Burnmoor Tarn, on Eskdale Fell in Cumbria, England, is the largest entirely natural tarns in the Lake District. Its waters flow into Whillan Beck at the tarn's north-eastern corner, which immediately turns south and flows into Eskdale, joining the Esk at Beckfoot.[1] Burnmoor Lodge, a former fishing lodge, stands by the southern shore and a mediaeval corpse road runs past the eastern shore where it fords the beck.[2] [3] Eskdale Moor or Boat How lies to the south of the tarn.
The tarn is one of the sites in DEFRA's UK Upland Waters Monitoring Network.[2] It occupies and lies at an altitude of in a moraine hollow on the uplands between Wastwater and Eskdale. The lake has two distinct basins close to the south-eastern shore and a maximum depth of . There are four main inflow streams to the north and north-west. The outflow at the eastern end joins the Hardrigg Beck which drains the slopes of Scafell and, in times of especially high flow, is partly diverted into the lake across a braided delta.[2]
