History of ABCA
The former Ausable River Conservation Authority was Ontario’s first conservation authority. It was created in 1946. The Bayfield River watershed and smaller streams were added in 1971.
Local municipalities and the Province of Ontario formed Ausable Bayfield Conservation Authority (ABCA) to prevent the loss of important local ecosystems, to protect life and property through flood management, and to build a healthier natural environment on a watershed scale.
