Hundreds of dead fish were found floating in shallow water this week.
The ECHO returned to the Sankey Canal at Spike Island on Tuesday morning and to the spot where the piles of dead fish had collected next to a short wooden dam. On the other side of the barrier was a previous section of canal that was now a muddy plane and nearly dried out.
Bags of dead fish removed by volunteers had also been deposited at the water's edge close to the Spike Island boat hut, attracting the attention of flies. These fish included much larger specimens, with one visitor estimating their individual weights at around up to 30 pounds - around the same weight as a medium sized dog - and their aged of up to around 30 years.
