Environment Waikato has provided $6250 from its Environmental Initiative Fund towards Waikato District Council’s wetland project for Lake Kainui (Lake D) in Horsham Downs.
The District Council intends to build a number of small wetlands next to the lake near existing drain entry points as part of an overall strategy to improve lake health and habitats. About eight other drains have been identified as future wetland sites.
The 25 ha lake is one of eight peat lakes in the area surrounded by rural land, with a recreation reserve around the lake. The lake has very high nutrient levels and habitat for wildlife has diminished.
The District Council proposed to control nitrogen levels by constructing wetlands with suitable vegetation to absorb nutrients and filter sediment. The project would benefit the lake’s health and recreational users, with long-term benefits for biodiversity protection and enhancement.
The total project is estimated to cost $26,00, with the District Council contributing $10,000 annually for maintenance and planting.
