As the lead agency appointed to manage the Mississippi Valley watershed, MVCA aims to balance your needs with the needs of the environment to protect the things you love like safe drinking water, local ecosystems, your property, and a healthy economic framework based on recreational tourism.

Located in eastern Ontario, Mississippi Valley Conservation Authority’s jurisdiction encompasses three different watersheds: Mississippi River (3,750 sq. km.), Carp River (700 sq. km.) and the Ottawa River.
