3.34: Part of the Saskatchewan River Delta in Cedar Lake

This complex of river channels, lakes, and marshes is part of the Saskatchewan River delta where the river enters Cedar Lake from the northwest. The main channel of the Saskatchewan River 1 runs southeast through the centre of the photograph; numerous distributaries branch off from it including two that are named Baptising Creek 2 and McKenzie Creek 3. The photograph illustrates the usefulness of air-photos as historical records; it was taken in 1953 when the area was in its natural state, long before the construction of the Grand Rapids dam near where the Saskatchewan River flows into Lake Winnipeg. The dam raised the water level in Cedar Lake so that recent maps of the area show much of the 1953 marshy land covered by water.

The main water channels, heavily laden with sediment, are light-toned 4, whereas lakes are mainly dark-toned 5 except where the water is shallow 6. Dark-toned wooded levees 7 follow the main channel. Marshy areas are light-toned 8, but there are some dark-toned areas of floating fen 9. The circular darker-toned areas 10 in the light-toned lake—the northwest part of Cedar Lake—are probably patches of aquatic vegetation.
