Actions to prevent lake pest fish and weed infestation and to restore lake quality are the topics of our 2019 symposium.

Catfish are now well established in both Lakes Rotorua and Rotoiti. It is critical that they do not spread further to other Rotorua lakes. LWQS proposes a clean-boat certification programme. The support of all lake users is vital to preventing the spread of these pests.

Much progress has been achieved across our Rotorua lake catchments in reducing nutrient inflows. More still needs to be done. Many of our lakes remain at risk of further degradation. Lake Tarawera water quality continues to deteriorate. Lake Rotoehu has not responded, as expected, to ten years of control actions.

Speakers will present on:

  • US experience in freshwater biosecurity and lake restoration.
  • NZ Government priorities for pest and weed control; and freshwater management.
  • Other NZ experience in preventing the spread of invasive species.
  • NZ regulation framework supporting freshwater biosecurity.
  • The LWQS proposal requiring all lake users to self-certify that they are not carrying pests between lakes.
  • New funding strategy for the non-Deed lakes.
  • New knowledge of the science and practice of weed and pest management, geothermal lake chemistry and actions required for full lakes’ restoration.
  • The challenge to restoring Lake Tarawera and considering its surrounding eight lakes and their catchments.

Key Note Speakers


Dr Lars Anderson

Dept of Agriculture USA (Retired)

Lars has over 40 years experience focused on solving aquatic weed problems in the US, Brazil, Australia, Europe, and Mexico in lakes, ponds, reservoirs, irrigation systems, estuaries such as Lake Tahoe and the highly complex riparian systems such as the Sacramento San Joaquin Delta and the San Francisco bay lands.

His expertise and consultancies have helped result in successful fully integrated, eradication programs for hydrilla and the marine alga Caulerpa taxifolia, and most recently Elodea canadensis (and hybrids) in Alaskan lakes.


Prof Troy Baisden

Professor & BOPRC Chair in Lake and Fresh Water Science, University of Waikato

Professor Troy Baisden holds the Bay of Plenty Regional Council Chair in Lake and Freshwater Science. He specialises in understanding the flow of nutrients, water and carbon through terrestrial ecosystems and resulting impacts in freshwater. He holds a PhD from the Department of Environmental Science, Policy and Management at the University of California, Berkeley. Troy studies land-to-water nutrient management and issues such as climate change at catchment scales, with a focus on implementing the Bay of Plenty’s vision of a mountains- to-the-sea research programme driven by community and iwi aspirations.


Hon Eugenie Sage

Minister of Conservation, Land Information, Associate Minister for the Environment

Eugenie Sage is the Minister for Conservation, Minister for Land Information New Zealand and Associate Minister for the Environment.

She has been a Green MP since 2011. Before that she was an elected Environment Canterbury regional councilor. For much of her adult life she has worked to better protect Aotearoa/New Zealand’s natural landscapes and seascapes, and the indigenous plants and wildlife that call them home, including 13 years with the conservation organisation, Forest and Bird.


Guy Salmon

Ecologic Foundation

Guy Salmon leads Ecologic, a “think-tank” working at the interface of the environment and the economy. Guy’s work focuses on research, policy advice, and consultancy where this can improve environmental outcomes. He has had a nine-year involvement in the consensus-building Land and Water Forum, and two years ago, advised the Rotorua District Council in its successful application to the Freshwater Improvement Fund for Lake Tarawera.


Past Symposia

The Lakes Water Quality Society – which, including a previous life as the Lakeweed Control Society, is now almost 50 years old – organised in 2001, the first in a series of symposia in conjunction with the Royal Society of NZ (Rotorua Branch). These symposia were initiated for two reasons : firstly, public concern over a decline in lake water quality, especially the spread of blue-green algal (cyanobacterial) blooms; secondly, the limited amount of basic research being conducted for lake water (as opposed to applied research and monitoring). Following the success of this initial foray, subsequent symposia were also organised, and the Society now has a well-deserved reputation for high-quality, current and relevant content for these events.
