Navigation

Image: Environmental follow-up
The follow-up will consist in assessing motorboating, canoeing and kayaking conditions in the Rupert, Lemare and Nemiscau rivers, Rupert diversion bays and Boyd and Sakami lakes. Hydro Québec will monitor flow and water levels in modified water bodies before and after diversion. Corrective measures will be implemented as needed to ensure that the streams remain navigable.

A 29% instream flow will be restored to the river downstream of Rupert dam The instream flow will reduce the drop in water level below Rupert dam so that the river remains navigable.
Eight hydraulic structures will be built
 The hydraulic structures will raise the water level and improve navigability in stretches controlled by weirs.
A safe detour will be built around work areas Construction work in the water will interfere with navigation.
Measures to make the diversion bays navigable and safe:
  • Navigation corridors will be cleared
  • Boat ramps will be built
  • Portages will be created near structures
  • Signs will be set up near structures
  • Booms will be installed in the Rupert River upstream of the transfer tunnel and spillway and in the Lemare River above the instream flow release structure
 Creation of the diversion bays.
Measures to make the reduced-flow section navigable and safe:
  • Boat ramps will be built
  • Portages will be created
  • A navigation chart of the river will be produced
The instream flow and eight hydraulic structures will ensure that the entire reduced-flow section of the Rupert River remains navigable. However, routes will be changed in river stretches not controlled by hydraulic structures.
Measures to facilitate navigation and shore access in the increased-flow section:
  • Wood debris will be collected in cooperation with the Crees
  • A chart of navigation corridors will be produced
The increased flow may cause wood debris to accumulate in certain bays.
