Inquiry into recent variations in water level in Thirlmere Lakes

Under the authority of the Minister for the Environment, the Thirlmere Lakes Inquiry Committee is authorised to inquire into and report on the following matters concerning recent variations in water level in Thirlmere Lakes:

1. historical, paleo-climatological, and other scientific records regarding lake levels, rainfall events and other natural or land management data related to the condition and circumstances of the Thirlmere Lakes
2. identification of patterns in the relationship between water levels in the Thirlmere Lakes and known rainfall events, land management practices or other factors
3. an assessment of current water levels in Thirlmere Lakes against identified patterns
4. recommendations for management actions to address the factors identified as likely to have a direct or indirect effect on lake levels and/or on the natural and cultural values of Thirlmere Lakes National Park
5. recommendations for future studies to better understand the hydrology of the Thirlmere Lakes and provide better information for future management
6. any other matters the Inquiry Committee considers relevant to the reasons for or responses to water levels in the Thirlmere Lakes.

In preparing its recommendations the Thirlmere Lakes Inquiry Committee may have reference to a wide range of information sources including, but not limited to: scientific data and studies including paleo-climatological studies; expert opinion; climate or other modelling; comparative information across the region; data from similar water bodies; historical information; private records (such as family photos or private data collections); and submissions from the public.

The Thirlmere Lakes Inquiry Committee will consist of the following members:

• a chairperson with senior qualifications and expertise in hydrology, geology, geomorphology, climatology, paleogeography and/or related natural processes relevant to the inquiry
• two members with qualifications and expertise in hydrology, geology, geomorphology, climatology, paleogeography and/or related natural processes relevant to the inquiry
• one member with qualifications and expertise in freshwater ecology, ecological management or natural sciences relevant to the inquiry
• one member with expertise related to mining practices and techniques including short and long term environmental effects.

The Thirlmere Lakes Inquiry Committee will as expeditiously as possible, but in any case on or before 30 June 2012, deliver a final report on the results of the inquiry to the Minister for the Environment.
