Barrier Removals on the Afon Tywi

Surveys of Tywi tributaries have shown barriers to fish migration caused by fallen timber, often sealed by waste plastic (typically silage wrap). The Carmarthenshire Fisherman’s Federation removed these from the Myddyfi, Mynys and Crychiau. Further, work was completed after the River Restoration Project surveys were completed in 2021.

This type of work is ideally carried out during low flows and the plastic removed while the timber is cut up. The result is the free movement of fish.

Timber debris enveloped in wrap was stopping all migration

The key timber was left in place, but the rest of the debris was cleared and the natural flow was restored. The good news was that the pools were crammed with fry and even some small eels were spotted.
