Part 1 - Introduction

The Dingman Creek Weir was constructed in what is now Dingman Creek Conservation Area, off of Homewood Lane, in the early 1940s by the Alsop family, who were local landowners (the weir was also known as Alsop’s Dam). Although it is not know exactly when the weir was constructed, the structure appears to be present in 1942 aerial photography. Information from the local community indicates that the weir was built to generate waterpower for private use.

The weir (pictured above from upstream, and below from downstream) experienced structural failure before it was ever put to its intended use and was eventually abandoned. Most recently, the weir and the surrounding land, known as the Dingman Creek Conservation Area, came into the ownership of the City of London.

The weir represented a concern both in terms of public safety and watercourse health. The weir was one of more than 80 small barriers in the Upper Thames River watershed, including 32 in London.
