An ex colleague of mine compiled these estimates of the flood volumes around the county during storm Desmond last December.

Hydrograph from Seaton mill.

I asked about a comparsion to 2009:

"Peak was around 408 cumecs which compares with about 300 in 2005 and 700 in 2009". That tallies well with my observations, 2015 was bad here, but no way as bad as the 2009 event.

interesting because on my part of the Derwent, between Ouse bridge and Isel bridge it was notably worse than 2009. the river was about 6 inches higher and the damage was more severe.

Presumably it shows how different the Derwent becomes once it meets the Cocker in Cockermouth, and it must be thanks to the Cocker not being as bad that had the knock on effect downstream towards Workington.

Hue volumes of water !!

Any ideas on how it compares with the last flood ?

Thanks for adding the data, much appreciated


EDIT REQUEST


Can your colleague do a similar series of charts for an average day, so we can compare an extreme with a norm ?

Also I am very interested in the River Caldew if he has any data for that River ( My son is a Geography teacher at local school and they look at the Caldew in detail, so any data would be very useful, many thanks )

Think you can get the data from, the EA website. I shall look sometime.

http://nrfa.ceh.ac.uk/data/station/meanflow/75002

Camerton, mean flow 1960-2008 ~27 cumecs. Estimated 2009 (whilst station was being destroyed) ~720 +/- 60)

Lots of data on that site to browse through.
