The stepping stones are currently:
Latest measurement at 2020-10-26 15:45 GMT is 0.181 metres.
What is this?
This page aims to predict whether the stepping stones over the River Dodder near to Dodder View Road in Rathfarnham are passable based upon the river's water level.
The OPW (Office of Public Works) has a water level meter approx 1.4km downstream at Waldon's Bridge on Orwell Road. Based on the data available from this indicator, I take a prediction on whether the stepping stones upstream are passable or flooded.
Why do this?
These stepping stones are a popular way for pedestrians from Rathfarhnam and Churchtown to access Bushy Park.
When it rains and the river level rises, these stepping stones often end up flooded and impassible. It's not possible to tell from a distance if the water is too high, and a lot of people end up walking to the river crossing, find it flooded, and then face the prospect of a 10 minute detour to the nearest bridge across the river and into the park.
This page aims to give people an indication when the stepping stones are flooded before they get there, and enable them to make alternate journey plans!
How accurate is this?
It's a prediction based upon the water level on a different section of the river, and so I make no guarantees about the accuracy of the tool.
However, I have observed a few times that the water is skimming over the top of the stepping stones when the water level at Waldon's Bridge is recorded as 0.25 metres. And so the tool is currently set to say the stepping stones are flooded at levels over 0.22 metres.
