About
Quamichan Lake is a lake in the Cowichan Valley region of Vancouver Island, British Columbia, Canada, located three kilometres to the northeast of the City of Duncan.
Quamichan Lake and its sister Somenos Lake were created 11,000 years ago by receding glaciers. Both lakes contribute to Cowichan River. Quamichan Lake's outflow is Quamichan Creek which joins with Somenos Creek, the outflow from Somenos Lake, which flows to Cowichan River.
The Cowichan Watershed Board identifies a common set of conditions for both shallow lakes:
excessive nutrient loading from the farms and homes which surround the lakes
insufficient "flushing" in summer due to reduced inflows and truncated outflows
