Ullswater is the second largest lake in the English Lake District, being about nine miles (14.5 km) long and 0.75 miles (1.2 km) wide, with a maximum depth a little more than 60 metres (197 ft). Ullswater’s visitor centre website describes it as the most beautiful of England’s lakes;[2] it has been compared to Lake Lucerne in Switzerland as a tourist destination. It is a typical Lake District narrow “ribbon lake” formed after the last ice age by a glacier scooping out the valley floor, which filled with meltwater. Ullswater was formed by three separate glaciers. The surrounding mountains give it the shape of an extenuated ‘Z’ with three segments or reaches winding through surrounding hills. For much of its length, Ullswater formed the border between the historic counties of Cumberland and Westmorland.
