A river restoration scheme has been completed on the Afon Clydach near Llangadog to help migratory fish.

The project forms part of the river restoration work managed by Natural Resources Wales (NRW) under the Four Rivers for LIFE Project.

The Jerusalem Weir was a significant obstacle for salmon and other fish trying to reach upstream to spawn.

As removing the barrier was not an option due to the historical bridge's support, a Larinier fish pass was installed.

This pass improves the passage for salmon, trout, and other weaker swimming species by reducing flow velocities.

It also features a side slot with bristles for eels and lampreys.

Susie Kinghan, Four Rivers for LIFE project manager, said: "Free and unrestricted access between the river and the sea is essential for salmon and other fish to complete their life cycle.

"This scheme should significantly improve the movement of salmon further upstream and their access to important breeding areas.

"It will also benefit lamprey and eel."

The fish pass was developed by NRW's fisheries department in collaboration with Fishtek.

Dave Charlesworth, NRW's freshwater fisheries lead specialist, said: "Salmon populations in Wales are suffering the effects of climate change right now and it is essential that we identify and protect strongholds within river catchments where they continue to spawn successfully.

"We hope this scheme contributes to an increase in the numbers of salmon and other migratory fish species in this river over the coming years."

The work at Jerusalem Weir took two weeks to complete by specialist contractor Paul's Plant Hire.

The project was done with care to protect the historical environment, as Jerusalem Weir, the mill leat, and the bridge are all listed as Historic Environment Records.

Heneb, the trust for Welsh archaeology, was closely involved in the project to ensure no damage to the historical environment.

The Clydach is a tributary of the River Tywi Special Area of Conservation (SAC), which is protected for its variety of migratory fish.

The project was funded by the Four Rivers for LIFE Project which is in turn funded by EU LIFE.
