A water monitoring system, funded with $200,000 from the NSW Government, was installed in 2013 in response to community concerns about a possible link between low water levels in the lakes and mining. Water levels have been monitored since then.
The monitoring system is managed by WaterNSW to provide publicly available near real-time information on lake water levels, groundwater levels and local meteorological (weather) information for each of the 5 Thirlmere Lakes and Blue Gum Creek, which is a creek that connects to the lakes when they are full.
An inter-agency working group, which was led by the former OEH and included scientists from the Office of the Chief Scientist and Engineer, the former OEH, the Office of Water and the then Sydney Catchment Authority, oversaw the establishment of a monitoring program for Thirlmere Lakes. This working group now involves scientists from the Office of the Chief Scientist and Engineer, Department of Planning, Industry and Environment (formerly OEH), the Department of Industry, Lands and Water, and WaterNSW, and is overseeing the Thirlmere Lakes Research Program.
Near real-time data is available for the water level in each of the 5 lakes in Thirlmere Lakes National Park and Blue Gum Creek. Rainfall data is available from a gauge located about 5 kilometres north of Thirlmere Lakes.
