NRW Reducing Flood Risk in Dolgellau

Natural Resources Wales is clearing approximately 1,500 tonnes of gravel from underneath the Bont Fawr in Dolgellau to stop it blocking the arches in the bridge.

During heavy rain, this could cause the water to back up, threatening the town with flooding. The work is in addition to the almost-completed £5.6 million scheme to build new flood defenses on the Wnion and Aran rivers in the town.

NRW workers spent three days last week clearing Himalayan Balsam from near the bridge. This invasive plant outcompetes native species and erodes river banks, increasing the risk of flooding.

Now they can go ahead and clear the gravel which is reducing the flow of water underneath four of the bridge’s seven arches.

The work is expected to take about a week to complete.
