Geography and hydrology

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

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]

Notes
