Ducks Unlimited of Canada has been engaged in a 40-year effort to create an 8,000-ha provincial wildlife reserve along the Ottawa River that will serve local communities and the nearby metropolitan areas of Ottawa and Montreal. This project contributes to that effort by restoring 6.9 hectares of wetland within the organization’s Lanthier and Trépanier reserve so it can receive and process more runoff from adjacent agricultural lands. Wetlands of this type can filter sediment and nutrients before water enters the receiving waters of Lochabor Bay and the Ottawa River. Additionally, wetlands promote groundwater infiltration, helping to recharge important groundwater aquifers.
