The Richibucto River flows through southeastern New Brunswick, draining a watershed of approximately 1,088.5 square kilometres before emptying into Richibucto Bay and ultimately the Northumberland Strait. It is a tidal river system with a wide, navigable lower section that transitions into a productive estuary environment. The river is recognized as one of New Brunswick's productive striped bass destinations, offering notably less fishing pressure than the more famous Miramichi River to the north. The lower river and harbour area are deep and wide enough to accommodate both small and larger vessels, making it accessible to boaters as well as shore anglers. The surrounding watershed is set within a coastal plain and includes the Richibucto River, the St. Charles River, and several other tributaries draining into the Northwest Branch, with the system extending outward to the barrier beaches of the Richibucto South Dune and Richibucto North Dune.
