Dangerous Ice
Pay attention to warning signs

Frozen lakes in winter can be inviting for a walk-about. Frozen lakes can be dangerous. Here are some winter ice safety tips and things to remember when venturing in Muskoka this season. 

Ice Danger

Be Prepared on thin Ice
  • remember—ice doesn’t freeze at a uniform thickness
  • near-shore ice is often much thicker and safer than ice farther out, especially at the start of the winter season
  • watch for open water near the shore created by dock bubbler systems
  • check thickness regularly with a spud bar or auger as you move farther out
  • ice that formed over flowing water, springs, pressure cracks, old ice holes or around the mouths of rivers and streams can be weaker than surrounding ice
  • Keep an eye out for Ice Shoves/Pressure cracks that appear on the lakes

Colour Of Thin Ice

Colour of Ice
Don’t go near the ice.
  • clear blue/black ice is the strongest
  • white or opaque ice is much weaker
  • grey ice indicates that water is present and ice may be weak or slushy
  • stay away from ice that looks honeycombed, common during thaws or in the spring

Driving on ice

Driving on Frozen Lakes
  • be careful when driving snowmobiles or vehicles over frozen lakes or rivers
  • People need at least 10 cm and snowmobiles need at least 20 centimetres (8 inches) of clear blue ice
  • double the thickness if the ice is white or opaque
  • Avoid driving at night and in areas you are unfamiliar with
  • heavy snow on a frozen lake or river slows down the freezing process
  • If traveling in an inclosed vehicle leave doors unlocked, windows down, lights on and seatbelts off to facilitate a quick escape. Do not wear a lifejacket or floatation suit while inside as these may hamper escape 
  • Do not drink and drive

Be Prepared

Ice Safety
Safety Gear for being on Ice
  • check ice conditions either with local ice hut operators, bait shops, snowmobile clubs or by cutting holes in the ice in various locations  
  • let others know where you’re planning to fish or ride and when you plan to return
  • wear appropriate clothing and equipment for safety and comfort. This includes a floatation suit, ice picks, helmet, insulated clothing
  • Carry safety equipment with you including rope, pocket knife, compass, whistle, fire starter kit and cell phone

Private Buoy Regulations

Safe Boating on the Muskoka Lakes Private Buoy Regulations are for thoseMarker Buoy whose cottages are located in busy boat traffic areas, therefore it is a good idea to set out private buoys to remind boaters of the rules of speed and safe distance from shore.

If you do, be sure you are adhering to the following regulations.

Private Buoy Regulations: Canada Shipping Act

Statutory Orders and Regulations (SOR) 99-335

1. In these Regulations, “private buoy” means a buoy that is not owned by the federal government, a provincial government or a government agency.

2. These Regulations apply to every private buoy other than private buoys used to mark fishing gear.

Keep a Safe Distance

3. No person shall place in any Canadian waters a private buoy that interferes with or is likely to interfere with the navigation of any vessel, or that misleads or is likely to mislead the operator of any vessel.

The Muskoka Watershed

The Basin

Bracebridge Falls in Spring
Bracebridge Falls in Spring

Water is Muskoka’s most valuable asset. Lake Muskoka is part of a large watershed called the Muskoka River Watershed. The Muskoka River Watershed covers a large area on the eastern side of Georgian Bay. Its headwaters are found on the western slopes of Algonquin Park. The Flow is southwesterly for a distance of approximately 210 km. It discharges into the southeast corner of Georgian Bay. The watershed basin encompasses many of Muskoka’s most well known lakes including Lake of Bays, Mary Lake and of course Lake Rosseau, Lake Joseph and Lake Muskoka.

The Watershed Area

Muskoka Watershed
Muskoka Sub-watershed

The watershed measures over 62 km at its widest point and is approximately 120 km long. It encompasses an area of approximately 4,660 sq. km. The watershed is divided into three drainage areas, the North Branch, South Branch, and Lower Muskoka. The North and South Branches make up the eastern two-thirds of the watershed. The Lower Muskoka sub watershed covers approximately the western one-third of the watershed. It receives the inflow from both the North and South Branches as well as Lakes Joseph and Rosseau. This combined flow passes through the Moon and Musquash Rivers and discharges into Georgian Bay.

2,000 Lakes

There are over 2,000 lakes within the watershed area covering about 17% of the total basin. They are what makes Muskoka “Cottage Country”. Hundreds of thousands of visitors and recreational property owners come to the region to enjoy the beauty. The Muskoka River descends approximately 345 metres in elevation along its 210 km journey from its headwaters to its mouth at Georgian Bay.

Watersheds are nature’s way of cleaning our environment, they have three primary functions: to capture water, to filter and store water in the soil and to release water into a water body. You could think of a watershed as a giant sponge. As precipitation falls, it is stored in the watershed’s land and water bodies and slowly released through shallow water discharge into the river.

