PENHORN LAKE WILL GET A SOLAR POWERED AERATOR THIS SPRING.
Thanks to Crombie REIT for their generous support. Crombie believes in building high-quality, sustainable real estate that enhances local communities for the long term. Their strong support and commitment to investing in welcoming communities make projects like this possible.
Lake stewardship is an important brand in Dartmouth. Crombie’s team is made up of people with strong Dartmouth roots who share and care about our community brand.
We are leveraging the example of the aerator deployed in Oathill Lake. Several years of community based monitoring across eleven of Dartmouth’s Lakes confirmed aeration is a problem primarily in only Oathill Lake and Lake Penhorn, each being deep nine metre pocket lakes, four hectares in size.
Committed funding for the project is provided 75% from Crombie REIT and 25% from Halifax Regional Municipality.
All labour and support will be volunteer efforts. The aerator will be removed before winter freeze and installed each spring thaw. It is self-sustaining with a life expectancy of 30 years, with solar panels needing replacement every ten years. The aerator will remove the anoxic water levels which during August peak variance rises to 1.5 metres from below the surface. Anoxic condition supports blue green algae known as cyanobacteria, certain types being highly toxic to dogs and humans.
Recreational swimming and fishing at Penhorn will be strongly enhanced by this project. Ice skating will not be impeded. Phosphate loading in the lake may also be reversed. Local action improving our local neighbourhoods, that’s our Dartmouth brand.
