In this square-format photograph, Morgan focuses on the weir at Roath Park Lake, capturing the precise moment water breaks over the stone edge. The choice of black and white emphasizes the graphic quality of the architecture against the soft, blurred motion of the falls. By removing color, the artist draws attention to the play of light on the surface and the rugged geometry of the urban landscape.

The composition highlights a sense of quiet order within the Cardiff environment. The cascading water creates a natural gradient of grays and whites, contrasting with the dark, solid lines of the weir's structure. It is an observation of how man-made elements integrate with the park's ecosystem, offering a calm perspective on the intersection of city life and the natural world.
