Location: Botterham Locks, near Swindon on the Staffordshire & Worcestershire Canal.
Date: Wednesday 1st July 1998.
Equipment: Canon EOS 50e using 28mm f/2.8 lens.
Emulsion: Kodak Gold 200.
Keywords: canal locks, staircase pair, lock gate, filling with water, gushing water, water surge, foamy water.
Notes: looking at this picture, it appears that someone had opened the paddles to fill the second chamber before realising that the boat hadn't left the first chamber. This means that the spectacular surge of water would end up filling both first and second chambers, and that was technically unnecessary.
