About the project
This project seeks to determine what contaminants are entering Lake Ruatuna, when they enter the lake and where they come from. Specifically the objectives are to:
- Investigate how much and what type of contaminants are entering the lake, from where and at what times of year
- Identify freshwater values in the catchment
- Design and implement catchment interventions to reduce contaminant loads and protect existing values
- Demonstrate how to undertake catchment contaminant investigation and implementation of interventions
Living Water has partnered with Streamlined Environmental to undertake this work.
- Introduction of site specific interventions to achieve optimal reduction in contaminants
- Enhanced freshwater values
This project started in May 2019.
- Loggers have been placed in main waterways to help determine water flows and identify where most of the water entering the lake is coming from.
- Discussions with landowners and habitat assessments are underway.
- During rainfall events, flow gauging and water quality samples will be taken to determine contaminant loads.
- This load information will help determine the best course of action for the catchment, which may include establishing treatment riparian management zones or filtration wetlands for ephemeral watercourses
- It will also help identify where we will achieve the biggest reductions in contaminants entering the lake.
- Undertake mudfish surveys
- Investigate existing sediment traps and re-design to improve effectiveness if possible
