Water monitoring data for Osoyoos Lake collected by OLWQS:

Each week between May and October, a crew of Society volunteers go out on the lake and test the water for temperature, depth, dissolved oxygen, pH, specific conductivity, and water clarity (secchi disc). Results are sent to the BC Ministry of Environment.

The following are spreadsheets from five locations on Osoyoos Lake for 2006 to 2008. Click the tabs along the bottom of each page to see graphs and charts for temperature, dissolved oxygen etc. Please contact us if you require data from previous years.
