Severn Navigation Co
1837 The company had abandoned its plans to deepen the Severn up to Worcester to 12 feet and had formed a new company to cut a new channel to Worcester with depth of 6ft 6 inches and a further channel of 6ft to Stourbridge[1]
1858 A lock and weir had been built at Worcester as the first part of the planned improvements of the Severn Navigation Commissioners. Work then began on improving the Severn at Tewkesbury following the plans of Mr E. L. Williams. The water level from Tewkesbury to Worcester would be raised by building a double lock and weir at Tewkesbury, so as to allow small coasters to reach Worcester [2].
1878 Mr E. L. Williams raised concerns about the plans of Liverpool to extract water from the Severn and its implications for navigation on the Severn[3]
