2013 State of the Lake
Te Waihora/Lake Ellesmere: State of the Lake 2013 – download it here
WET launched a new publication at the fourth Living Lake Symposium, held at Lincoln University on November 7 and 8, 2013. Focusing on sets of indicators for a range of different topics, several short reports by expert authors have been compiled to present an update on the state of the lake 2013.
More information – scroll down to find further reports and links on particular topics.
Please note, Environment Canterbury began updating their website in late 2016 and have removed or changed links to a number of the documents listed below. If a link for an ECan document or webpage no longer works, please contact ECan directly and they may be able to help you.
Environment Canterbury, as part of their sub-regional planning process for Selwyn-Waihora, have gathered together a large number of reports and presentations on a wide range of topics. The page can be accessed here and is well worth a visit.
The State of the Lake 2013 report includes an introduction and nine sections covering different topics. Additional reports and links for each topic have been added below, with some more information still to come for some topics.
Background information about the Lake can be found in The State of the Lake, Hughey et al, (2008). The individual chapters can be downloaded from the page on this website.
There are various sources of additional information, including Stephen Kitto’s 2010 MSc Thesis on the Environmental History of Te Waihora/Lake Ellesmere.
In order to select indicators to report on, first we asked “how will we know when we have achieved success?” In the State of the Lake 2013 report a table of desired outcomes for the Lake and associated values is included. This is derived from a range of planning and policy documents. For a full explanation please see the ‘Summary document’ prepared by WET in mid 2013.
2. Governance and Management
The relationships between the different groups involved in governance and management around Te Waihora is very complex.
