Name
''Loch Coirib'' is a corruption of ''Loch Oirbsean''. According to placename lore, this refers to Oirbsen or Oirbsiu—another name for the
Tuatha Dé Danann figure
Manannán mac Lir—who is believed to have been a god of the sea. In Irish, the lough is also called ''An Choirib'' ("the Corrib").
Marine archaeology and charts
Surveys have been undertaken since 2007 by a local surveyor/cartographer to create up-to-date charts of Lough Corrib. These have uncovered a number of objects of historical significance, which have been investigated by the
Underwater Archaeology Unit of the
National Monuments Service. These include Bronze Age and Iron Age vessels (

Wildlife
The wildlife in Lough Corrib includes birds and hawks, otters, mink, stoat, frogs, and bats. Lough Corrib can be divided into two parts: a smaller shallower basin to the south and a larger deeper basin to the north. These two parts are connected by a narrow channel. In the southern and eastern parts of the lake, the lake bed is dominated by limestone bedrock covered by deposits of precipitated marl. The surrounding land is mostly pastoral farmland to the south and east and bog to the west and north. In addition to the lake basis, some areas of scientific interest adjoining the lake, e.g. woodland, callows grassland and
raised bog
Raised bogs, also called ombrotrophic bogs, are acidic, wet habitats that are poor in mineral salts and are home to flora and fauna that can cope with such extreme conditions. Raised bogs, unlike fens, are exclusively fed by precipitation (ombrot ...

Threats to ecology

In early 2007, large numbers of the protozoan parasite ''
Cryptosporidium'' were detected in water from the lake, leading to contamination of the public water supply in
Galway city and an outbreak of
cryptosporidiosis. Another unwelcome visitor is the invasive species ''
Lagarosiphon major'' (also known as 'curly-leaved waterweed' or 'South African pondweed') which is destroying fish habitat and the
zebra mussel.

Dick Roche, the Minister of the Environment, later announced allocation of additional funds to tackle the issue. Measures included upgrading existing water treatment and filtration systems, as well as the projected importing of water from nearby Luimnagh,

Joyce Country and the mountains of
Connemara. There are some beaches and woods with walks around the island. There is evidence of an early monastic settlement, and two churches -
Saint Patrick's and the 12th century church known as the "saints" church. St. Brendan of Clonfert is also said to have spent some time on an island in this lake after returning from his travels in Britain. There are several paths around the island, an old cemetery and remains of four or five cottages which housed the few inhabitants.
Another lake island is Caislean-na-Circe, between Maam and Doon. This section of Lough Corrib is free from islands except for the rock on which the ancient
Hen's Castle of the O'Connor's and the O'Flaherty's stands. The castle was home of the pirate Queen
