When I first read our 2015 Reports from the Volunteer Lake-Monitoring Program (VLMP) – yes they now have an English name and page – the lyrics of Frank Sinatra’s wonderful classic It Was a Very Good Year came to my mind. Listen to the first few bars if you wish!
The weather last summer was OK and our numbers are there to prove it. Clarity is much better. Phosphorus count (micrograms per litre) is way lower. 3.5 on Black, 3,9 on Boyd, 2.9 on Clear and 3.1 on Curran. Thus, all of our lake are in the oligotrophic* category.
Do take a minute to have a look at the Reports.** There are two of them for each lake . One – the sa-su – give you the 2015 results. The other one – pcp – is the multiyear chart; definitely the most interesting as you can see the trend.
These numbers are very good but – there is always a but – they have limitations as we only take three samples each summer at a depth of one meter, always at the deepest spot of the lake as per the official protocol.
That being said, we now have 10 full years of data that show almost continuous improvement in the quality of our water, we can have more confidence in the reliability our our data.
Bottom line: you all deserve congratulations for good lakeside behavior. Keep it up: make sure your septic system is in good working order and regularly cleaned.
Continuously reinforce your shoreline protection band. Do not use pesticides and fertilizers anywhere near the lake and make sure your property is well drained to limit runoff.

Finally, we wish to thank our dedicated collaborators on each lake. John Parsons on Black, Rick Havill on Boyd, François Côté on Clear and Sheryl Jacksom-Caron on Curran. This year, Jim and Lois Finch will take over on Black. Thanks John for all you have done during all these years.
* An oligotrophic lake is characterized by a low accumulation of dissolved nutrient salts, supporting but a sparse growth of algae and other organisms, and having a high oxygen content owing to the low organic content.
** The Reports are only available in French at this time. Numbers are different from last year’s but not the text which you can read in English in 2014 Lake Reports..
