Catfish Creek Source Protection Area

The Catfish Creek watershed includes Catfish Creek and its tributaries. They drain an area of about 490 square kilometres in Elgin and Oxford counties. It enters Lake Erie at Port Bruce.

Much of the land of the Catfish Creek watershed is used for agriculture. The City of St. Thomas and the Town of Aylmer are the major urban areas, with other settlements at Springfield and Port Bruce.

The watershed has one municipal drinking water system in the village of Brownsville in the Township of South-West Oxford. The system has two wells that provide water to about 500 people. The Elgin Area Primary Water Supply System also provides municipal water to a number of communities in the watershed, including the Town of Aylmer and Port Bruce and Copenhagen in the Township of Malahide.
