Results of the water testing analyses of our lakes for 2012

Since 2009, our association has actively participated in the Voluntary Lake Follow-Up Network of the Quebec Ministry (www.mddefp.gouv.qc.ca/eau/rsvl). We took water samples in 2009 and 2012 in order to measure and gauge the following indicators of the water quality : total phosphorus, alpha chlorophyll and organic carbon. In doing so, we are actively pursuing a transparent and annual code of conduct. For more information on the aforementioned water indicators, please consult the following site : www.mddefp.gouv.qc.ca/eau/rsvl/methodes.htm

Concurrently, the association makes it possible for numerous members to have their tap water analysed annually for fecal and total coliforms content.

Summary of the test results of our two lakes

The Lac des Sommets is in terms of eutrophication (the over-population of aquatic plants that if unstopped, will eventually choke a lake or stream) a lake that displays weaker physical and chemical qualities than Lac Charlebois. This is not surprising since Lac des Sommets was once a river, appropriated by beavers as well as being quite shallow. The good news, however, is that all these negative elements can be acceptably maintained by responsibly managing and controlling the waste water inflow and shoreline of this fragile lake.

Generally speaking, studies from 2009 to 2012 indicate that the measured quality of the two lakes do not indicate any deterioration of the water quality. We are pleased  to announce that the amount of phosphorus indicators has declined. These phosphorus indicators limit or favor plant growth, algae and micro-organisms, notably cyano-bacteria (blue algae).

Many reasons can explain these results. : inter-annual pluvial variations, reduction of domestic use of phosphorus found in detergents and fertilizers and the amelioration and upkeep of our lakes’ shorelines.

The association has analysed 9 different areas in addition to 22 other analyses by members in 2012 and has concluded that in terms of fecal and total coliforms , the water quality is ideal for recreational purposes.

For more information, you may consult the Ministry’s findings of our lakes. We have grouped these findings since 2009 in this section of our document archives: Tests results and Studies

In 2013, we are continuing to pursue and monitor the health of our lakes by :

1)      Measuring the total phosphorus content of the lakes’ tributaries

2)      Producing a mapping protocol of the lakes’ shoreline and

3)      Continuing the sampling and analysing of the water quality.
