An American water quality expert is to share his knowledge at a public meeting in Rotorua.
Dr Dale Robertson will speak about his experiences of restoring Delavan Lake, Wisconsin at the Rotorua Te Arawa Lakes Programme Science Evening on November 20.
Bay of Plenty Regional Council lake operations manager AndyBruere said Dr Robertson's experience was relevant to the area.
"His presentation on restoring Delavan Lake highlights the importance of reducing nutrients within a catchment to restore water quality. It's incredibly relevant to the situation we currently have with Lake Rotorua," he said.
Excessive nutrient loading into Delavan Lake resulted in the lake becoming hypereutrophic meaning it was rich in nutrients and had severe blue-green algal blooms. Dr Robertson was part of a team which led an extensive rehabilitation effort. Other research important to the Te Arawa Lakes Programme will be shared at the science evening, including presentations about how to farm in an environmentally and economically sustainable way, and on projects that are taking place in Rotorua to monitor local water species such as koura (freshwater crayfish), kakahi (freshwater mussels) and koaro (native freshwater fish).
The science evening will be held from 6 to 8pm at the Holiday Inn, Tryon St. You can RSVP online at www.rotorualakes.co.nz or call Hariata Ngatai 0800 884 881 ext 7445.
