Magaguadavic River flows out of Magaguadavic Lake and runs to the Passamaquody Bay forming the Magaguadavic Watershed. It and its branches were used to power several mills in the Harvey RC area. The Harvey Lakes are also part of this watershed whereas the other lakes are part of the Wolastoq/Saint John River Basin.
