In 2015, large parts of Cumbria were left under water following the storm after the surrounding rivers overflowed, flooding thousands of homes and businesses.

Samples were taken from Bassenthwaite Lake, which saw severe flooding in 2005, 2009 and 2015.

Storm Desmond brought a record-breaking 24 hours of rainfall measured at :

341.4mm
Honister Pass
322.6mm
at Thirlmere

A challenge that faces flood hazard managers and the insurance industry is to accurately identify the extent of flood risks to develop sufficient protection.

Storm Desmond damage cost an estimated £1.6 billion according to the Environment Agency.
