After Hurricane Hazel in 1954 a system of dams were built on the watersheds throughout Southern Ontario. The Nottawasaga Valley Conservation Authority maintains the dams and levees throughout the Nottawasaga River watershed. The dam at the New Lowell Conservation Area (aka the New Lowell Pond), controls flooding on Coates Creek, a tributary of the Nottawasaga.
