The Mamquam River is a c.35 km (c. 21 mi) tributary of the Squamish River.[3]
The Mamquam River originates at Mamquam Pass and starts off by flowing northwest for about 7.5 km. Shortly below its source, the river picks up the waters of the stream draining November Lake. The river, after about 7.5 km, turns north and continues in that direction for about 6.9 km to its confluence with its second named tributary, Martin Creek. At the mouth of Martin Creek, the river turns southwest for about 5.4 km to the mouth of Skookum Creek. At the mouth of Skookum Creek, the river turns west and flows that way for about 12 km all the way to its confluence with the Squamish River in Squamish. Its other main tributaries, Ring and Mashiter Creeks, enter near the river's mouth.
