The structure on the River Kelvin has been in place for several weeks - but engineers have just revealed the inspiration that lies behind it.
A makeshift dam has taken shape near to the Old Flint Mill on the River Kelvin Walkway.
And Scottish Water's contractors have turned to the ultimate aquatic engineers - beavers - to overcome the elements.

The structure is providing protection as engineers go about the latest phase of a multi-million pound project to help improve the environment and water quality on the river.
Teams are busy stabilising the river bank and constructing a new waste water infrastructure.
Paul Milligan, amey Black and Veatch (aBV) communication manager, said: “Our site team has been faced with heavy rainfall over the past few months and the high river level has made working conditions pretty challenging.
"By creating a false embankment, the dam helps divert the water away from the river bank and means that the engineers can go about their work and keep the river flowing.
"It creates much safer working conditions and it’s been quite a talking-point for the Kelvin Walkway users interested in the work that’s going on here.”

The £15m environmental project in the west end is being delivered by Scottish Water’s alliance partner amey Black and Veatch (aBV) and involves the installation of new and improved waste water infrastructure at 11 separate locations along the River Kelvin.
The new infrastructure will help prevent items which are wrongly flushed down the toilet.
Items like rags, baby wipes, plastic cotton buds will be prevented from entering the River Kelvin during severe storm events.
The structures will also reduce the frequency and volume of waste water spillages in storm conditions.
