Attached are the water quality tests for Ivry this year. The The Ministère du Développement durable, de l’Environnement, de la Faune et des Parcs (MDDEFP) preformed water test in our lake in 2008, 2009, 2010 and determined our lake to be Oligotrophic. An oligotrophic lake is a lake with low primary productivity, the result of low nutrient content. These lakes have low algal production, and consequently, often have very clear waters, with high drinking-water quality. The bottom waters of such lakes typically have ample oxygen; thus, such lakes often support many fish species, like lake trout, which require cold, well-oxygenated waters.
The actual results can be found at the following address http://www.mddefp.gouv.qc.ca/eau/rsvl/rsvl_details.asp?fiche=368.
The AALM also performed its annual water test to determine the fecal count in multiple locations around the lake. The results this year were excellent in all areas.
