Waters of the Waikato is a synthesis of information about the river today from a wide range of sources. It features 48 authors writing about a range of issues, including iwi values, water quality and the ecological health of the river. The 15 chapters highlight information gaps and emerging issues that will help guide decision makers in their consideration of future river management issues. Some important issues highlighted in the book include:
The role of land management in maintaining water quality, reducing nutrient and sediment levels in the river, and protecting wetlands and lakes linked to the river
The effect of pests - such as koi carp, grey willow and introduced weeds - on water quality and native fish and plant life
How man-made structures can affect the movement and breeding of fish in the river.
Besides the way that human activities affect river flows, sediment and water quality, the book also considers ecological issues affecting plankton, invertebrate life, fish and birds, such as the impact of introduced pests on river health.”
The book features chapters devoted to the lowland lakes and wetlands on the river floodplain, which form an important part of the lower river ecosystem.
