Hudson Bay drainage basin
The Hudson Bay drainage basin is the drainage basin in northern North America where surface water empties into Hudson Bay and adjoining waters. Spanning an area of about , the basin is almost totally in Canada (spanning parts of the Prairies, central and northern Canada), with a small portion in the United States (in Montana, the Dakotas, and Minnesota). The watershed's headwaters are in part on the Continental Divide of the Americas, and the watershed's connection to the Labrador Sea is at the Hudson Strait's mouth between Resolution Island in the Qikiqtaaluk Region and Cape Chidley on the Labrador Peninsula. On the Continental Divide the basin is bounded at Triple Divide Peak to the south, and Snow Dome to the north.

Saanich Inlet, at the southern end of Vancouver Island, Canada, is a naturally hypoxic basin. A shallow sill (70 m) at the mouth isolates the deep basin (215 m) that experiences seasonal deep-water anoxia as a result of high primary productivity and subsequent degradation of sedimented organic matter. The Saanich Inlet network consists of cabled arrays of instruments in Mill Bay, Patricia Bay and an autonomous mooring at the entrance (sill) to the inlet. Two cabled surface buoys are connected to the Patricia Bay installation, supporting a technology testbed facility (Patricia Bay) and a full water column observation station (Coles Bay). Patricia Bay installations include:
