Flooding from Storm Chandra

PXL 20260127 082619107.MP

There’s flooding in Churchtown and Rathfarnham this morning as the River Dodder and its feeders burst their banks. At the Dodder Stepping Stones, I captured the water level at 1.92 metres high. For reference, the stepping stones normally become unsafe at 23 cm. Here’s a short clip from where the stepping stones are – somewhere … Read more

Adjusting the thresholds

This winter we’ve seem several flooding events in the River Dodder after very high rainfall. I posted in November about the river height reaching 1.7 metres at one point – approximately eight times the height of the stepping stones, and high enough to leave silt on the footpath at the side of the river. One … Read more

Water level at 110cm

A couple of days ago there was an orange weather warning in place for 3 counties including Dublin for rainfall. I didn’t manage to capture a screenshot at the time, but I distinctly remember visiting this site at the peak of the rainfall, and seeing the water level at 110cm. For context, the height of … Read more

Stepping stone data unavailable

That’s the last time that the water level data was updated. This problem with the water level data not updating happened before, and it was related to … Read more

Problem displaying temperature and air quality data

I noticed today that the temperature/humidity and PM air quality numbers are not displaying correctly on the site. These numbers come from an API call to the sensor.community site, and it seems like the API is currently broken: See their forum for more details: https://forum.sensor.community/t/is-sensors-api-currently-down/4604 This has broken this site’s integration, and it’s also broken … Read more

Updating the Temperature and Air Quality API calls

I was finding that any page loads of the Temperature and Air Quality pages were taking a long time, and sometimes timed out without retrieving the data. To get the sensor data for the pages, I make an API call to the sensor.community site to download a small JSON file, and then parse out the … Read more

Water level data restored

Having reached out the the EPA, they established that the water level data feed that went to the OPW waterlevel.ie site had stopped working, and they were able to restore it. Therefore, the data from the EPA sensor at Waldron’s Bridge is now flowing again to the OPW site, and I’m able to automatically grab … Read more

Sensor now operated by the EPA

I reached out to the OPW to ask about the sensor data, and asked if it could be restored. And they got back to me, saying that the sensor has now been taken over by the EPA, and that I can maybe reach out to them to get access to the data. This is the … Read more

The waterlevel.ie sensor for Waldron’s Bridge (https://waterlevel.ie/0000009010/) has not updated with any data since 5th July 2024 – 20 days ago at the time of writing. The data from this water sensor is used by this site to indicate whether the River Dodder stepping stones are flooded or not, and without the data the site … Read more
