In the course of my hunt for the lost rivers of Walthamstow I came across this paragraph in the Victoria County History:
“Higham Hill sewer flowed from Chapel End across Blackhorse Lane to Dagenham brook. The brook flowed south to Leyton, joined by Moor ditch from Markhouse common. Most of Moor ditch was piped in the 1880s. Parts of the Higham Hill sewer, Dagenham brook, and Blackmarsh sewer west of the brook ( Its continuation in Leyton was known as Shortlands sewer), were diverted or filled in when the flood relief channel was built in 1950–60.”
And it was also marked on the 1840 map of Walthamstow. There was another lost river of Walthamstow to be staked out on foot.
I headed out on a sunny Friday afternoon, along Hoe Street and into Forest Road, which is shown as Clay Street on the 1777 Map of Essex at this point. The quest would start at the Water House, now the William Morris Gallery, as the 1777 map shows a watercourse flowing West from the moat in what is now Lloyd Park, in a more or less straight line to the River Lea. Comments on the Walthamstow lost river video (the Philley Brook) had mentioned a river flowing beneath Winns Avenue in Walthamstow. This aligned with the route of the stream rising in the Water House moat. However, descriptions of the course of the Higham Hill Brook and 19th Century maps place the source as Higham Hill Common, further north, but not so distant as to rule out a relationship (as discovered with the multiple sources of the Philley Brook / Fillebrook).
I headed in the direction of Priory Court, the shape of the road seeming to mirror the contours of the river on old maps. The assumption being that the river must cut through the post-war council estate and pass either through, or around Higham Hill Common Allotments. There were no massive indicators here, but on Higham Hill Road the point where the subterranean stream crosses was apparent. This also aligned with the site of Walthamstow Avenue FC’s Green Pond Road ground, now a housing estate. A former resident of the area, Robert, confirmed in a comment on the YouTube video that the river indeed flowed beneath the pitch: “which is why it had a reputation for poor drainage and matches always being postponed during late December and January. Also knew an old lady from my time attending At Andrews church who lived on Green Pond farm which is where the football ground and dairy were built on and she told me of her childhood playing by the brook in the 1920’s.”
From this point to the confluence with the Dagenham Brook the route was fairly clear – the walk taking me down Higham Street (where a footbridge is marked on an old map), and into Chamberlain Place. The river then passes through a huge new housing development, Blackhorse Yard, which includes plans to include the re-surfaced stream in the design. A rare example of daylighting in London.
Luckily for me the Higham Hill Brook meets the Dagenham Brook in the Forest Industrial Estate near two breweries so I was able to celebrate the successful conclusion to the walk with some fresh beer from Signature Brew.
