Originally intended as a non-navigable feeder to supply water (from the abundant streams of the Chiltern Hills) to the Tringford reservoirs which supply the Tring Summit, it was widened to navigable status before completion. It served for 100 years as a navigable watercourse from the Grand Junction Canal to the town of Wendover before it was decided that it leaked more water than it passed to the reservoirs. Stop planks were inserted at Little Tring and the remainder was made un-navigable. Revival interest came from 1967, and a rally in 1979 hoped to prevent the Arm's complete abandonment. The Wendover Arm Trust was set up in 1989, phase 1 of restoration was completed in 2004, and the new winding basin opened in 2005.
The Wendover Arm is currently only restored to 1.3 miles long, running from Bulbourne Junction on the Grand Junction Canal (Grand Union) to a new winding basin at Little Tring. With the exception of Heyfords Flour Mill which is a major employer in the area, the countryside is very rural and open. The canal is very shallow and narrow as far as Tringford Pumping Station, but opens out into the new basin at the current head of navigation. Designated moorings have been supplied.
