Lough Ennell is a lake near the town of Mullingar, County Westmeath, Ireland.
The lake is part of the Lough Ennell Special Protection Area.
It is 6.5 km (4.0 mi) long by 2 km (1.2 mi) wide, with an area of about 12 km2 (4.6 sq mi).
Lough Ennell has a large area of shallow water with nearly two-thirds of its area being less than 25 feet (8 m) and almost half of it being under 10 ft (3.0 m) deep.
The main river flowing into Lough Ennell is the River Brosna, which enters on the Mullingar side of the lake and exits on the opposite side at Lilliput.
Brown trout and pike are the main catches. The lake produced Irelands largest ever lake brown trout at 26 lbs (11.8 kg).
In recent times it appears that stocks of both game and coarse fish in the lake have been declining.
