Mytholmroyd was severely affected by the Boxing Day floods in 2015 , when the River Calder and the canal both rose to cover the valley floor , and consequently the town centre of Mytholmroyd . It was the highest ever recorded river level . Hundreds of homes and businesses were devastated , with some buildings still empty in 2017 . The row of shops north of County Bridge partially collapsed into the river , and £ 10 million was earmarked for future protection of the village . The whole row of shops which partially collapsed have been fully demolished , along with homes along the riverbank at Calder Grove . By 2018 , Russell Dean Furnishers had their furniture showroom above ground level and the Co-op Food built a replacement store
