UPDATE: March 2019 – the Lake Partner Program’s province-wide sampling results from 2018 are now available! Download data results below:
- Total Phosphorous results (Excel)
- Average Secchi depth results (PDF, 14 MB) Average Secchi depth results (Excel)
- Calcium results (PDF, 9 MB) Calcium results(Excel)
Contact the Lake Partner Program Coordinator if you cannot access your lake’s results.
Find out if your lake is being sampled and if so, review past results on the interactive online map (pictured above) which is maintained by the Ontario Ministry of the Environment and Climate Change. NOTE: the most recent data results (2018) have NOT YET been incorporated into the online map. 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!
