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.

The challenge

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.

Our projects

Floating Wetlands Trial

Floating Wetlands

Trialling growing aquatic plants growing on a buoyant mat to capture incoming contaminants

Sediment Traps Trial

Sediment Traps

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. 

Hydro-seeding Trial

Hydro-seeding Trial

Trialling planting hydro-seeding native sedge seeds in riparian zones to determine success and cost vs conventional planting.

Engaging with the community

Engaging with the community

Community engagement is key to any project. Once the project is over, it’s the community that keeps it alive

Engaging with schools

Engaging with schools

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.
