Restoration of Lake Nick Outlet (Ongoing project)
The outlet of Lake Nick will undergo restoration work. The details of the project will be specified in the coming weeks.
Background
The outlet of Lake Nick, located at 40 Chemin Public and 3 Rue Bayview, is the point where water exits the lake and flows into a stream that passes through Larochelle Pond, crosses Chemin Public, and continues toward Fisher Pond.
Since the 1960s, this area has undergone several human interventions. A canal was initially dug to lower the lake level and create a beach, then later filled with natural backfill. This backfill now forms what is known as the Kaizer Dike, a 10-meter-long structure made of gravel, stones, and sand.
Current Conditions
Over the years, beaver activity and citizen interventions have altered the outlet’s structure and water dynamics. In 2023, at the request of members of the APLN, the Municipality commissioned two technical studies to assess the stability of the structure and the relevance of a restoration project.
Key findings include:
- The dike is generally stable, though signs of erosion are present.
- Some infiltration is occurring, but it does not compromise structural integrity.
- The control structure, although built informally, is considered relatively stable.
Options Under Consideration
Option 1: No Intervention
Leave the site as is. This would result in gradual erosion, requiring ongoing monitoring.
Option 2: Minimal Maintenance
Remove unstable or dead trees. This would reduce immediate risks but would not prevent long-term erosion.
Option 3: Rehabilitation
Stabilize the control structure and dike using rock armoring or vegetation. A stable overflow channel would be created. Materials suitable for manual handling would be prioritized due to limited site access.
Option 4: Full Reconstruction
Replace the current structure with a fixed hydraulic control system. This would require a robust access route for machinery and materials.
Conclusion
The site is environmentally sensitive. While erosion risks are considered minor, the Municipality continues to evaluate the best course of action to ensure safety, stability, and environmental protection.
