CRT have announced the publication of the two reports on the spliway failure at Toddbrook in 2019.
They have said
The Canal & River Trust welcomes the Government-commissioned Independent Reservoir Review report from Professor Balmforth which examines the cause of the damage to Toddbrook Reservoir last summer and makes recommendations for the improvement of reservoir safety across England and Wales.
Both the Balmforth report and a separate independent report by expert reservoir engineer Dr Andrew Hughes, commissioned earlier by the Trust and also published today, identify that serious hidden design flaws, inherent in the concrete auxiliary spillway from the time of its installation in 1970, caused its partial collapse on 1 August 2019 following several days of heavy rainfall.
Since the incident last August, the Trust has implemented measures to enhance reservoir inspection and maintenance and will now be fully reviewing both reports and acting on their findings to ensure the ongoing safe stewardship of the reservoirs in its care.
