A river level marker gauge is potent and ominous by its very presence in that it refers to depth or a possible depth.

It is fixed as a gauge to enable a measurement of uncertainty.

The gauge is totemic, it is sited so that its immediate environment can be measured and determined against it.

Within its totemic image are marked precise references to scale and inferences to space and time. Its preciseness is reassuring in our chaotic environment

The Marker has a duality. It positions itself as an anchor but also points  towards the vulnerability of its location.
