In the Hartsop Valley, Brothers Water is a small natural tarn lying at the northern end of Kirkstone Pass. It is at an elevation of 157 m (515 ft). Its relatively remote location means it is less popular than many other lakes in the area, but the displays of water lilies in July and other flora and fauna year-round make it well worth a visit. The tarn supports a trout population and is one of only four locations in Lake District where the Schelly, a rare species of fish, is known to live. Parts of the shoreline are privately owned and anglers will need to secure permission in advance to fish here.
