After more than 90 years trout and salmon in the River Ely in Wales England were able to spawn due to the water quality improvements. Unfortunately, last week so much raw sewage was dumped into the river that all of the mature and spawning fish were all killed. Construction worker Greg Davies , 31, of Tonyrefail said: "The outlet has been pumping litres and litres of stinking raw sewage straight into the Ely since Friday killing every single thing in it. It's wiped out every living thing in the river from fish to insect life which is a tragedy when you consider the river has only just cleaned up enough to attract trout and salmon par back here after 90 years. I counted over 560 fish suffocated to death in the poisoned water. We couldn't save any of them. We couldn't rouse anyone to tackle it until Sunday and then only because the Ely runs through the grounds of the Royal Glamorgan Hospital. It has taken six years to restore the river since the closure of the paper mill and the removal of the weirs and now this - it's an environmental and public health disaster for the river." Another example of a sad and disppointing opportunity lost.
