Belhavel Lough
Belhavel Lough (Irish: Claonloch, meaning 'crooked lake') is a freshwater lake in the northwest of Ireland. It is located in north County Leitrim near the village of Killarga.
Geography and hydrology
Belhavel Lough is about 2 kilometres (1.2 mi) south of Killarga and 5 km (3.1 mi) north of Drumkeeran. It covers an area of 1.01 km (0.4 sq mi). The lake drains east into the Diffagher River, which eventually reaches Lough Allen.
Ecology
The water quality was reported to be satisfactory c. 2001 – c. 2003 with a mesotrophic rating, but had a "poor" ecological status c. 2007 – c. 2009 indicating pollution, though Zebra mussel infestation was not reported. The ecology of Belhavel Lough, and other county waterways, is threatened by curly waterweed, zebra mussel, and freshwater clam invasive species.
