Extent & description
Nepean Bay lies between Point Marsden and Kangaroo Head on the north-east coast of Kangaroo Island facing into Investigator Strait. Nepean Bay itself includes the following coastal inlets from west to east - Bay of Shoals, Western Cove and Eastern Cove. Eastern Cove itself includes an inlet consisting of a channel known as American River and a lagoon system known as Pelican Lagoon.
Bay of Shoals
The Bay of Shoals is a body of water which is located immediately north of the settlement of Kingscote and whose mouth is located between Cape Rouge in the north and Beatrice Point in the south over a distance of about 5 kilometres (3.1 mi). The bay has a maximum charted depth of 2.7 metres (8 ft 10 in). Its mouth is bounded by a spit known as 'The Spit' which extends from Cape Rouge to within 0.5 nautical miles (0.93 km; 0.58 mi) of Beatrice Point, includes the islets of Busby and Beatrice and is reported as being exposed during local tides, i.e. ‘drying.’ Access for watercraft into the bay is via a natural channel at its southern end near Beatrice Point.
Western Cove is a body of water whose mouth is located between Beare Point in the west and Morrison Point in the east separated by a distance of about 8 nautical miles (15 km; 9.2 mi). The cove has a maximum depth of about 10 metres (33 ft) at its mouth. Its shoreline is described as (distances in nautical miles):
The S(outh) shore, between Morrison Point and a red cliffy point about 3 miles W, is high and rocky. A range of wooded hills along the S(outh) shore falls gradually to the W(est). Red cliffs extend about 1.5 miles W(est) from the red cliffy point, and from there to the head of the cove is a continuous sandy beach. The land at the head of the cove is low and swampy and continues so to Beare Point…
Eastern Cove is the body of water whose mouth is located between Morrison Point in the west and Kangaroo Head in the east separated by a distance of about 6 nautical miles (11 km; 6.9 mi). The cove has a maximum depth of 14 metres (46 ft) at its mouth. Its shoreline is described as (distances in nautical miles):
The shore of Eastern Cove, between Kangaroo Head and American Beach, 2.5 miles S(outh), is rugged and rocky. Between the SW end of American Beach and Rocky Point, it consists of alternate beaches and low, rocky points. A sandy beach forms the S(outh) shore between Rocky Point and Strawbridge Point, 2.75 miles WNW. The S(outh) side of the cove is low with wooded hills at the back.
Eastern Cove includes Ballast Head Harbor on the western side near Ballast Head.
Matthew Flinders named Nepean Bay after Sir Evan Nepean, First Secretary to the Admiralty, on 21 March 1802.
