Black Ash Creek runs from the top of the Niagara Escarpment and through the Town of Collingwood before reaching Georgian Bay. Historically, the creek was home to native brook trout. Today, while the creek supports a healthy rainbow trout population, only a few wild brook trout remain in the upstream reaches. Trout need cold water to thrive. Removing the Petun dam and the stagnant head pond it supports will lower water temperatures in the creek. This will enhance habitat for rainbow trout and provide an opportunity to reintroduce native brook trout. It will also improve water quality overall. NVCA is partnering with the Town of The Blue Mountains, Bruce Power and other groups on this project, which will enhance and protect this important fishery.
