Belhavel Lough (Irish: Claonloch, meaning 'crooked lake')[3] is a freshwater lake in the northwest of Ireland. It is located in north County Leitrim near the village of Killarga.

Geography and hydrology

[edit]

Belhavel Lough is about 2 kilometres (1.2 mi) south of Killarga and 5 km (3.1 mi) north of Drumkeeran.[1] It covers an area of 1.01 km2 (0.4 sq mi).[2] The lake drains east into the Diffagher River, which eventually reaches Lough Allen.[1]

Ecology

[edit]

The water quality was reported to be satisfactory c. 2001 – c. 2003 with a mesotrophic rating,[4][n 1] but had a "poor" ecological status c. 2007 – c. 2009 indicating pollution,[6] though Zebra mussel infestation was not reported.[7] The ecology of Belhavel Lough, and other county waterways, is threatened by curly waterweed, zebra mussel, and freshwater clam invasive species.[8][9]
