From an aerial perspective, we look down on the green algae and a lone rower who is sculling upstream of the River Lea (Also Lee) in east London, England. The words No Fishing have been painted by hand on a old Victorian lock that once served as a navigable route for barges to negotiate this inner-city waterway. With its source in the Chiltern Hills and ending in the River Thames, this stretch of river has seen development from Saxon times through to the building of the 2012 Olympic site at Stratford. Meticulously placing his oars in the water, he parts the organic growth with the slim boat's hull and looks over his shoulder to check his distance and angle as he nears the lock’s concrete spans.
