Lake Water Quality

I was rifling through some old files yesterday and came across a couple of newspaper articles from 1993 about clear lakes in Ontario. Definitely not a recent account, but interesting all the same. I have always maintained that Haliburton Highlands has amazing, clean, clear lakes. We are located above the Trent Severn Waterway system so we aren't as subject to invasive species and pollutants, and we have lots of natural rock - one of nature's built-in filter systems
. The article supported my theory.
Written by Peter Janas, B.Sc.F., the article references results of a study that Mr. Janas completed. The article explains what is meant by "clear" and how it correlates to lake depth, amount of algae, etc. I won't go into detail of his study, as I am not a researcher and do not want to get any of the accounts incorrect, but what I did like was the number of Haliburton Highlands lakes that were on his "Clearest Lakes" in Cottage Country.
What lakes were they? Hall's Lake, Big Hawk Lake, Boshkung Lake, Mountain, and Twelve Mile Lakes (all along Highway 35's corridor), Billings Lake and Allen Lake (on the Eastern side of the County), Kennisis and Haliburton Lakes (north of Haliburton Village), and Miskwabi Lake, about 15 minutes East of Haliburton Village.
One point that Peter Janas makes is that "clear" often correlates to depth - and each of these lakes are deep lakes that provide excellent lake trout fishing, but we are so blessed in the Highlands with 600 lakes of every size and depth - something for everyone. What a great place to live and play!!!
