Twelve Mile Creek

Twelve Mile Creek is the last remaining spring-fed cold water stream in the Niagara Peninsula with a known native population of Brook Trout.


Human activities have altered the physical, chemical, and biological characteristics of Twelve Mile Creek.

As a result, the quality of the water has degraded, causing the population of native Brook Trout to dwindle. Today, we have a better understanding of the importance of watersheds and the impacts that people can have on them. Restoring watersheds takes time, commitment and community involvement, but the benefits of a healthy aquatic environment are easily worth the effort.

True restoration can only be accomplished by working at the watershed level.

Our project focuses on restoring the headwaters, located across the Town of Pelham and City of Thorold in the Niagara Region

The first objective of our restoration plan is to prevent further degradation of habitat. 

Healthy watersheds, clean water, and healthy aquatic habitats should be of interest to all of us. Healthy watersheds mean increased biodiversity, healthy water quality, and decreased flooding and erosion risks.

To achieve long-term success, we address the causes and not just the symptoms of ecological disturbance.


Stream Rehabilitation is the conservation and rehabilitation of watersheds and streams by trained and knowledgeable restoration experts.

The Niagara Chapter utilizes ecological restoration techniques to rehabilitate fish habitat and reduce erosion and sedimentation in the system. Such restoration techniques include riparian planting, reforestation, live cribwalls, LUNKERS cross vanes,
deflector vanes, etc.

Examples of the methods our project uses to improve the conditions of a stream include:

The stabilization of stream banks and shorelines with natural materials such as vegetation, woody debris, and stones/boulders.

The addition or removal of structures to allow and enhance fish passage (removing woody debris, culvert replacement, etc.)

The reestablishment of riparian buffer and tree cover through the planting of native vegetation 

The improvement of water quality characteristics and indicators (e.g. dissolved oxygen, pH, benthics, etc.) through the reduction of sediment, thermal pollution, run-off etc. 


Resources For Landowners

Healthy Twelve Mile Creek aims to educate and encourage landowners to become ‘stewards’ of Twelve Mile Creek.

Brook Trout

Brook Trout are an indicator species for healthy waterways. Once plentiful in Twelve Mile Creek, Brook Trout numbers are dwindling.

Healthy Twelve Mile Creek is a project of the Niagara Chapter of Trout Unlimited Canada with the support from multiple generous funders to improve the Twelve Mile Creek watershed.
