The lake is situated about a mile (1.6 km) SE of the hamlet of [[Hartsop]] in the [[Patterdale]] Valley. It nestles between [[The Knott]] to its east and [[Gray Crag]] to the west and it is at an altitude of almost 1,400 feet (425 m). The lake is natural but was dammed in 1908 to provide a [[reservoir]] serving the Cumbrian town of [[Penrith, Cumbria|Penrith]]. It is fed from the south by Hayeswater Gill, which rises close to the route of the Roman [[High Street (Lake District)|High Street]] and continues to Cow Bridge where it joins the outlet stream from [[Brothers Water]].
It had not been used as a reservoir since 2005 and United Utilities removed the dam and restored it to a mountain tarn in the summer of 2014. A new footbridge over Hayeswater Beck was also constructed 250 yards downstream from the tarn outlet channel.
Hayeswater Tarn is also a popular yet remote destination for adventurous anglers and fly fishermen and women, with the tarn holding a good number of native wild brown trout. Tadpoles, caddis and olives are prolific and make up a big part of the trout`s diet. On occasion osprey can be seen over the tarn.
