For those details, see links above (March 2019).

No results listed for your inland Ontario lake? We might need a volunteer in your area! Could it be you? Find out more about the program here: Lake Partner Program – OVERVIEW


September 2017 – Secchi Trends Across the Province (PDF, 2 pages) – Read the new fact sheet from the Lake Partner Program and FOCA, about water clarity and the role of the Secchi Disk!

Key findings: while Secchi depths of the majority (65%) of lakes studied between the years 2000 and 2014 did not change significantly, over the last 10 years there has been a 19% decline in the number of Secchi depth readings collected per year. This is concerning. Read the fact sheet to find out what you can do to help!
