Abstract: This data shows real-time water level data for water monitoring stations in the Office of Public Works hydrometric network for the last five weeks. Water level data is collected using data loggers. A data logger digitally records the water level at set time intervals using a pressure transducer immersed into the water body, or by using an ultrasonic receiver.

There are daily, weekly and monthly files, but as all data is on monthly files it is only necessary to download these. Up to date list of hydrometric stations is in geojson file containing longitude & latitude co-ordinates, station name & station ref - http://waterlevel.ie/geojson/. This file must be consulted for latest list of hydrometric stations. Station numbers above 41000 should NOT be used. Only CSV files ending in OD, 0001, 0002 and 0003 should be used where: OD - Water Level in metres from Ordnance Datum (may be Poolbeg or Malin) 0001 - Water level data in metres 0002 - Temperature (may be subject to significant heating in warm weather - not representative of water body temperatures) 0003 - Battery voltage

Times are reported in UTC/GMT. Irish Summer Time is one hour ahead of this.

Purpose: To support Flood Risk Management objectives through the collection of hydrometric data.

Provenance information The OPW has operated a national hydrometric network since 1939 consisting of auto-graphic recorders and staff gauges. With the introduction of electronic loggers and telemetry systems www.waterlevel.ie was established in 2012 as a method to gather this information to a centralised location and allow all users open access to the water level data being gathered in real-time. Displays last five weeks (35 days) of data (a 'month') and is updated every 15 minutes.
