The Dutch River was difficult to navigate, and in 1793, the Stainforth and Keadby Canal was authorised, to provide a link from the Don at Stainforth to the Trent at Keadby. Although notionally independent, it was effectively under the control of the Don Navigation when it opened, probably in 1802. The Dearne and Dove Canal was also authorised in 1793, from Swinton to Barnsley, and was again under Don Navigation control, since most of the shareholders were also shareholders in the Don. A canal from Tinsley into Sheffield was delayed for years by opposition from the Don Navigation, but was authorised in 1815 and opened in 1819.
