What thought has been given to protecting the river mouth and allowing flow into the harbour?

Greater Wellington ensures the river mouth is clear to allow floodwaters to flow out to the harbour. If we stop extraction, a sandbar will form and block the river mouth, increasing the risk of flooding in the Hutt Valley floodplain. A groyne (barrier) to protect against southerly conditions will have a similar impact at the river mouth. Greater Wellington has resource consent to extract from the river mouth and keep the channel clear.
