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
