Cowichan Lake Level

March 14, 2019 by Jill Thompson

This chart shows the water level in Cowichan Lake for the previous 18 months. It is usually kept up-to-date to yesterday.

The chart comes from the Water Survey of Canada which maintains five automated stations within the Cowichan Watershed. The Cowichan Watershed Board provides a portal to the WSC on the Discharge Charts page.

This chart has four main areas, which are described here:

In the centre, is the 18 month chart showing the seasonal rise and fall of Cowichan Lake. The line is made up of the daily average of measurements from the automated station. The level is given in metres above sea level. 162.37 metres is the top of the weir.

On the left, is a photo of the gauge mounted on the weir. It uses the Imperial scale in feet, with the zero at 162.37 metres above sea level.

On the right, are five significant levels that are of concern in the annual management cycle of the lake and the river flow. Also on the right are the names of the three water gauges displayed on this chart: the lake where we care concerned with water level, the river directly below the weir, and the river near Duncan.

On the bottom, are the most recent metrics, as well as peak highs and lows for the last three seasons.
