Why Shorelines Matter

Healthy lakes begin at the shoreline. This narrow strip of land - where water meets land - is one of the most ecologically important areas in any watershed. How it is managed directly affects water quality, wildlife habitat, and the long-term resilience of the lake itself. Shoreline and lake stewardship is the shared responsibility of every waterfront property owner. As development pressure increases across Ontario’s lakes, adopting stewardship practices is essential to preserving the natural systems that sustain them. 

Shorelines act as a critical transition zone between terrestrial and aquatic ecosystems. When healthy and naturalized, they perform a range of essential functions:

  • Filter runoff by trapping sediment, nutrients, and pollutants before they reach the water
  • Stabilize soil and prevent erosion through deep-rooted vegetation
  • Provide habitat for fish, birds, amphibians, and pollinators
  • Regulate water quality by reducing excess nutrients that lead to algae growth
Without these natural buffers, rainwater flows quickly over hardened or cleared land, carrying contaminants like phosphorus and nitrogen into lakes - degrading water quality and accelerating aquatic weed and algae growth.

The Problem With "Hardened" Shorelines
Many traditional waterfront practices - such as retaining walls, manicured lawns to the water’s edge, and large paved areas - create what are known as hardened shorelines. While these may appear tidy or protective in the short term, they often cause long-term damage:

  • Increase erosion by reflecting wave energy rather than absorbing it
  • Eliminate critical shallow-water habitat
  • Reduce natural shoreline flexibility during changing water levels
  • Contribute to poorer water quality and sediment disturbance
In contrast, natural shorelines dissipate wave energy and adapt over time, making them far more resilient.

The Benefits of "Soft" (i.e. Natural) Shorelines
A "soft" or natural shoreline uses native vegetation, woody debris, and natural materials to stabilize the land while supporting ecological function. These shorelines:

  • Reduce flooding and erosion by absorbing excess water during heavy rain
  • Improve water quality by filtering runoff
  • Enhance biodiversity by creating interconnected habitat
  • Sequester carbon and cycle nutrients, supporting overall ecosystem health
  • Reduce the impact of wave action during storms
  • Adjust more naturally to changing water levels
Natural vegetation - trees, shrubs, grasses, and aquatic plants - acts as a living buffer, binding soil and managing water movement in ways that engineered structures cannot replicate. Rigid structures often fail under extreme weather events, fluctuating water levels, and shoreline erosion, requiring costly repairs and contributing to further environmental degradation.
What Stewardship Looks Like in Practice
Effective shoreline stewardship is not about leaving your property unmanaged, it’s about working with natural systems rather than against them. Key practices include:

1. Maintain or Restore Natural Vegetation
Keeping a buffer of native plants along the shoreline is one of the most important actions a property owner can take. These buffers slow runoff, filter pollutants, and stabilize soil.
2. Limit Lawn and Impervious Surfaces
Lawns and hard surfaces like driveways increase runoff and reduce infiltration. Reducing these areas helps protect the lake.
3. Manage Stormwater
Practices like rain gardens and directing runoff into vegetated areas allow water to soak into the ground rather than flow directly into the lake.
4. Protect Aquatic Plants
Aquatic vegetation is often misunderstood but plays a crucial role in maintaining water quality and providing habitat.
5. Prevent Invasive Species
Cleaning boats and equipment and avoiding the introduction of non-native plants helps protect lake ecosystems.
6. Maintain Septic Systems
Properly functioning septic systems prevent nutrient pollution and contamination of groundwater and surface water. These actions reflect a broader principle: What happens on land directly affects the lake. 
Stewardship is a shared responsibility
Lake health is cumulative - every individual shoreline contributes to the condition of the entire waterbody. Even small actions, when taken collectively, have a significant impact. Stewardship is not just about environmental protection - it also enhances property value, reduces maintenance costs, and preserves the recreational and aesthetic qualities that draw people to lakes in the first place.
