Plans are underway to ensure water levels in the canal can be maintained following a recent series of heat waves.
Sections of the Monmouthshire and Brecon Canal have run dry this summer due to a lack of rainfall and reduced water levels flowing into the canal from its two feeders in Cwmbran.
A stretch of the canal owned by the Canal & River Trust, north from Bridge 47 in Sebastopol, has been closed to boats due to a bed valve failure which has caused a small breach within the canal bed.
Stop planks, which create temporary dams, have been installed as a temporary measure while engineers assess the situation.
It's hoped recently completed work to reduce leaks along the cascades near Llandowlais Street, in Cwmbran, and planned dredging and weeding work in the autumn will help improve water flow and quality when rain and water levels increase.
Chris Wyatt, the council's Canal Co-ordinator, said: "Seeing parts of the canal run dry is distressing for everyone, however, this has been an exceptionally dry summer.
"Our priority is to ensure that when we get more rain and water flowing into the canal, we are able to maintain the water level and flow to support wildlife and make sure the canal is an attractive place to visit.
"In the meantime, we ask that people do not remove any temporary dams they may see along the canal. These are positioned at intervals along the canal to manage water and tampering with them can affect water retention".
In June, council teams and volunteer cleared an overgrown section of canal near Two Locks following the discovery of dead fish in the area.
It is believed the fish died due to a drop in oxygen levels caused by a combination of the overgrown plants, a reduction in water levels and the warm weather.
Following approval by Natural Resources Wales, volunteers from the Bridge 46 to Five Locks Canal Group, the Monmouthshire, Brecon & Abergavenny Canals Trust and Cwmbran Angling Association, worked alongside canal co-ordinator Chris Wyatt and councillors, to clear a channel through the vegetation as a temporary measure until the large-scale works are undertaken in the autumn.
