Pymmes Brook
Pymmes Brook is located in North London and named after William Pymme, a local landowner. It is a minor tributary of the River Lea. The brook mostly flows through urban areas and is particularly prone to flooding in its lower reaches. To alleviate the problem the brook has been culverted in many areas. Part of it is a Site of Borough Importance for Nature Conservation, Grade II. The Pymmes BrookERS community group works to improve the health of the river and its tributaries.
