I think most of us like lakes - for their own beauty and for the wildlife that lives in and on them.
Unfortunately in my area there are few natural lakes - certainly no large ones: the Dark Peak is a plateau and the White Peak is limestone so the water disappears below ground (the biggest lakes in Derbyshire are probably underground).
So we have to make do with reservoirs - rivers dammed up to provide water for drinking and industry. Some of our are quite large and spectacular but some of the older ones are quite photogenic:
Unfortunately, ones, such as this, on the sandstone are acidic and have little in the way of plant or animal life in them - but quite pretty - and there are curlews on the surrounding moors ....
