A RIVER RUNS THROUGH IT - STRAIGHTENING THE RIVER CALDER

The river Calder is an important Cumbrian habitat for river wildlife. Creatures that make their way to the Irish Sea from the river Calder and Ehen include brown trout which become sea trout and eels which make an incredible journey to the Sargasso Sea near Bermuda. Their journey takes them through ancient landscapes, the river meanders in serpentine loops all the way until it reaches Sellafield. What a shock the animals have, here the river Calder has been straightened so that radioactive discharges and run off released into the river can pass through the 6 mile nuclear plant as quickly as possible.

"the Calder was originally a meandering river through the middle of the site"
