Abandoned Dock Clean Up 

PaBIA needs your help! We are hoping to engage our community to help identify and assist in the removal of unsightly and potentially very dangerous abandoned docks on our shorelines. The Township of the Archipelago has agreed to waive disposal fees and help disassemble the docks once delivered to the station.

If you know of any derelict docks please send the specific location and, if possible, a photo to Tom Lundy.

Please keep in mind some docks may belong to American cottagers who have been unable to come to their properties and we must not include these! To avoid this possibility, if you know of any derelict docks, please take a picture and send it to your American neighbours for possible identification before reporting it to Tom Lundy!

VOLUNTEERS NEEDED - Sign Up by calling Marine Patrol - (647) 545-9283

Bruce Tiffin, PaBIA’s Cottage Patrolman, will provide a cottage patrol visit for PaBIA’s US and International members who are unable to be in Pointe au Baril again this year.

This special service is BY REQUEST ONLY.   To have your property on the Summer Patrol, contact Nancy Rogers. Deadline for patrol requests is Friday, August 27th.
Before closing at the end of the season, please attach your patrol tags to your main cottage and any other buildings for which you’re purchased extra tags for the fall ’21, winter and spring ’22 patrols.

TOA Asking for Proper ID Pass at Transfer Station
TOA Logo
Please be advised that the Township has asked staff at our transfer station to request proper identification before depositing your waste. This has become a necessity as folks from outside Township of the Archipelago area, have been using our transfer station.

If you are in need of a new pass please call the township office, at (705) 746-4243. They will email you one for use on your phone. A copy of your tax assessment or Hydro bill will also suffice as identification.

Please remember these folks are only doing their job in asking you for proper identification.

Last Stage for Gypsy Moth (LDD) Control
by Sandy Boeckh

Please note that Gypsy Moths are now being called LDD (lymantria dispar dispar) moths
While there are still some male moths being captured and killed by your LDD moth traps, it is time to move onto the final stage for control - scraping egg masses. (By all means, keep your LDD moth traps baited for as long as you observe the male moths flitting about your property!)
Last Stage Gypsy Moth
This final egg scraping stage lasts until next April or May when the caterpillars hatch. As you can see from the picture, egg masses are thumb size and a pine tree can hold more than a dozen masses or sacs. Each egg mass contains between 100 and 1,000 the math, and you will see how important this stage of control is for next year’s population of LDD moths. Wearing gloves, use a plastic scraper, butter knife or spoon and scrape the masses into a small container. Then, drop all the collected masses into a bucket of soapy water and leave them for 2 days. This will ensure the eggs actually die! Only scrape the egg sacs you can easily reach. If you observe multiple masses on the underside of upper branches, you can use burlap banding next spring/early summer to trap the hatched caterpillars. Good luck!

What Impacts Our Water Levels,
What Does The Future Bring, and
What Can We Do About It?

This week:  Inflow and Outflow
Previous Weeks: Precipitation & Evaporation

by Helen Bryce, Director of Education

The second most influential impacts on Georgian Bay water levels are inflows, outflows, and human-made diversions. Editor's Note: Due to the length, the article about Diversions will be next week. If you would like to read it all at once, please click here.

