Environment Agency advice issued
This updated warning is for caravans at Marnham Meadows Holiday Park only. Due to a blockage in the Old Trent watercourse near Marnham Meadows Holiday Park, off Hollowgate Road in High Marnham, properties and access in this specific area continue to be at risk. We are closely monitoring the situation. Our staff have checked the blockage and will continue to deploy pumps whilst river levels remain high. No other properties are currently at risk in the Marnham area. Resolving this situation is dependent on the River Trent water level falling to a depth that allows remedial works to take place sa
