Notice of permit
Regional or Local Number: DFO-17-HQUE-00111
Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-17-HQUE-00111 is issued.
Activity affecting the species is incidental to the carrying out of the activity
The Windsor dam is located on Saint-François River near Windsor. Repair work on the dam’s inflatable bladders is required and involves lowering the water level upstream and downstream of the dam for a maximum of five weeks. The work will be performed between July 31 and September 29, 2017. To minimize the effects of lowering the water level on the Channel Darter during the drawdown, fish that have been unable to reach the main channel of the river upstream and downstream will be caught and relocated to the part of the river where there is still running water. Fish must be caught gently, beginning when the water level is lowered. Visits will need to be performed throughout the drawdown.

Location of Activity (province, territory or ocean):
a) Alternatives were considered and the best solution was adopted. The dam’s inflatable bladders can be repaired only by lowering the water level upstream and downstream, which will temporarily empty some of the river upstream and downstream. b) Measures will be taken to mitigate the negative impacts of the activity on the species and its habitat. The water level will be lowered gradually to allow fish to reach the main channel. An instream flow will be maintained on the left bank to provide water to a portion of the river. On the right bank, the river will flow through the five turbines of the hydroelectric generating station with an evacuation capacity of 90 m3/s. The work will be of short duration (maximum five weeks). The fish will be caught in a seine or dipnet and transported in pails. The water in the pails will come directly from the waterway. With these methods, there should be no fish mortalities. Other fishing gear such as electrical fishing and gillnets were considered, but were not selected because they could cause mortalities and are not always effective for catching the Channel Darter. c) Taking into account the mitigation measures that will be implemented, the survival and recovery of the species will not be compromised by this work, since no fish mortalities are anticipated and the temporary drying of the habitat will not significantly affect the life cycle functions of the Channel Darter.
