Motuoapa Marine redevelopment update - September 2016
This month saw the removal of the marina island and growth of the reclamation area. Seay Earthmovers finished excavating the marina floor using earthmoving equipment and the marina water level is slowly coming up through recharge from the floor. Once the basin is at the same level as the lake, the short arm causeway will be removed.
Rock riprap has been placed around the existing marina boat ramp to provide additional stability and better launching conditions for ramp users.
Next month will see the dredging equipment established onsite and the marina basin floor tidied up. The dredgers will then move to the channel and commence dredging to 2 metres below chart datum.
The launching ramp nearest the Motuoapa Bay Holiday Park and the channel will be closed once the dredgers enter the channel, however it will be temporarily reopened over Labour Weekend 21-24 October.
All boaties are to stay well clear of machinery operating in the area as the channel will be a high risk construction area for the duration of the closure.
Oruatua is the nearest available launching ramp and is working well due to the lake level being approximately 1.2 metres above chart datum. Alternatively, Tokaanu, Mission Point and Motutere ramps are also available and are all covered by one of our boat ramp permits which can be purchased online at ramp-permit-taupo.dia.govt.nz.

Motuoapa Marine redevelopment update - July 2016
Works have commenced at the Motuoapa Marina. After consultation with Waikato Regional Council, the construction management and erosion plan has been approved and the main civil works contractor (Seay Earthmovers Limited) has established onsite.
The launching ramp is now closed and the marina cordoned off to enable the installation of a silt curtain to be erected in the lake to reduce any plume from construction. Seay Earthmovers Ltd (Seay) have been quarrying rock for the exterior wall of the reclamation area which will start arriving onsite during the following weeks.
Seay’s intended method is to bund off the marina entrance with
gravel contained in one tonne bags, in an endeavour to pump the water out of the marina and complete the majority of the earthworks in a semidry area within the marina basin.
Bellingham Marine NZ Ltd will be onsite December 2016 to install the floating structures and the marina is expected to reopen in April 2017.
