Lakes Areare, Ruatuna, Rotomānuka
About the area
Globally peat lakes are rare ecosystems – the Waikato Region is home to 31 of them. These lakes formed over thousands of years and are home to species that have adapted to their unique conditions.
Classified as ‘acutely threatened’, the Waikato peat lakes are important historically, culturally and environmentally.
Living Water is focused on three specific lakes – Areare, Rotomānuka and Ruatuna. Improving water quality of these lakes will help mudfish, bittern, fern birds, dab chicks and long-finned eel return. It will also enhance recreational use.
Lakes Areare, Ruatuna and Rotomānuka have elevated levels of nutrients, sediment and pathogens, and considerable nutrient stores within lake sediments. This has been caused by the various productive land uses in the area and the highly modified hydrology and drainage systems. Enhancement of water quality in these lakes is extremely difficult and will require a range of remediation measures.
Living Water’s key focus is restoring unique peat ecosystems, enhancing habitat around the lake margins, and transforming agricultural drains into healthy waterways.

Trialling growing aquatic plants growing on a buoyant mat to capture incoming contaminants
Sediment traps are simple, low-cost excavations in a watercourse or near a waterbody that capture and reduce the downstream movement of gravel, sand, and silt.
Trialling planting hydro-seeding native sedge seeds in riparian zones to determine success and cost vs conventional planting.
Living Water has partnered with landowners, community and iwi to carry out lake restoration activities
Community engagement is key to any project. Once the project is over, it’s the community that keeps it alive
If children are engaged, they can develop a sense of ownership of an area, see the positive changes in the area over the years, and influence their parents to become involved.
Reducing pest fish in Lake Ruatuna in order to re-establish native macrophytes to improve water quality over time.
Reducing the biomass of invasive macrophyte Ludwigia by aerial spraying with drones, rather than hand weeding or excavation.
Investigating what contaminants are entering Lake Ruatuna, when they enter the lake and where they are coming from?
