Our priorities are...
Our sampling season began on May 5th
and ran through until Sept. 8th during which we took 13
readings in both the north and south arms at the east end of Lake
Cowichan. Our readings reflected those of previous years with
similar temperatures, excellent clarity & oxygenation levels. The
quality was best in the early spring and decreased over the summer,
although the overall quality was still excellent when we stopped sampling
We are indeed fortunate to live on and around
this great natural resource!
Here are some observations from this years
||12.1 degrees on May 5th
||21 degrees starting on July 28th,
through to Sept. 8th
|Water Oxygenation Level
The higher the number, the better the quality of water.
||8.1 mg/litre of water, on Aug. 11th -
still a very good number!
||10.8g/litre of water, on May 5th
Measured using a device
called a secchi disk. You drop it into the water and measure the
depth at which it is no longer visible. The greater the
depth, the clearer the water.
||10.8 meters (we did have some readings at 14.1
Many thanks to our volunteers who contributed
80+ hours of their summer time to do the work and a special thanks to those
volunteers who provided the boats which make this program possible!!
