The Bot/Kleinmond Estuary is a relatively shallow coastal lake and estuarine system situated in the Overberg District of the Western Cape. It is a vital ecosystem, designated as a Ramsar Wetland of International Importance, and serves as a crucial nursery habitat for marine fish species. The system is characterized by its shallow nature, with a mean depth of approximately 1.5 meters above mean sea level, and its mouth alternates between being open to the sea and closed by a sand berm, a typical feature of Temporarily Open/Closed Estuaries (TOCEs) along this coastline.
