Littoral Zone: Extends from the water’s edge to the area in the lake where sunlight no longer penetratesand is home to organisms such as algae and aquatic plants, as well as aquatic organisms (fish,amphibians, and waterfowl)3.3: Shoreline HealthCommon Signs of a Healthy Shoreline• Lots of native vegetation• Different levels of vegetation• Dead snags and stones• Birds, fish and other wildlife are presentCommon signs of an Unhealthy Shoreline• Area is stripped of all or most vegetation• Lawn extends right to the water’s edge• Natural shoreline has been replaced by an opposing structure such as a break-wall or gabionbaskets• Erosion may be apparent (water may become “muddy” during rain)• Algal blooms and excessive weed growth are prominentCommon Human Induced Erosion• Removal of shoreline Vegetation• Runoff• Boat Wake- Unnaturally large waves created by boats eat away at the shoreline soil bit by bit. InOntario, the law is; boats must slow down to 10km/hr when within 30ft. From shore.• Construction- Construction activity often exposes soil which is very susceptible to erosion21
