What's happening in 2016-17

Project Maitai/Mahitahi is now into its third year.

This year will see a focus on improving our urban water quality by reducing pollution from roads, roofs and pavements washed into our streams through the stormwater network.

York Stream – a tributary of the Maitai River - is still a high priority, with work to improve water quality and riparian management, clean up litter and improve fish passage.  

We’re also continuing to work on understanding toxic algae and increasing public awareness about its dangers, improving riverside plantings, and developing a wetland at Groom Creek.  Improvements to fish passage will involve remediation of the Almond Tree Flat Ford.

If you’d like to know more about these projects please contact the Project Manager Jo Martin at jo.martin@ncc.govt.nz

York Stream Focus

York Stream 13 remove rock and litter 17Dec2015 2

Description: Improving York Stream water quality and fish habitat by identifying and removing pollutants and litter, and improving riparian management, fish passage, and community stream care activity

Objective: York Stream is a better habitat for aquatic life and is safe for children to play in, and local stream care groups play a key role in its management.

Urban Water Quality

urban water quality

Description: Investigating and applying methods to reduce pollutants in stormwater, and building community awareness of personal actions that can help reduce urban stream pollution.

Objective:  Our city streams are free of pollutants from preventable sources, such as litter, wastewater, pet waste, heavy metals, fine sediment, petrochemicals, detergents, pesticides, fertilisers, paint and industrial pollutants.

Streamside Planting

Maitai River planting day 1 2

Description: Planting more native plants along waterways to reduce erosion and sediment run off, provide shade to cool the water, and increase habitat for other native plants and animals.

Objective: Streamside planting and vegetation management in the Maitai catchment supports both Project Maitai/Mahitahi and Nelson Nature objectives, and provides opportunities for the public to get involved.

Groom Creek Wetland

groom creek

 

Description: Restoring and planting a wetland area at the base of Groom Creek, where it enters the Maitai/Mahitahi River, to filter out nutrients and sediment from the Groom Creek catchment.

Objective: Nutrient and sediment run off from the Groom Creek catchment is prevented from entering the Maitai River, and biodiversity in the Maitai Valley is enhanced, by the restoration of a wetland at the base of Groom Creek.

Cyanobacteria (Toxic Algae) Investigation

Susie Wood and Paul Fisher with students Oct 2015

Description: Managing Cyanobacteria (toxic algae) risk to dogs and humans, and finding out what causes Cyanobacteria blooms so those factors can be targeted.

Objective: Improved community awareness of cyanobacteria risk to dogs, and a better understanding of factors influencing cyanobacteria blooms.

Maitai/Mahitahi Ford Improvements

Almond Tree Flats ford fish passage barrier June20152

Description: Removing or modifying the fords on the Maitai/Mahitahi River so they are not a barrier to fish migration.

Objective: Fish are freely able to access the mid and upper reaches of the Maitai/Mahitahi and are not blocked by the Almond Tree Flats concrete ford.

Streamcare Information

Victory Primary School students trialling Against the Flow the Maitai River Game

Description: Informing the community about how to care for their streams, key issues and achievements, and opportunities to get involved.

Objective: The community know about and are supportive of Project Maitai/Mahitahi, understand that caring for our river is everyone’s job and not just a ‘Council project’, and know what they can personally do to contribute to the goal.
