Since 2002, the BC Lake Stewardship Society has coordinated BC’s participation in the North America-wide annual Secchi Dip-In. This year, 23 volunteers completed 30 dips on 28 lakes. We had several volunteers that submit dips for multiple lakes in their area. Since 2010, there has been a 47% decline in the number of lakes with Secchi depth readings collected during the BC Secchi Dip-In. This is concerning because long-term trends are important indicators of the changes a lake is experiencing. These long-term data sets are valued and without them it is difficult to track trends.
Please encourage others to take part in the 2019 Secchi Dip-In. If Secchi depth is measured in a lake routinely for many consecutive years, the data can be analyzed for trends in water clarity. This could be valuable for examining the effects of climate change.
To become a dipper for the 2019 Secchi Dip-In, please contact the BCLSS office. An email reminder with instructions and data sheets will be sent out in the spring.
