16.35: Part of the Lower Churchill River After the Churchill Diversion

As part of the hydropower strategy for Manitoba, Manitoba Hydro decided to divert a proportion of the flow of the Churchill River into the more southerly Nelson. Shown here is part of the Churchill River 1 downstream from the diversion after it was completed in 1976. This photo has a much larger scale than figure 16.34, so the small lake 7 on figure 16.34 is much larger on this photo 2. Also, details of the bends on a small tributary stream 3 can be seen.

Reduction in the discharge of the Churchill has produced several changes compared to figure 16.34. A large sand bar 4 is now above water level—small gullies drain from it down to the river 5—whereas on figure 16.34 it was at or below water level. Similarly a sand bar attached to an island 6 is now above water level, and dark-toned trees 7 are growing on it.

At the large scale of this photo it is possible to see details of the open lichen woodland; dark-toned coniferous trees with triangular shadows can be seen over much of the area 8.
