Video report by ITV News Anglia's Malcolm Robertson
A stretch of river in Suffolk that was immortalised by the painter John Constable has almost vanished after a weir jammed open, emptying millions of gallons of water.
A cut off section of the River Stour near Sudbury has been reduced to a trickle after a weir became blocked at Great Cornard.
It's left water levels plummeting by up to six feet in places.
The Environment Agency have rescued more than 10,000 fish that were showing signs of distress. They are hoping divers to remove the obstruction when it's safe to do so.
John Constable, who was born in Suffolk, used the Stour as backdrop to some of his best-known works - including "The Hay Wain" a painting of a cart and horses in a pool on the river.
