In the 1620s, there was discontent in the region through which the New Bedford River now flows, as the land was regularly inundated by flood water. Francis Russell, 4th Earl of Bedford, who owned large tracts of land in the vicinity, agreed to carry out drainage works in 1630, in return for of the land which would be reclaimed. He was joined in the project by thirteen other adventurers, who formed a corporation and obtained a charter to carry out the work in 1634. The Dutch engineer Cornelius Vermuyden was engaged to oversee the work, which included nine major drainage channels, including the Bedford River, which ran from Earith to Salter's Lode. The tract of land through which it ran became known as the Bedford Level, and the scheme was declared to be complete in 1637. However, in 1638, that decision was reversed, and King Charles I became the undertaker to ensure the work was completed. The adventurers were given for the work that had already been carried out, and further work was again to be overseen by Vermuyden, but little work was done, as the English Civil War intervened. The existing works were neglected, and some were deliberately damaged during the hostilities.
