The image depicts a section of the River Colne at the Colchester Millenium Weir (Middle Mill Weir) in Colchester, United Kingdom, observed under bright daylight. In the foreground, spanning the left side and extending into the lower center, a multi-stepped weir, constructed from dark-colored material, is actively releasing water, generating white foam and significant turbulence. Directly below this cascading water, the river displays substantial green algal growth along a submerged structural edge. A brick retaining wall forms the left bank above the weir, topped with a black metal fence adorned with decorative cutouts, possibly depicting fish or otters. Beyond this fence, dense green foliage and mature trees are visible. To the right, the main body of the river flows, appearing dark blue-green with scattered surface ripples and small patches of foam. The distant right bank is heavily vegetated with reeds and trees, behind which a light-colored wooden fence is partially visible. No individuals are present in the scene.
