The Grand River Conservation Authority (GRCA) is currently seeking feedback on proposed changes to the GRCA’s regulatory floodplain mapping under Ontario Regulation 41/24 for the Lower Conestogo River, between the Conestogo Dam near Glen Allan to where it meets the Grand River near the Village of Conestogo.  The proposed changes are the result of updated engineered modelling and topographic base mapping.  

Those interested can review the proposed mapping on the GRCA website and submit feedback until October 24, 2025, via the link below or by mail.   Learn more at https://www.grandriver.ca/lowerconestogoregmappingupdate.ca/
