Roaringwater Bay

Roaringwater Bay, or Lough Trasnagh, is a bay in County Cork in south-western Ireland.

History

Until the late Middle Ages, large parts of Roaringwater Bay were under the control of chieftains, in particular O'Mahonys, O'Driscolls and McCarthys who built several castles in the area to control the fisheries and water access in general.

Geography

There are no officially defined boundaries of Roaringwater Bay. While Ordnance Survey Ireland maps place the name within the smaller inlet east of the Horse Island, the National Parks And Wildlife Service defined the Roaringwater Bay and Islands Special Area of Conservation as reaching as far west as Toormore Bay, and encompassing Cape Clear, Sherkin and Long Island. In any case the natural boundaries are the south-eastern shore of the Mizen Peninsula in the north, Baltimore Harbour in the south, and the wider, open Long Island Bay on the west.
The bay contains many islands, including what is known as Carbery's Hundred Isles. This group of islands spread between Roaringwater Bay and Long Island Bay, with the three largest being Cape Clear Island, Sherkin Island and Heir Island. Some of the islands in the bay, including Castle Island and Horse Island, are privately owned.
The bedrock of the area is composed of old red sandstone reefs, and most of the islands and coastal areas are relatively flat, only raising towards the south and culminating at 160m on Cape Clear.
The largest towns and villages around Roaringwater Bay include Schull, Ballydehob and Baltimore.

Wildlife and aquaculture

Roaringwater Bay is a Special Area of Conservation due to the presence of large shallow inlets, reefs, vegetated cliffs, dry heath, sea caves, as well as protected species including harbour porpoise, otter and grey seal. The National Parks and Wildlife Service has described Roaringwater Bay as "one of the most important sites in Ireland" for harbour porpoise and a "nationally
important" site for black guillemot.
Both historically and in the present day, the bay area has been used for cultivating aquaculture. Since before the Great Famine, some local fishermen specialised in lobster fishing. Distinct methods of fishing — using Cornish lobster pots and towelsail yawls — were developed, and fishing excursions from the Roaringwater Bay reached as far as Dursey Head in the north and Ardmore in the east. In 1892, 40 lobster boats operated in the area, with over three-quarters of them on Heir Island.
As of the year 2000, Roaringwater bay was producing over 800 tons of mussels and almost 200 tons of pacific oyster, with 2.4% of the bay area used for aquaculture, and over 30 people employed in the industry. Roaringwater Bay is one of the bays and harbours covered by the Co-Ordinated Local Aquaculture Management System run by Bord Iascaigh Mhara. Inclusion of the Roaringwater Bay in the CLAMS initiative was promoted by the actor Jeremy Irons whose Kilcoe Castle is situated on the bay's shore.

Maritime accidents

On 10 November 1847, the Stephen Whitney sank at West Calf Island in Roaringwater Bay. 92 people of the 110 on board the ship were drowned.
On 13 December 1904, a towelsail yawl overturned, with two of the five-men crew losing their lives.
In 1918, the Thomas Joseph ship sank at the Catalogue Islands, killing six.
