Emergency crews are racing to save a damaged reservoir, as "terrified" residents fear their Derbyshire town could be flooded.
Water is being pumped out of the 300-million-gallon Toddbrook Reservoir and an RAF helicopter is dropping 400 tonnes of aggregate around it.
Part of the dam wall collapsed on Thursday afternoon.
About 1,500 people evacuated Whaley Bridge amid warnings they were in "mortal danger".
A worrying situation for those people who were evacuated yesterday from that Derbyshire town.
Looks like the RAF chinook are trying their best to save the damn, I certainly wouldn't fancy those pilot's jobs!
Can the dam be saved?
