[6] The upper reaches of the Reelin and the Finn are fast downstream to Ballybofey and can give excellent fishing.
In all there is more than 25 miles (40 km) of salmon fishing on the river from Flushtown right up to Bellanmore Bridge and part of the Reelan too.
There is good sea trout fishing at Liscooley and Killygordan and from Ballybofey to Bellanamore Bridge.
The Finn and its tributary the Reelan are probably the most prolific salmon and grilse rivers in Donegal and indeed throughout the Foyle catchment.
[4] Fish species such as roach, perch, eels and brown trout are caught in the Finn system.
