Stakeholder Study: Resource Management of Wairarapa Moana
Natalie Diltz Jena Mazzucco Austin Scott Jeffrey Sirocki March 2, 2016 STAKEHOLDER STUDY: RESOURCE MANAGEMENT OF WAIRARAPA MOANA Identification and Analysis of Wairarapa Moana Stakeholder Opinions Regarding the Management of the Blundell Barrage Gates Abstract This project aided the Greater Wellington Regional Council (GWRC) in collecting opinions from five stakeholder groups concerning management of the naturally flooding Lake Wairarapa in New Zealand. Our team conducted a total of twenty-nine interviews with the Rangitāne (Māori), Department of Conservation, South Wairarapa District Council, landowners, and recreational water users regarding the Blundell Barrage Gates which play a vital role in flood management. Interview discussions indicate that water quality, sources of pollution, water levels, flood management, and future operation of the barrage gates are controversial. We identified communication, collaboration, and education as three areas of focus for the GWRC as they continue to improve their management of the region. i Executive Summary This project is concerned with Wairarapa Moana, a water system located in the Wairarapa region, situated on the North Island of New Zealand. Wairarapa Moana consists of the three main water bodies, shown in Figure 1; the coastal lake is Lake Onoke, the inland lake is Lake Wairarapa, and the main river is the Ruamahanga. The system is dynamic, which means water can flow in both directions. Both tidal movements and rainfall affect the direction of flow. The area is low-lying and sits between two mountain ranges exposing much of the land to seasonal flooding. The Greater Wellington Regional Council, the governing body for the Wellington region, developed the Lower Wairarapa Valley Development Scheme (LWVDS), to control flooding in the 1960s.