Why Does it Matter

Why is understanding the watershed important, you may ask? Well, as all living things in our region, including us humans, depend upon this ecosystem we need to be invested in its well being. The effects of forestry, agriculture, industry and urbanization are all recorded in the water as it flows along its path. For better or worse, each tributary stream, wetland or spring which joins together reflects the health of the region.  We need to make sure our footprint on it is minimal.

How can you be a positive contributor to its well being? By doing little things like selecting phosphate free detergents and cleaners if you are on a septic system. Make sure your septic is inspected regularly and serviced when needed. Using all natural insecticides and pesticides in your garden and making sure your boat motor is well tuned up and not leaking oil and fuel into the lake.

Water is Muskoka’s most valuable asset. I am sure you can think of more ways to preserve this beautiful region. If we all take on the mind set of caring to protect what we all value, it will be here for future generations. There is a great deal of information about all things to do with our waterways including information about the Muskoka Watershed.Muskoka WaterWeb

Winter Ice Safety

Winter Ice at Your Muskoka Cottage

We all know the quote from Shakespeare is actually “double double toil and trouble,” but those who do not want the “double trouble” of ice damage on their docks are likely to look into installing a bubbler or agitator system to protect waterfront structures at their Muskoka cottage.

If that is you, be warned that there are some serious considerations to make before you decide whether to install one. And if you do, it’s important to know how to properly manage it.

The decision to install a bubbler or agitator is often made based solely on protecting the often very large investment made in creating wonderful docks and boat house structures at the shoreline or our waterfront properties. We have all heard the stories of the dangers a dock bubbler has on people, snowmobilers, and even pets. Transport Canada has this on its site: “Note: The action of safeguarding the ice and the hole that is created is a criminal code responsibility. It falls under the Criminal Code under “Duty to safeguard opening in ice”. Any questions regarding the marking of the opening in the ice should be directed to your local OPP detachment.”

In addition, did you know that while a bubbler is protecting your property, there are many instances in which a dock bubbler can cause intense damage to a neighbour’s dock and boathouse? This is not only going to cause an issue with your neighbour, but it also adds to the wooden debris on the open water resulting in a hazardous situation for boaters. There is an increasing amount of evidence that using a bubbler/agitator has a negative effect on hibernating animals in the area and by keeping large areas of water open and subject to the warming effect of the winter sun, it is thought that overall lake temperatures will increase, affecting the whole eco system of the lakes.

The purpose of a bubbler or agitator is to create an open water buffer between the structure and expanding/contracting ice. A five-foot ribbon of open water or thin ice around the front and down the sides of the dock is usually all that is necessary to minimize damage from contraction and expansion. Satellite images of the lakes in Muskoka reveal that many systems are keeping more than twenty feet of water open and in some smaller bays, where several owners have systems, the entire bay is being kept open. What you may not know is that, using a bubbler won’t help is during spring break-up. This is when the majority of severe damage occurs. Ice usually melts around the shoreline first, which means that most lakes will have a 20 to 50 feet open area around the shore. Nothing is going to prevent huge slab of 5” thick ice moving at 1 mph from doing severe damage to you dock at this stage…no matter how many bubbles are still blowing. So if it’s a windy day when the ice starts to break-up and move around, it sometimes comes down to a matter of luck.

The decision to create some rules for the use of bubblers has been made at the Township of Lake of Bays. Muskoka Lakes and other area Townships are in the process of deciding on what rules and method of enforcement they will put in place. It is very difficult for our Townships to enforce anything at all as the legal mechanism for enforcement of activities on a waterway is not part of their mandate.

Here are some “Best Practices” for the use of a bubbler/agitator system taken from a list created by the Lake of Bays Association for its members.

1. Place/angle your device properly. If an agitator is used, be aware that angling it toward the shore directs the flow inwards and not out into the lake, minimizing the amount of open water created.

2. Install a timer and/or thermostat. Operating your ice-away device 24/7 from fall to spring can result in excessive open water. Eight to 12 hours per day is usually sufficient at Lake of Bays to maintain an appropriate amount of open water around your structure. Using a timer and/or thermostatic switch also reduces energy consumption and saves you money. Unnecessary running time can also be controlled by setting a thermostat control that switches the device off if the air temperature is above freezing.

3. Mark open water with warning signs / lights display signage to alert others to the potential danger of open water. These red and white signs are available at most hardware stores in the area or where ice-away devices are sold. However, signs will not prevent animals from falling in; some property owners also put yellow warning tape and fencing around the open water. At night, the snowmobile community recommends displaying a flashing amber light because it signifies caution. A red light can be mistaken for the taillight of another snowmobile and bright white strobe lights are offensive to neighbours.

4. Monitor your property. If you are not using your property in the winter, have it checked periodically to ensure your ice away-device is working properly and that your warning sign(s) and lighting are in place. Turn your device off when / if the water levels are lowered in your lake (usually March).

5. Be ice smart. No ice is without risk. Snowmobilers, skiers, skaters and hikers should exercise caution while on the ice and stay well clear of docks and boathouses. It is clear there will be more debate on this matter and we hope we have informed you a little.
