Reverse delta
Aerial panorama looking across Campbell Lake towards the Mackenzie Delta in Canada's Northwest Territories. While rivers often form a delta when they flow into a lake, the outflow of a lake is usually a single stream. Campbell Lake features an unusual reverse delta. Normally, water drains from the lake into the East Channel of the Mackenzie Delta. But during spring floods when the water level in the Mackenzie River is high, the flow reverses, bringing silt-laden water from the Mackenzie River into Campbell Lake. Over time the silt has built up this reverse delta, filling the centre of the lake and nearly dividing it in two. Panorama stitched from 5 files in landscape format.
