South west of Scafell, below the steep slope of Great How, is Burnmoor Tarn. This is one of the largest tarns in the Lake District. This tarn, which is approximately 40 foot deep, holds the following fish types, perch, pike and trout.
It would appear that this tarn is prevented from following the natural line of drainage into Miterdale by moraines, and empties southward, reaching the Esk at Beckfoot. Burnmoor Lodge, which stands near the southern shore of Burnmoor Tarn, was once a keeper’s cottage and is approximately two miles from the nearest road.