Great Lakes png
  • Water flows into the Great Lakes from thousands of streams and rivers covering a watershed area of approximately 520,587 square kilometres (201,000 square miles).
  • The flow of water in the Great Lakes system moves from one lake to another eastward, ultimately flowing into the Atlantic Ocean.
  • A single drop of water will take 200 years to move through this system:
  • From Lake Superior, water drains into the St. Mary’s River and flows into Lake Huron
  • Lake Huron and Lake Michigan are connected directly by the Straits of Mackinac
  • Lake Huron waters flow into the St. Clair River, which drains into Lake St. Clair
  • Lake St. Clair, in turn, drains into the Detroit River, and empties into Lake Erie
  • At the end of Lake Erie, water flows into the Niagara River, dropping 52 meters (170 ft) as it flows over Niagara Falls and into Lake Ontario
  • From Lake Ontario, water flows into the St. Lawrence River and ultimately runs out the Atlantic Ocean 
  • But here’s a fact that may be surprising: The Great Lakes are an essentially closed system.
  • Outflows from the Great Lakes are very small in comparison to their total volume: each year, less than 1% of the volume of the water in the Great Lakes flows out the St. Lawrence River.
  • For Lake Michigan Huron, that 1% is equal to the top 1m of water.
  • Perhaps what’s even more impressive than the flow of water through this complex interconnected system is how relatively little water actually leaves the Great Lakes Watershed each year. Great Lakes water is only replenished by 1% annually; the remaining 99% is a one-time gift from melting glaciers
ALSO NATURAL - What is the Glacial Isostatic Rebound?
  • Another reason for elevated water levels is Glacial Isostatic Rebound; the rise of land masses that were depressed by the huge weight of ice sheets during the ice age.
  • Around the Great Lakes, the surface is tilting southward so that land levels in the northern are rising about one foot per century while those in the south are dropping which will have an impact on shipping, recreation and shorelines. 
  • Also, as water levels increase, the added weight in the lake causes the lakebed to sink.
  • This is discussed further in “Rise of Great Lakes Surface Water, Sinking of the Upper Midwest of the United States, and Viscous Collapse of the Forebulge of the former Laurentide Ice Sheet” by Donald Argus.

Next week - the Diversions

by Trudy Irvine, Education Committee

The complex geology of Georgian Bay is endlessly fascinating, and the scales of time and pressure involved are mind-boggling. Islands and shoals on which picnickers now warm themselves are what remains of the roots of the Grenville Mountains of two billion years ago - a range that was as high as today’s Himalayas. Laid bare by millions of years of erosion, covered for a period by sedimentary rock, and then scoured again by ice sheets in past ice ages - the flat, low topography of the resultant Shield rock is now flooded with our lovely Georgian Bay waters. All in all, the timing of our cottaging (geologically speaking) is pretty good.

One interesting geological landform common around Georgian Bay is the “pothole” - a round or cylindrical depression that can be found in all types of rock. Potholes date back to the last ice age when huge volumes of turbulent, fast-flowing waters flowed under and away from the melting ice sheet. Potholes were literally drilled into rock surfaces by boulders that were spun around in turbulent eddies. (Thank you, Nick Eyles, for your wonderful book “Georgian Bay: Discovering a Unique North American Ecosystem” where more information and photos can be found.)

Potholes several feet deep exist on multiple islands in the Pointe au Baril area. The potholes in the first photo are on the second most southerly section of the Georgian Bay Land Trust’s Lookout Island (left pic below). Do you know which one? The smaller pothole is about 2 feet wide- would you be brave enough to lower yourself in the water and find out how deep? 
West Lookout pothole
Chicken Channel pothole
This pothole on the east side of Chicken Channel (pic on the right above) is well known by everyone in the immediate area. Susan Armitage remembers her son Kevin somehow bailing the water out of the hole- maybe with a bucket on a rope. (Well above the waterline on the top of a steeply sloped small island, this pothole is filled with rainwater.) The highlights Kevin remembers include a friend standing deep in the empty hole- and finding several perfectly smooth stones about 4” wide at the bottom. No doubt the stones were the remains of the boulders that carved the pothole into the bedrock themselves. There was a little too much green slime and too many frogs in the hole for Kevin’s sister Kirsten Cooke to consider the same!
Marine Patrol LOGO
Part of the job for Marine Patrol is finding and handling different invasive species. One of those species is Phragmites.

How to Identify Invasive vs. Native Phragmites:
  • Colour: In August, the stems of the native, non-invasive phragmites are red in colour while the invasive phragmites are more of a tan colour.
  • Density: The invasive phragmites are very dense, meaning they’re many and are close together while the native phragmites are not as close together and allow for other plant and wildlife throughout.
  • Flowering Time: The invasive phragmites flower in late July or early August while the native phragmites flower in early July.

If you do come across Phragmites, we recommend leaving them be and reporting the sighting to the Marine Patrol. Please do not cut or pull out the phragmites as this could spread the seed of the plant to other areas of the Bay.

If you have any questions on how to identify phragmites or safe removal of the invasive plant, feel free to contact the Marine Patrol for more information.
