Ralph Gregory, waterway supervisor for the Canal & River Trust, said: “We have a team in the water who remove the fish by temporarily stunning them with an electrical current. We then catch them in nets before they are transferred to large bins filled with fresh water and then safety emptied back into the canal outside the works area.
"Once the fish are removed we can then get in the empty lock, carry out repairs and install the new lock gates, which are 25 years old and weigh one a half tonnes. This is a major piece of work at the start of our programme to improve our canals and rivers over the winter period.”
This winter we are spending £45 million on essential repairs, restorations and routine maintenance to our canals and rivers. We're holding a number of free open days so that you can catch a glimpse of the craftsmanship that went into our waterways' original 18th Century design.
