As you know, there was no water sampling program on account of the pandemic. But your group of lake volunteers were still collecting transparency data so that we now have charts of our four lakes with 14 years of data (average transparency) presented in the following charts.
Transparency in itself is a good indicator of a lake’s health. But water sampling, especially for the detention of phosphorus levels, is essential, We will thus resume the water sampling program this year.
Let us start with Black. It’s replenishment rate is 1.9 years which is normal. But it is a small lake and it’s plant’s cover has evolved significantly in the past years. Last year the purple bladderwort cover had been reduced by almost 80%!
Each lake has it’s own personality as sometimes reflected in it’s name Black’s water is quite coloured. Clear is the opposite with very transparent water. Curran is the largest lake and it’s numbers show little variation over the years.
As you will see, the variations are greater in our smaller lakes. In Boyd’s case, there is s easy explanation. The replenishment rate is very high (0.5 years) so there is more turbulence. And Boyd gets tons of water from Black. The opposite is true for Clear (1.9 years) and Curran (2.37 years).
That being said, we should absolutely make sure that every septic system is in top shape, that sources of run off are eliminated and that shoreline protection bands are robust. These rules are spelled out very clearly in the Living in Dunany document. If you need help or advice, contact us.
Finally, a quick reminder about beavers. Some have already been spotted so, if you have valuable trees on your property, even if they are pretty far from the lake, do protect them as shown on this page. Beavers will always be with us.
