The Inny River (an Eíthne) is a tributary of the Shannon. It flows about 2 miles south-east of Legan and borders County Westmeath. The Inny flows through Lough Sheelin, Lake Derravarragh and into Lough Ree in the Shannon near Ballymahon.
A six mile section of the river is controlled by the local Legan Inny
Anglers Development Association (I.A.D.A.). The I.A.D.A. fishing club was
set up about twenty years ago. Its main aim is to promote fishing
and to improve fishing facilities in the Legan area. The I.A.D.A. has a membership of about 30.
Pike fishing competitions are held every month. The All Ireland pike pairs competition is also organised and ran by the organisation, and takes place in mid-April.
The most important feature of the club is the fact that no fish are killed,
as all competitions are on a catch / weigh / release basis. Fishing is a
becoming a very popular sport.
