Canada - October 12th, 2010

Thick brown sediments pour out of rivers along the southeastern coast of James Bay, part of Hudson Bay, near Akimiski Island, in Canada. The sediments are densest and darkest brown by the rivermouths, becoming golden tan and then green in color as the bay’s waters dilute them.

From northwest to southeast, these rivers are: the Albany River, the Attawapiskat River and the Moose River. In the full image, they all appear as navy blue lines surrounded by braided green channels.

The Albany River is 982 kilometres (610 mi) long; at the end of its course it empties into the Akimiski Strait on James Bay via a series of channels. The river is navigable for the first 400 kilometres (249 mi).

The Attawapiskat River travels a distance of 748 kilometres (465 mi), and has a drainage area of 50,500 square kilometres (19,498 sq mi). The Moose River’s full length is 547 kilometers (340 mi), its drainage basin is 108,500 km² and it has a mean discharge rate of 1370 m³/s.
