The Loing Barrage at Saint-Mammès

This 1885 version of the Loing barrage at Saint-Mammes represents Sisley's continued fascination with the same site visible in the 1884 and 1885 canal lock paintings — the working water infrastructure of the Loing valley examined from multiple angles and in varied conditions. His persistence with a limited geographic range — the few miles of river and canal between Moret and Saint-Mammes — parallels Cezanne's engagement with Mont Sainte-Victoire and Monet's repeated haystack and cathedral series, suggesting that all three saw the systematic examination of a known subject under varying conditions as a fundamental Impressionist method.

The barrage structure — weir, spillway, turbulent water below — is rendered with structural clarity while the water itself is painted in animated, energetic strokes conveying movement. The surrounding landscape is loosely handled. Sisley's palette for water in motion uses whites, pale blues, and grey-greens in varied directional marks.
