Thirlmere is a reservoir, created in 1894 to  provide Manchester with water, but now also supplying Keswick and environs. Located beneath Helvellyn, two small lakes and a hamlet were drowned by the building of a large dam at the northern end of the valley. Forestry clearance in the area has transformed the landscape in recent years.
