The Waioeka-Otara Rivers Scheme covers the Waioeka River with a 825 km2 catchment and Otara River with a 350 km2 catchment.

The rivers converge at Ōpōtiki and flow out to sea. The Scheme includes substantial stopbanking of both the town and rural sections of both rivers.

This scheme includes:

  • 65km of stopbanks
  • 1 pump station
  • 124 flap gates
  • 118 culverts

Waioeka - Otara River Scheme 2021 end of year wrap

It’s been a busy year on the Waioeka and Otara Rivers Scheme. 

2021-12-22 - Waioeka - Otara River Scheme 2021 end of year wrap

It’s been a busy year on the Waioeka and Otara Rivers Scheme. Some of the highlights include:

  • A strengthening positive relationship with Waioeka and Otara Hapūs relating to gravel extractions and river works in general.
  • Geotechnical investigations at 15 locations along the rivers to check the condition of the stopbanks. This testing is essential to ensure that our stopbanks will continue to help protect our communities from flooding in the coming decades.
  • During September and October unsettled weather caused the Otara River to reach its first warning level a couple of times causing some river bank erosion concerns. Repairs are well on the way to strengthen the river banks and get the vegetation re-establishing.

Geotechnical investigations on the Waioeka River

We’re resuming our investigations around Ōpōtiki this week to check the condition of the stopbanks on the Waioeka River.

This essential monitoring will see contractors working on a number of mobile rigs and hand devices to find out the soil composition and stopbank stability.

It’s essential we undertake these investigations to ensure that our stopbanks will continue to help protect our communities from flooding in the coming decades.

The results will be used as part of determining if any upgrade or additional protection measures are needed.

Keep motorbikes off stopbanks

Please remember to keep motorbikes off stopbanks to help us keep these important flood defences in good order.

If you see any damage please report it to us.

Geotechnical investigations around Ōpōtiki

We’re doing some investigations around Ōpōtiki over the next few weeks to check the condition of the stopbanks on the Otara and Waioeka rivers.

We’ll be doing the tests at the 15 locations and thank you for your understanding as we undertake this essential monitoring to ensure that our stopbanks continue to help protect our communities from flooding.
