2017 Living Lake Symposium

The sixth Living Lake Symposium was held on November 9th and 10th, 2017. The weather turned on a lovely sunny day for the field trip which took us up the catchment to Whitecliffs and then back to Te Waihora/Lake Ellesmere. We visited points of interest and some of the practical projects and research that is currently happening in the catchment.

A great range of speakers presented at the Symposium day covering a range of topics from mudfish to measuring contaminants from cow pat runoff! Read more and see the presentations here.

A very interesting and informative two days were had.  A great thanks to our generous sponsors whom make the event possible.
