Chalk Streams
Our rivers are arguably our most important natural features. Not only do they help make the British landscape so picturesque and vibrant, they’ve been crucial for the growth of our towns and cities, providing fresh water for drinking and farming, and for our business and transport over centuries.
Some of our most beautiful rivers are ‘chalk streams’. Their pure, clear, constant water from underground chalk aquifers and springs, flowing across flinty gravel beds, make them perfect sources of clean water – and ideal for lots of wild creatures to breed and thrive. We’re lucky because the majority of the world’s chalk streams are found in England.
