The municipality of St-Hippolyte announces that it will take care of the emptying and inspection of all sanitary facilities on its territory, as requested by the APLA for more than eighteen months.

The APLA sends free of charge to all its members and to residents of Lake Bass, more than 570 “Our lakes below the surface” DVDs. This pro-active gesture for the environment is one of the most important awareness-raising measures by a lake association in Quebec.

In order to continue the success it has achieved in its fight against gulls, APLA is adopting the very latest in scaring technology: the successive detonation cannon or Scare Canon.


The monitoring committee of the sanitary installations of the APLA proposes to the municipality of St-Hippolyte the implementation of a new two-part regulation: the assumption by the municipality of the inspection and the emptying of the sanitary installations on its territory and systematic inspection by dye or smoke tests of sanitary facilities every 5 years.

The APLA is continuing its program of reforestation of the shores of the lake by selling and sponsoring plants to its members during the annual environmental day organized jointly with the municipality.

The APLA is submitting a draft code of ethics to the municipality with the aim of constituting the first code of ethics for users of Lac de l’Achigan.


The APLA submits to the municipality a detailed working document aimed at better control of access and movement of boats on Lac de l’Achigan. The following points are notably put forward by APLA:

  1. Access to Lac de l’Achigan limited to residents of St-Hippolyte only
  2. More rigorous application of the sticker system for boats on the lake
  3. Increase in the frequency and efficiency of nautical patrols by the Inter-municipal Police Authority
  4. Improved control at the municipal jetty
  5. Problems related to parking and speed in the curve of the municipal beach
  6. Boat washing to minimize the introduction of invasive species into the lake

Following fundraising from its members, the APLA acquires and installs four Imites-Rapaces devices with the aim of reducing the number of gulls that harbor at Lac de l’Achigan. The droppings of these birds, which can number around 5,000 per evening during certain times of August, constitute a significant supply of phosphorus that APLA wants to combat.


Second municipal by-law to limit the speed of boats and personal watercraft to 10 km / h on the first 75 meters of the banks.


The APLA is organizing a first nautical patrol on the lake, an initiative which has since been assumed by the Municipality.


Dossier of Domaine Achigan. A private club in the 1970s, Domaine Achigan was sold in 1978 and became a marina and a windsurfing club with a bar, terrace, access to the public beach, use of personal watercraft, etc. The municipal beach becomes the “bay of horrors” a “real cancer” for the lake. The noise is excessive and accidents are numerous. To solve the problem, the developer proposes the construction of condos. The people of the neighborhood, who still remember the Pointe à Savaria, end up accepting this idea in the face of the City Council’s inaction. It was the first time in 25 years that people agreed to have the zoning by-law changed. City Council proposes to change the zoning to allow the construction of condos despite opposition from APLA.


Auberge des Cèdres is asking the Municipality to extend its use and increase the number of rooms. The APLA was consulted the following year and opposed any exceptions to the town planning regulations.


APLA asks the Municipality to analyze the water in the lake every year, which will help identify problematic areas with regard to sanitation facilities.

Strongly reversed file from Pointe à Savaria, facing Camp Bruchési. The Municipality is consulting the APLA about the construction of 16 condo units on the land of the old marina which operated a micro-flight school (seaplanes) and a gas station. APLA opposes this residential development but must accept a compromise: the developer retains an acquired right to three houses.


The Municipality proposes to modify the zoning by-law in order to allow tourist and residential development at Camp Bruchési. Strong opposition from APLA.

The provincial Department of Hunting and Fishing regulates ice fishing on Quebec lakes.


For ecological reasons, APLA opposes the opening of the lake for ice fishing.


Presentation of a brief when the MRC submits its development plan. As the municipality of Saint-Hippolyte is considered a tourist region of the MRC, the APLA wanted to ensure that this plan would not affect Lac de l’Achigan with regard to the development of the Bruchési and Weredale camps, the only two green areas not yet developed and considered as “the lungs of Lake Achigan”.


Pressure to regulate motorized boats, access to the municipal beach for boats, and to reserve the municipal beach for residents of Saint-Hippolyte only. Strong opposition from the Chamber of Commerce and protest against APLA.

Adoption of a by-law on boat speed, engine power and boat size.

The Municipality controls access to the lake.


APLA participates in the FAPEL lakes program, distributes more than 35,000 plants to regenerate the banks and proposes a regulation limiting the deforestation of the banks.


Claims to control the pattern of development around the lake, sanitation facilities and the use of motorized boats.


The League of Owners of Lake Achigan was created in August 1964. It has two objectives: to improve the quality of the lake’s water and to form a pressure group to defend its interests within the Saint-Hippolyte municipal council. The League changed its name in July 1980 to become the Association of Owners of Lac de l’Achigan (APLA).
