Overview

The Kokish River Hydroelectric Project will include:

  • A low level weir, intake and fish ladder, located approximately 0.5 km downstream of Ida Lake, just downstream of the confluence of the Bonanza River and the East Fork Kokish River
  • A 9 km buried pipeline that, for most of its length, will follow forest roads on the east side of the lower Kokish River
  • A powerhouse and switchyard (occupying 1 to 2 hectares) located near the Telegraph Cove Road and Beaver Cove railway bridges
  • A short section of tailrace channel for return of diverted water to the river downstream of the powerhouse
  • A clear span bridge over the Bonanza River at the outlet of Ida Lake, at the site of a former bridge crossing
  • A 500 m section of 138 kV transmission line between the switchyard and the existing BC Hydro transmission grid
