Resources |  Bluffs & Gullies

FUN facts

Approximately 200 gullies have formed along the southeastern shores.


Bluffs on the southeastern shores are made of 86% silt and clay, 14% sand, gravel, and cobbles.

~72% of the sediment feeding beaches on the southeastern shores comes from gully erosion.

PUBLICATIONs & Fact sheets

A steep vertical exposure comprised of clay, sand, shale, bedrock, limestone, or any combination of these. These areas are prone to erosion due to their direct interaction with changing lake levels


Bluffs and gullies are a beautiful and important part of our ecosystems but they can cause concern for cottagers and municipalities. Our Coastal Science and Stewardship advisors have the expertise and considerable experience providing help and advice. Additionally, we have produced a number of bluff management guides and materials.

Bluffs and gullies feed 72% of the sediment to beaches down-drift and offer spectacular views of Lake Huron to residents and visitors. Volatile and ever-changing, these ecosystems are important features on the southeastern shores.



What will the Lake Huron bluff shoreline look like in 100 years? Although stewardship may help to slow down erosion, it is important to recognize that bluff erosion is inevitable. This webinar presented by Stephen Jackson, the Watershed Resources Engineer at Maitland Valley Conservation Authority will help municipalities and landowners understand the risks associated with development along the bluffs and provide an overview of bluff stewardship techniques.
