context_page_description: The Brent Reservoir is a reservoir between Hendon and Wembley Park in London. It straddles the boundary between the boroughs of Brent and Barnet and is owned by the Canal & River Trust. The reservoir takes its informal name from a public house called The Welsh Harp, which stood nearby until the early 1970s. It is a 68.6-hectare biological Site of Special Scientific Interest, the only SSSI in either Borough and among more than 30 SSSIs in London.
  The reservoir is fed by the Silk Stream and the River Brent. Its main outflow is the River Brent. Its smaller outflow is a feeder channel to the canal system. It holds an estimated 1,600,000 m³. In 1994 when the reservoir was drained more than 3,000 kg of fish were captured, 95% of which were roach. However, fishing is prohibited.
  The reservoir has a sailing centre, home to Welsh Harp Sailing Club, Wembley Sailing Club, the Sea Cadets, and the University of London Sailing club. In 1960, it also hosted the Women's European Rowing Championships.
context_section_description: Many other forms of wildlife have also been studied and were documented in the Birds of Brent Reservoir. There have been 31 species of butterfly at the reservoir, including breeding marbled white and ringlet, the closest site for these to the centre of London. The most recent addition was brown argus in 2015. Scarce species include a single dark green fritillary in 1999. Prior to the construction of the reservoir, marsh fritillary used to breed. Dragonflies and damselflies have been studied and 15 species have been seen, of which 12 breed at the reservoir.
