This is a water level recorder located on the Harbour wall at the north side of Lough Furnace. It records the lake level every 15 mins on a continuous basis. The lake level is determined by the inflowing discharge from lough Feeagh through the Mill race and Salmon Leap, and from the Yellow river and the Black lakes. Tidal flow from Clew bay also impacts the lake level. These data are real time (GMT) and raw - they have not yet been through the full quality checking procedures.
