Emy Lough is a lake of approximately 130 acres located just outside the village of Emyvale in north County Monaghan, with a shoreline of roughly 2.25 miles. Its coordinates place it at 54°20′N, 6°56′W in the Ulster region of Ireland.

Paddlers considering a visit should be aware of significant restrictions on the water. Emy Lough serves as a drinking water source for local communities, and outboard engines are not permitted on the lake. More critically, private boats of any kind are not allowed on the water. Boating access is limited exclusively to club-operated vessels managed by the Emy and District Angling Club, which administers the lake as a state fishery. There is no provision for private canoes, kayaks, or other paddle craft to be launched. Anyone wishing to use a boat on the lake must contact the club directly through Paul Gormley at 00 353 47 87573 or 00 353 87 6128259 to confirm what, if any, arrangements might be possible.

The lake does have a well-developed shoreside infrastructure. A 4km looped lakeside nature walk circuits the water, providing good access around the full perimeter. Swimming and picnic facilities are also present, along with a children's play area and free car parking. The surrounding landscape is characteristic of north Monaghan's drumlin country, with the Mountain Water River feeding the lough from the Slieve Beagh Mountains to the west.

Given the prohibition on private boats, paddlers should contact the Emy and District Angling Club before planning any trip involving watercraft on this lake.
