Inspection of Septic Installations

A new program for mesuring septic muds is elaborate this year (2015). For more information, please contact ours urbanism services.

In 2011, one person started inspecting septic installations on properties. The present program calls for such an inspection on all properties located within the boundaries of Municipality of Lac-Simon. The west side has been inspected and the east side will be inspected in 2012.

In order to protect the environment and people’s health, the municipal council, during an extraordinary session held on September20, 2007, voted in Bylaw number 395-2007 to counteract eutrophication of lakes and waterways and lower risks of proliferation of cyanobacteria, in accordance with the Municipal Powers Act LQ.2005, c.6. Under this Act, municipalities are granted powers to regulate in matters of the environment, sanitation, nuisances, safety and general well-being of the population.

There are many causes of eutrophication and proliferation of cyanobacteria, such as the following: overuse of fertilizers; use of detergents with phosphate; numerous defective installations for wastewater discharge and treatment; and grass mowing where part of phosphorous-rich residues are thrown in waters.

The bylaw requires, among other actions, that a shoreline protective strip be left fallow in order to prevent organic matter from reaching the water.

We there fore remind you that the bylaw prohibits the use of any fertilizer and any detergent with phosphate.

Any natural or legal person contravening this bylaw is liable to prosecution and to a fine up to $4,000.

Let’s protect our waterways together!

Banks and Littoral

Important Reminder: Adhere strictly to shore strip protection.

Is your lakeside bare? Let nature follow its course and vegetation will soon fill it. The best adapted indigenous species will grow there as long as they are kept secure from mower blades!

Talk to our Municipal Director of Building-Environment and Planning before doing any work. Prevention is the most efficient way to avoid damage to our bodies of water and costs of revitalizing banks.

Fuel Wood

DID YOU KNOW THAT moving fuel wood, even just a few kilometres, may help spread insects in our forests? It is difficult to imagine that something as simple as bringing fuel wood to a favourite campground or cabin can endanger and destroy thousands of trees!

Invasive insects are propagated this way, hidden underthe bark.

The emerald ash borer (invasive insect from the Orient) has killed millions of ash trees in the United States and Southern Canada, right up to Ottawa. The Gatineau region is presently under alert and it is forbidden to move fuel wood out of the area, because fuel wood is the most important propagation vector.

Then, what can be done? Buy fuel wood on location; inquire about where it comes from; leave on site anything that comes from a natural source.

Camp Fire

DID YOU KNOW THAT ashes from a camp fire that is too near the water, i.e. within the shore strip, produces significant quantities of nutrients such as phosphates, nitrates, potashes, as well as pollutants such as heavy metals iflake water covers the ashes or the ashes are washed down the lake?

These nutrients promote the fast growth of algae and aquatic vegetation.

That’s why camp fires are prohibited on the shore strip (where lake water can submerge the land). If ever make a camp fire near the lake, it is important that you shovel up the cold ashes and carry them to a more appropriate place.


Swimmer’s Itch

When in contact with water, it can happen that a parasite called cercaria (microscopic worm) gets under the skin and causes skin rash and itching. They are carried by infested aquatic birds. However, they are not a danger to human health.

Cercarias stick to your skin when bathing. As the skin dries, cercarias hide under the skin where they die. Red spots appear on the skin and swell like insect bites. Itching can last up to 10 days.

Recommendations to prevent the swimmer’s itch:



While bats are declining in number, mosquito populations are increasing.

Indeed, the bat population has decreased by nearly 70%.

When you know that a single bat can eat more than a thousand insects per night, it’s easy to imagine how much more comfortable garden life would be if your property had a shelter for a colony of bats.

Often maligned and misunderstood, bats are victim of the scarcity of their reproduction and hibernation sites.

Generally, bats hibernate in old mines or migrate south. They reproduce in attics, in tree holes and in artificial shelters built according to the plan below.

Installing a bat shelter:

The shelter must be in a spot where there is at least 8 hours of sunshine a day.

Therefore, if you want to save the bats and enjoy fewer mosquitoes, build a bat shelter. Above all, don’t scare them away from your home; they are your allies.


Like bats, swallows decrease significantly the mosquito population around your house.

The swallow population has decreased by 70%.

There are many reasons: use of pesticides; nest destruction by non-native birds, such as sparrows and starlings; migration; and nest built on plastic surface where it cannot stick and falls off.

However, one of the main causes is nest destruction by humans.

Too often, nests are destroyed on the pretense that droppings stain outside walls. There is a simple trick to avoid the mess: place a board 50 cm long and 15 cm wide about 1.2 m under the nest. This shelf will catch the droppings and prevent stains on the façade.

And what a pleasure to hear the swallows, to see their endless comings and goings, and above all, to have fewer mosquitoes!

Beaver Dam

Organisme de bassins versants des rivières Rouge, Petite-Nation et Saumon

The Organisme de bassins versants des rivières Rouge, Petite-Nation et Saumon (OBV RPNS) has started work to stabilize beaver dams that could cause damages.

There are two such sites in the Municipality of Lac-Simon.Drains and systems of flexible pipes and cages (‘cubes Morency) have been installed to lower permanently the water level.

Keeping the water at the right level is better than trapping the beavers. When you trap beavers, they are soon replaced by younger beavers that reproduce faster. If you protect the older beaver family already present on the site, reproduction slows and there are fewer animals felling trees. It’s a more efficient approach andmore respectful of nature. A great initiative from our OBV.
