but also for water quality, water resources and habitat for wildlife. The study was expected to provide a short-list of routes, which would then be the subject of further consultation. By mid-2012, the merits of the ten routes had been considered, including the economic, environmental and technical issues involved, and a broad outline of the corridor for the link was scheduled to be published in September. After that, consultation with landowners and stakeholders took place, to establish the final route, for which design of the channel and the associated locks, bridges, moorings and pumping stations could then begin. By the end of the assessment process for the ten routes, two remained. One was route 1, the original suggestion which used the existing course of the South Forty-Foot Drain for most of its length, while the second was a new route, designated as route 11. Route 11 had become the preferred route by the summer of 2014. It involves widening the South Forty-Foot Drain from Donington to Surfleet, to a point near to the Black Hole Drove pumping station. A new lock would be needed at this location, but would connect to a new channel, rather than to the rest of the drain. It would pass under a new bridge on the A151, and the connection to the River Glen would involve another new lock. An environmental survey of other watercourses near to the route revealed that several provide habitat for nationally important plants and invertebrates. Precursors The idea of a link between the South Forty-Foot Drain and the River Nene is not new, as the first plans for such a connection were proposed in 1809. In that year, proposals for a new canal between the Oakham Canal at Oakham and the Stamford Canal at Stamford, which had been discussed in 1785, were revived, as part of a larger plan for a link from Stamford to the River Nene at Peterborough, and a connection from near Market Deeping, where the Stamford Canal rejoined the River Welland, northwards to the South Forty-Foot Drain. A bill for this, together with one for a rival scheme to link Stamford to the Grand Junction Canal, which also included a connection to the South Forty-Foot Drain, were put before Parliament in 1811, but neither met with any success. The idea was raised again in 1815 and 1828, but no further action was taken. Route Water quality
