Muskoka. Our environment is far more than our economy.

From the Muskoka Watershed Council Lecture Series I have just finished editing and have just posted this video on the Muskoka Watershed Council’s YouTube page.

All of us should be familiar with the fact that in Muskoka, our environment is our economy; over half our GDP comes from tourism and cottaging. In this lecture, Peter Sale attempts to convince us that our environment is far more than our economy.

Every year some 5 billion cubic metres of water pass through Muskoka – that’s 3 1/2 times the entire volume of Lake Muskoka. Half is evaporated or transpired by Muskoka’s forests and plants, the other half – some 2.5 billion cubic metres flows into Georgian Bay. As climate change affects Muskoka – producing warmer and wetter winters, but dryer summers with more intense storms – we may be trying to find ways to hold on to that water, just a little longer; maybe the beaver has a solution for us.

Peter, who describes himself as a strange, but harmless ecologist, talks about some of the many creatures in Muskoka including the beaver, the expected effects for Muskoka from climate change, an idea or two on solutions, and that there are other ways of valuing our environment other than simply to value it as a storehouse of resources to dig up and take away.

Algae and Water Quality. Looking back to see the future

As mentioned in previous posts, cottage owners and cottage buyers want to know about water quality on lakes in Muskoka. Because water quality has a direct relationship to property value, and algae – particularly algal blooms – directly affect water quality, we all want to know as much as we can .

I just completed and uploaded a video here for the Muskoka Watershed Council YouTube page. The subject is a talk that was presented by Dr. Andrew Paterson of the Dorset Environmental Centre at the Muskoka Stewardship Conference at Nipissing University in Muskoka (Bracebridge). The event’s theme was What Are You Watching?

This highly interesting talk looks at studying lake sediments deposited over hundreds – and even thousands of years. Sediments are archives of environmental change and within them are clues to possible triggers of algae outbreaks.

Dr. Paterson talks about sediment research done in Lake of the Woods in north-western Ontario and the Hudson Bay Lowlands which may help scientist understand occurrences in the lakes of Muskoka. There is discussion on the relationship between water quality and property value for cottagers. The seeming paradox of stable or even declining phosphorous levels – the usual algal bloom suspect- at the same time as blue-green outbreaks are increasing. And of course, the effect of climate change.

Algal Bloom Three Mile Lake 2005

Of particular note is the 2005 toxic algal bloom in Three Mile Lake in 2005, where research may indicate the possible triggers of record high temperatures coupled with record low precipitation which occurred in the fall of 2005 in Muskoka.

There is significant evidence that a warming climate is related to the increase in algal blooms. Dr. Paterson suggests that if algae was the music that we hear from a radio: then phosphorous is the volume; other nutrients (particularly nitrogen), light, etc., influence what species are present – are the “tuning”; and climate is the antenna. The presentation concludes that blue-green algae likes it hot!

Sparrow Lake Fishing Derby & Picnic

We have hosted these two events in the past on behalf of the Sparrow Lake Association. I am glad to see it continue; also to see that the fishing derby continues to be catch & release.

We urge all Sparrow Lake and Severn River residents and visitors to join the SLA and enjoy these events as well as the annual Regatta. The SLA does important work to protect your investment in, and enjoyment of, this wonderful area.

Here’s a link to download the Sparrow Lake Association brochure.

Message from the SLA President

Please join us for the annual Sparrow Lake Association Fishing Derby and Picnic on July 6, 2013.

The fishing derby starts at 10:00 a.m. and ends at 11:30am–no fishing license is required as it is Free Fishing Week in Ontario. All ages are welcome to fish but only children 14 and younger are eligible to win prizes. You are required to hand in an entry form at the end of the Derby to be eligible for prizes. This is strictly a catch and release tournament and tracking of fish caught is on the honour system, as witnessed by an adult. Entry forms will be available at the Franklin Park Dock (adjacent to Silver Pines) prior to the start of the Derby or can be downloaded from our website http://www.sparrowlakeassn.com/fish.html

The Picnic starts at 12:00 Noon on the back lawn at the Silver Pines. The cost is $8 per person for: (1) the choice of a Hotdog or Hamburger; (2) a cold drink; and (3) ice cream. There will be activities  for the children afterwards. Please RSVP by July 3, 2013 and let us know your preference for a Hamburger or Hotdog. You can RSVP by phone 705-684-9241 or by completing the electronic form on our website http://www.sparrowlakeassn.com/fish.html  

We hope to see you all at the SLA Fishing Derby and Picnic.  If you have any questions, please let me know.
