More than 250 properties were flooded along Kenwith Stream, with flood depths reaching 1.5 metres in some locations in 1979. This led to the construction of the Kenwith Flood Storage Reservoir by Torridge District Council in 1983, as part of the flood defence scheme. This was adopted by the National Rivers Authority (now Environment Agency) in 1989.
The reservoir overtopped in June 1993, following 26 hours of heavy rain and high tides. This flooded a significant number of residential properties in Bideford. The scheme was then reviewed and improved by raising the reservoir embankment to create more storage capacity.

Under the Reservoirs Act of 1975, reservoirs above 25,000m3 capacity undergo a statutory 10-year inspection. The purpose of the inspection is to identify any requirements needed to maintain and improve the resilience of the structure.
The latest inspection resulted in 7 mandatory and 5 non-mandatory requirements which the Environment Agency will deliver. These actions are being delivered under one project, split into three phases.
Secondary storage outfall works are currently programmed for 2027.
Head to the Environment Agency website for full details on the work being carried out at each phase, with detailed information and a timeline.
