The Water Survey of Canada (WSC) is the national authority responsible for standardized water resource data in Canada. WSC is a function of Environment Canada.
WSC makes available near real-time hydrometric data, which includes discharge rates, water levels and some temperatures. Four stations are in the Cowichan Watershed itself. Three other stations included on this page are adjacent to the Cowichan Watershed: Harris Creek which drains into the San Juan Watershed to the west, Chemainus River to the north, and the Koksilah River to the south. The Koksilah and the Cowichan Rivers together form the Cowichan Estuary, and the two drainages are often thought of as a common watershed.
Each chart represents up to 18 months of data to the recent present. You can update the charts (and explore other features of the WSC facility) by clicking on the stations you are interested in.
