO Science and Species at Risk programs, Parks Canada Agency, Ontario Ministry of Natural Resources and Forestry, University of Toronto, University of Guelph and Ontario Power Generation Inc.
This proceedings report summarizes the relevant discussions from the meeting and presents recommended revisions to be made to the associated research document. The working papers presented at the workshop will be published as Canadian Science Advisory Secretariat Research Document. The advice from the meeting will be published as a CSAS Science Advisory Report.
