The River Brent and the Grand Union Canal share a common course for large parts of their route below Hanwell Locks and both join the Thames at the same place in Brentford. The River Brent is on the right here, whilst the Grand Union Canal passes through Brentford Gauging Locks on the left. At the gauging locks the toll clerk checked to see how much cargo each boat was carrying so that he knew how much toll they should pay to use the canal. To do this he used a special stick known as a gauging rod to measure how high out of the water the boat was sitting. From this he could calculate the weight of cargo on board.
