A full year of results from the sediment traps at Whangateau and in the footprint of the proposed marina at Sandspit indicated a likely filling rate for the marina of 329.3mm in one year. This is far in excess of the estimate of only 30mm from the marina proposers. There was no experimental verification or ground truthing of that theoretical estimate, despite the SYCMS having ample time to do so.

Family Planting Site Ready to Go!

This event is planned for Saturday 19th May with a bad-weather backup day of 20th May

A beautiful site in the Omaha Valley is fenced, spot-sprayed and ready for planting to help reduce sediment input into the Whangateau Harbour.  Experience in other catchments has shown that siltation in estuaries can be significantly reduced if stock is excluded from water ways, and stream banks are planted with suitable native vegetation.

Whangateau HarbourCare Group, in conjunction with Auckland Council and land-owner John Williams, are hosting a public planting day on John’s property in Omaha Valley Road, below the magnificent backdrop of Mount Tamahunga.  John and Martha Williams have already carried out several riparian plantings over an eight-year period, and the earlier plantings are looking really good.

This event is planned for Saturday 19th May with a bad-weather backup day of 20th May.  Starting at 10 am, the first session will run to around midday when barbecue sausages and drinks will be provided.  For those keen to do more, or others who can only make it in the afternoon, a second planting session will begin around 1 pm finishing by around 3 pm.
