We need your help to reach our goal of raising $10,000 so we can move forward on the weir removal project on Hanlon Creek this September.

We're excited about this Project

The Hanlon Creek Weir Removal Project is an excellent opportunity to make a significant improvement to a coldwater Brook Trout stream and habitat within the Guelph community, and we could sure use your help!

A little bit of context

Hanlon Creek is a coldwater Brook Trout stream, with its headwaters rising within the City of Guelph, Ontario.  The Hanlon Creek weir was built in 1972  to measure stream flow.  The Grand River Fisheries Management Plan identified issues and management strategies to improve cold water tributaries of the Speed River Basin, which includes the Hanlon Creek.

So what's the problem?

Hanlon Creek weir is a barrier to fish passage, it interferes with sediment transport and causes upstream ponding with increased surface area that warms in the sun.  This warming of the creek has negative impacts on water quality and the Brook Trout that require clear, cool waters below 24°C. 

Alex Meeker, a biologist with Trout Unlimited Canada (TUC), says "brook trout have been considered the “canary in the coal mine” for a while.  Brook trout are a finicky species that only flourish under specific conditions, and they’re a good indicator of the effects of climate change. Their population has been in steady decline since the 1980s", says Meeker.

Lowering the stream’s temperature should also improve the city's drinking water, as cooler streams are more resistant to bacterial growth.

So if we're helping to protect areas that are important to sustaining trout habitats, we're actually investing in the health of our own communities as well,” she said.

Here's what we're doing about it

By removing the centre portion of the weir the upstream water level will be lowered and the channel narrowed.  This will lower stream temperatures, improve water quality, help reinstate natural processes, allow sediment to move downstream, remove a barrier to fish passage and prime spawning areas, and open up an up an additional 3.6 km of Brook Trout habit within the watershed.

Simply speaking, this important modification will improve Hanlon Creek stream health for this coldwater Brook Trout fishery and, most importantly, it will improve the fishery's resiliency to climate change.

It is our intent to install a permanent sign adjacent to the project site to inform the large number of visitors that frequent Preservation Park and the Hanlon Creek Dog Park about the value of the aquatic resources and the work that was done to restore stream health and Brook Trout habitat.

The project is now at a critical last phase where funds are required to complete the actual removal of a large portion of the weir and rehabilitate this section of the stream.  If sufficient funds are raised we will carry out this work in September, and it will take approximately 2 to 3 days.

We have a short-turnaround and are hoping you can help fund this important project.
