The two year restoration project at Carlisle Conservation Area is now complete, the roots of this plan however date back much further. Conservation Halton notes that it was back in the 1960's when this watercourse was originally deepened and widened for recreational use. Then, in 1992, a watershed study of Bronte Creek was completed which showed that it would be necessary to remediate those alterations, that work began in the early 2020's.
