Another beautiful month of water testing! The air quality from the smoke may be poor, but the water quality of Columbia Lake is healthy! 

The water temperature reached its peak after the heatwave and has now started to cool down a little. The lake depth is starting to drop significantly now that the fresher (snowmelt) no longer has an effect on the lake. The turbidity, pH and dissolved oxygen are at a good level for the lake.

Thank you to this month’s volunteer Ed Gilmore! He has been volunteering with CLSS ever since the organization was first created!
