• Water Control Regime and Anticipated Effects
• above the weir, water level consistent and
  within the historic low and high levels.
• however, this regime to significantly alter the
  character and flow at Quetico Rapids, 1 km
  upstream. (not seen here.)
• downstream of the weir, i.e. over the existing
  waterfall, flow to be very significantly reduced
  and at times almost nil.
