Net Count


Date Counted: 15th June 2022

The River Finn is one of the major salmon rivers in the Foyle catchment. The counter is situated at Killygordon and has been in operation since December 2000.

The Finn site has a 4-channel crump weir spanning the breadth of the river at this location. Each channel is built to a different level with the two central channels set at a lower level. The reason for the lower level channels is to enable all migratory species that use this river to get over the weir at lower water levels.
