Botterham Locks on the Staffordshire and Worcestershire Canal consist of a two step staircase. Together a rise of 20ft 3in (about 62 metres) is provided. Straddling them is Botterham Bridge, No 42.
Staffordshire and Worcestershire Canal

The Staffordshire and Worcestershire Canal was opened in 1772, engineered by James Brindley. It cost a little over 100,000 at the time. It links the River Severn at Stourport to the Trent and Mersey Canal at Great Haywood Junction in Staffordshire. There are 43 locks (45 if you don't fancy the deep wide locks at Stourport) and the canal is 46 miles in length.

Staircase locks

In a staircase the upper gate of one lock is also the lower gate of the one above it. Operating a staircase is very different from operating a flight. It can be more useful to think of a staircase as a single lock with intermediate levels. As there is no intermediate pound, a chamber can only be filled by emptying the one above, or emptied by filling the one below; thus the whole staircase has to be full of water (except for the bottom chamber) before a boat starts to ascend, or empty (except for the top chamber) before a boat starts to descend. In an apparent staircase the chambers still have common gates, but the water does not pass directly from one chamber to the next, going instead via side ponds. This means it is not necessary to ensure that the flight is full or empty before starting. Examples of real staircases are Bingley and Grindley Brook. Examples of apparent staircase locks are Foxton Locks and Watford Locks on the Leicester Branch of the Grand Union.
