This is lock 48 on the Main Line of the Grand Union Canal. It is the second to bottom lock of the 5 lock Knowle flight. The Knowle locks are all double width, broad beam locks of approximately 14’ 6” width with a total rise of 41’ 10”.
The Grand Union Canal Main Line runs for 137 miles through 166 locks from Brentford on the River Thames to Salford Junction in the north east of Birmingham. All the locks are double width locks except the final 11 locks in Birmingham. The Knowle flight are the first double width locks heading south from Birmingham.
The Grand Union Canal was formed in 1929 from many separate canal systems. The Main Line itself was formed from the following four canals:
- Birmingham & Warwick Junction Canal (Salford to Bordesley)
- Warwick & Birmingham Canal (Bordesely to Warwick)
- Warwick & Napton Canal (Warwick to Napton)
- Grand Junction Canal (Brentford to Braunston)
There is a five mile section from Braunston to Napton which is actually the Oxford canal. This section was never bought by the Grand Union Canal Company.
Today the Grand Union Canal consists of:
- Grand Union Main Line
- Grand Union Leicester Section
- River Soar
- Erewash Canal
- Northampton Arm
- Aylesbury Arm
- Wendover Arm
- Slough Arm
- Paddington Arm
