Why is it called Derwent Water?
First thing you can do, while wiggling your toes in the water, is point out how clear the lake is. Derwent Water gets its name from a Celtic word for ‘Clear Water’ or alternatively from an Old English term meaning a region abundant with oak trees. So I recommend combining the two and informing everyone how the name was derived from a combination of Celtic and Old English meaning ‘Clear water surrounded by oak trees’ point out the clarity of the water and the density of oaks around the perimeter. Very impressive.
