Site Description
UK Upland Waters Monitoring Network (UK UWMN) site. Burnmoor Tarn is the largest 'tarn' in the English Lake District. It occupies 23.9 ha and lies at an altitude of 253 m 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 13 m. 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. Some data are managed by UK ECN Data Centre. Note: The area is the size of the catchment.

Geology
The bedrock is Ordovician andesite lava of the Borrowdale Volcanic series, to the south and east it is granite.
Vegetation
Mainly rough Agrostis-Festuca and Nardus grassland with Pteridium, Vaccinium, Calluna, and Sphagnum and is utilised for rough grazing by sheep and hill cattle.
Soils
There are thick till deposits in the catchment, notably on the southern side of the lake and the catchment soils are characterised by podsols and shallow peat rankers.
