"The River Moselle, also referred to as Moselle Brook, is in North London and flows through Tottenham towards the Lea Valley. The river was originally a tributary of the River Lea, but it now flows into Pymmes Brook, another Lea tributary.
The name derives from 'Mosse-Hill' in Hornsey, the high ground containing one of the river's sources, and bears no direct etymological relationship to the major continental Moselle River. The hill area also gave its name to the district of Muswell Hill and for a time the river was known as the Moswell.
"Unlike the Hackney Brook further south, the Moselle is not a "lost river". Although long stretches have been culverted (Moselle Avenue in Noel Park runs above the culverted river), it does not disappear into the London sewer system and much of its route can be easily traced. It can be seen flowing overground in Tottenham Cemetery (right) and Lordship Recreation Ground, and gave its name to the Broadwater Farm area between the two."
