The Upper Kennebec Estuary

Six rivers – the Kennebec, Androscoggin, Cathance, Abagadasset, Muddy and Eastern – converge to form Merrymeeting Bay in the upper Kennebec estuary. This inland body of fresh and brackish tidal waters drains nearly forty percent of Maine, creating shallow, nutrient rich waters, expanses of wild rice, and more than 4,500 acres of prime waterfowl habitat.
